Develop an android, IOS App for my Food Business

Please do not apply if you have not built and delivered this type of app before. We are looking for an experienced mobile developer to build a professional iOS and Android ordering app for our food business. Customers should be able to browse the menu, view prices and images, add items to a basket, submit orders, and receive order-status notifications. The app will require a secure backend/API, database, admin panel, customer order management, push notifications, and reliable handling of failed or duplicate requests. We expect clean architecture, secure authentication, proper validation, production-ready deployment, and support with Apple App Store and Google Play submission. I have attached a technical requirements document outlining the proposed functionality and technical expectations.

Help to check and develop a web app

We have built a small web app and we want an independent technology professional and app developer to check it over, fix what the check finds, and then look after it. We are not asking anyone to rebuild it. We are seeking two things: your costs, and your approach. Tell us what you would do, in what order and why, as well as what it would cost. We have not set a budget and we are not looking for the cheapest quote. We are looking for the supplier who understands the job. What we want you to quote for Please price each of these separately so we can compare quotes, and say clearly what is included and what is not. With each one, tell us briefly how you would go about it. A. Code and security review (fixed price) • Read the source code and tell us what is wrong, badly built, or risky. • Look at the access code. We know it is a turnstile rather than a lock. Tell us whether that is reasonable for a free tool, and what a better option would cost. B. Testing on real devices (fixed price) • Test on current and older iPhones and Android phones. • One behaviour matters more than any other: when a builder taps the report link in an email, does it open the app they installed on their home screen, or a separate browser window that cannot see their records? Tell us what actually happens on each platform and what we should do about it. • Also check adding to the home screen, working with no signal, and the camera and voice dictation. C. Fixing what A and B find (price or day rate) • We expect to agree the list of fixes with you before you start. • Quote a fixed price if you can, or a day rate with an estimate. D. Keeping it going (annual price) • A few days a year: small fixes, the yearly access code change, and updates when the Code changes. • Tell us your response time for something broken, and how we reach you. E. Optional, priced separately — tell us if you would recommend it • Putting the app in the Apple App Store and Google Play. Note that it already installs from the browser without this. • A small server so customer reports arrive automatically instead of by email, and records are backed up off the device. This would mean we hold customer data, which is a decision we have not taken. Price it, but do not assume it.

Test a dating app

Project Title: QA Testers Needed for Dating App CIS Market (excluding Russia and Ukraine) — Manual Testing Project Description: Hi I'm a product owner based in Silicon Valley, California. I'm launching a new dating app that will operate only in the CIS market (excluding Russia and Ukraine). I need 3–5 reliable QA testers specifically from these countries: Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, Azerbaijan, Armenia, Georgia, Belarus, Moldova, and others. Why you: It's important to me that the app is tested by people who actually live in these countries, understand the local mentality, culture, language, and the way people here date. I want to build a product that is genuinely convenient and useful for your country and your people not just "another app." That's why your opinion and your perspective are critically important to me. This is not a "click and forget" gig. I take my project seriously I invest my time, money, and soul into it and I'm looking for equally serious people who want to build something worthwhile. Scope of Work: Must have an iOS device. Complete the full user flow: registration → profile setup → browsing → matches → chat → settings. Test edge cases (empty fields, bad photos, rapid tapping, network switching, etc.). Document bugs with screenshots or screen recordings and clear reproduction steps. Submit a structured report (template provided). Separately provide feedback as a resident of your country: what's convenient, what's not, and what would be useful specifically for your market. What I'm looking for: Basic understanding of manual QA and software testing. Ability to write clear bug reports (not just "it doesn't work"). Residency in a CIS country (excluding Russia and Ukraine). Own iOS smartphone. Stable internet connection. Attention to detail quality over speed. Experience with TestFlight or Google Play Console internal testing is a plus, but not required. What I offer: $45–65 per tester depending on the depth of your report. $25 bonus for each critical bug you find and document properly. Clear test plan and report template no guessing required. Potential for long-term collaboration on future app releases. To apply, please include: Country of residence. Device model and OS version. A short note about your QA or testing experience (personal projects count). One example of a bug report you've written (or describe how you would report an app crash). Start your bid with "QA Dating App CIS" so I know you read the full post. Serious applicants only. I will review the quality of your report before releasing payment. I take my project seriously and I'm looking for the same kind of people.

Animated App Explainer Video

## Animated App Explainer Video – Nurture UAE We are looking for a talented **motion graphics / animation designer** to create a short, professional explainer video for our childcare app, **Nurture UAE**. ### About Nurture Nurture is an app designed to help parents and nannies/caregivers stay connected throughout a child's day. Parents and caregivers can share daily care updates, communicate through the app and access tools including activities, meals & recipes, learning resources and more. ### What we want to create We would like a **60–90 second animated explainer video** demonstrating how Nurture works. The video will be narrated by our existing owl mascot, **Nuri**. Nuri should become an animated character who **flies/moves around the screen, talks to the viewer and points towards different areas of the Nurture app interface** as they are being explained. We will provide the original Nuri mascot artwork and access/screenshots/screen recordings of the app. ### Example flow The video should demonstrate: **1. Parent joins Nurture** Nuri introduces the app while the Nurture interface appears on screen. **2. Connecting a caregiver** Show how a parent creates/connects their account and invites their nanny or caregiver to join their family. Nuri flies alongside the interface and points towards the relevant buttons/actions. **3. Daily Care** Show how the nanny can record things such as: • Meals • Naps • Activities • Photos • Mood/care updates And how the parent can see these updates during their day. **4. Messaging** Demonstrate parent–caregiver messaging and Nurture's translation functionality. **5. Activities** Show the activity section and how caregivers can find age-appropriate activity ideas for the child. **6. Meals & Recipes** Briefly demonstrate the recipe/meal features available to caregivers. **7. Nanny Learning** Show the learning resources available to help caregivers build their knowledge and skills. **8. Ending** Bring Nuri back prominently on screen alongside Nurture branding and a simple CTA: **Your child's day. All in one place.** **Download Nurture UAE – available on the App Store & Google Play.** ### Style we're looking for The finished video should feel **premium, modern, friendly and professional**. Nuri should add personality and warmth, but we don't want the video to feel overly childish. The primary audience is **parents of young children in the UAE**. We would particularly like someone who can combine: • 2D character animation • Motion graphics • App/UI animation • Screen recordings • Professional transitions • Voiceover/narration syncing • Sound effects/background music Nuri's existing design and colours **must remain consistent with our supplied mascot** rather than being redesigned or replaced with a generic AI-generated owl. ### Deliverables • Final 60–90 second explainer video • Vertical **9:16 version** for Instagram/Reels/TikTok • Landscape **16:9 version** for website/YouTube • High-resolution MP4 files • Animated Nuri mascot • Background music/sound design • Subtitles/on-screen captions • Source/project files where possible We can provide the Nurture branding, mascot artwork, app screenshots/screen recordings and guidance on the features that need to be demonstrated. ### When applying Please send examples of **app explainer videos, UI animations or character animation** you've previously created. If possible, please also explain how you would approach animating our existing owl mascot alongside screen recordings of the Nurture app. We're looking for someone who can take the concept and turn it into a polished, engaging video rather than simply assembling screenshots into a slideshow.

Business Development & Research

I am a Functional Medicine Health Coach, NLP/Transformation Coach and Group Strength Trainer based in Singapore. My work focuses on helping people improve their health through a root-cause, lifestyle and behaviour-change approach. I work with individuals, groups and companies, and I also deliver talks and workshops both online and in person on topics such as functional medicine, women’s health, energy, stress, sleep, gut health, menopause, mindset and wellbeing. I am looking for a freelancer to support me mainly with business development research. Key tasks would include: - Researching communities, clubs, networking groups and organisations that align with my target audience - Identifying potential partnership opportunities with practitioners such as physiotherapists, chiropractors, osteopaths, doctors, therapists and other complementary health professionals - Researching companies that may be interested in employee wellbeing talks or workshops - Identifying relevant HR, People & Culture, Wellbeing or Benefits contacts within those companies - Researching other speaking opportunities such as events, panels, podcasts, women’s groups and community organisations - Creating and maintaining a simple database of potential contacts, opportunities and follow-ups The main aim is to help me identify good-quality opportunities for partnerships, speaking and corporate wellbeing work, rather than broad generic lead generation. It would be helpful if you are confident with online research, organised, able to identify relevant contacts and opportunities, and comfortable working independently from a clear brief. Knowledge of the health, wellness or corporate wellbeing space would be useful but is not essential.

Earn Commission by Referring Shopify Store Owners to ScaleGuard

I am looking for Shopify freelancers, store managers, ecommerce consultants, Shopify VAs, developers, agencies, or anyone who works with Shopify store owners. I have built a Shopify app called ScaleGuard. ScaleGuard is an audit app that helps Shopify merchants identify issues before they spend more money on paid traffic. It checks product descriptions, catalog quality, product images, trust signals, fulfilment/delivery risk, store readiness, and paid traffic risk. The app is analysis-only. It does not change the store layout, theme, products, prices, descriptions, images, orders, customers, or settings. It only analyses the store and gives recommendations. The store owner must give permission before installing the app. During installation, Shopify may ask the owner to approve app permissions, including Orders access. This is used only for analysis purposes, such as understanding order activity, fulfilment/shipping patterns, and delivery-related signals. This is a commission-based referral opportunity. The offer for Shopify store owners: - First month free trial - No charge during the free trial - The store owner can uninstall before the trial ends if they do not want to continue - The app provides a store audit and recommendations Commission: - No commission during the free trial - If a store you refer becomes a paying ScaleGuard subscriber after the trial, you receive 50% commission for the first 3 paid months - Commission is paid only on actual subscription payments received - No commission is paid for fake installs, free trials, reviews, cancelled subscriptions, or stores installed without owner permission How it works: 1. You introduce ScaleGuard to a real Shopify store owner. 2. Before or when the store installs, you send me the Shopify store URL or myshopify.com URL. 3. I record the store as your referral. 4. If the store becomes a paying subscriber after the free trial, you receive 50% commission for the first 3 paid months. This is not a job for fake reviews or artificial installs. I am only interested in genuine Shopify store owners who may benefit from using ScaleGuard. If you work with Shopify merchants and want to earn commission by referring the app, please message me. Note: Please do not install the app on any client store without the store owner’s permission.

Google Console Keysign Mis-match

Not your usual mis-match, howerver. every time i try to upload my .abb i get get message: "Your Android App Bundle is signed with the wrong key. Ensure that your App Bundle is signed with the correct signing key and try again. Your App Bundle is expected to be signed with the certificate with fingerprint" So Google expects the B6 Key, I'm assuming the origanal one, which i don't have, find, and all this time Ive been using a B4 Key. which I think is from, stamped from Android Studio's kind of "throw away"-practice key , which is the B4. So see where Im coming from? & real key has never been used.,The last guy also said i had to replace the data inside my gradle dot someto possibly. IDK.. Pls, try to help me out, This is my "just for fun dream app, Im also a cancer patient(i'll send u proof if u want me to, I can't afford much, Pls, tell me one section at a time, I'll go and do it, then I'll return, and we do it this pattern again, I say this way if it's ok?

Finalize Flutter Media App Part-Time Flutter/Node Developer

Global Kirtan App (GKA) is a non-denominational platform for kirtan, sacred sound, and bhakti practice, built for a global audience spanning devotional practitioners, yoga communities, sound healers, and spiritual-but-not-religious users. It's a freemium mobile app combining regular practices, audio/video streaming, a lyrics library with translations, tutorials, event discovery (map + calendar), facilitator and community profiles, and an instrument shop. This isn't a from-scratch build. A working Flutter app already exists with a live backend, and it's been through an independent technical audit — we know its real strengths and its real problems. We're looking for a developer to pick it up from here. The Role This is deliberately not a full-time position, and we can't offer at this time. What we're looking for instead is someone willing to become our standing point of contact for this codebase — available reliably when work comes in, understanding upfront that hours will vary month to month and neither side is committing to fixed employment. If you need guaranteed steady hours, this probably isn't the right fit; if you're comfortable with an ongoing, flexible working relationship and want to be the person who knows this app inside out over time, it might be exactly right. There's no guarantee here — but a developer who proves reliable and becomes a genuine fit for this project would be our first call for full-time or expanded part-time work, once we're actually in a position to offer it. First phase — roughly 20 hours: • Fix the known issues from our existing audit. • Begin work on a new Practice tool — a planned addition to the app's core navigation. Full specification shared once we've agreed terms. After that — ongoing, unpredictable: • Common maintenance tasks • Bug fixes, small feature additions, dependency and security updates, as they come up • Some months will be quiet, others busier — we're looking for someone who can flex with that rather than needing a fixed retainer Compensation Compensation is set at Indian developer market rates. Whether we structure it as hourly or fixed-per-requirement will be decided together based on what makes sense for each piece of work — we're open to either. Confirmed Tech Stack Mobile app (Flutter/Dart): flutter_riverpod (state management), go_router (navigation), dio (networking), just_audio + audio_service (media playback and session handling), youtube_player_iframe (embedded video), flutter_map, flutter_secure_storage (encrypted credential storage). Release builds use R8 obfuscation and are properly signed. Backend (as specified): Node.js + TypeScript modular monolith, PostgreSQL, versioned REST API (/api/v1/), JWT-based authentication. What We Need From You • Real, demonstrable Flutter/Dart experience — ideally including audio or media-heavy apps • Comfort inheriting and working inside an existing codebase, not just building greenfield • Honest communication about your own actual availability — we'd much rather hear "I can only do a few hours some months" upfront than have someone overcommit and go quiet later • A genuine interest in an ongoing relationship with this project, not a single ticket — we're picking a person to grow with the app, not just closing a task • Comfortable working respectfully with devotional and sacred content across multiple traditions • Willingness to sign an NDA and assign IP (Intellectual Property) ownership of delivered work to us How We'll Work • Full Git repository access, normal commit/PR discipline • We'll share our existing independent technical audit with serious applicants (under NDA) so you know exactly what you're inheriting before committing to anything • Payment structure and rate agreed in writing before the first task begins To Apply, Please Share 1. Flutter/mobile projects you've built or maintained, especially anything involving audio/media playback 2. Your honest, realistic read on your own availability over the next 6–12 months 3. Any experience picking up and maintaining someone else's existing codebase (not just building your own)

I need RP voiceover of phonemes for a pronunciation app

Hi! I'm building a British English (RP) pronunciation-learning app and need a single native RP voice recorded for the app's sound library. I'm checking for standard Received Pronunciation specifically — no R sound in "rather"/"water" (non-rhotic), "bath" said with a long "ah" not a flat "a", a clear T in "water" (not "wa'er"), and the H in "have" kept in. If that sounds right, here's the job: About 380 short clips total: 88 isolated phoneme sounds (2 speeds each), 280 individual words, and 12 short phrases spoken at natural fast conversational speed Single voice throughout — one quiet room/session for consistency Delivered as WAV or M4A, 44.1kHz or higher I'll send the full word list and file-naming spec once we're ready to start recording This is for a commercial, paid app (subscription-based), not a personal project — so I need full commercial usage rights: a complete buyout of the recordings, work-for-hire, no royalties or usage caps, and no restriction on redistributing the audio inside a paid app. Please confirm upfront whether your standard rate includes that license or if a commercial buyout costs extra, so there are no surprises later. This could later lead to additional work if it were a success.
