Mobile App Development Projects

Get some sales through app store and Google play store.

We had an app designed a year or so ago... I (think) it is live on the google play store and the Apple Store, but I'm not even totally sure whether or not it is actually live - there have been absolutely no sales through it at all, which is probably very unusual. I am looking for someone to;- 1. Double check that it is actually live on teh play store and the Apple Store. 2. If it's not live, fix it. 3. Promote it somehow (we don't have a budget for this) so that it gets some sales.

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.

Customer Portal, Mobile App

# Tender Brief – Customer Portal, Mobile App & EPOS Integration ## Project Overview We are a multi-site second-hand retail business operating a buy, sell and buyback model. We are looking for an experienced software development partner to create a digital customer platform that integrates with our existing .NET EPOS system. The project should include: * Customer website portal * Digital customer agreements * Buyback and renewal functionality * Online payments * EPOS integration * iOS and Android mobile app * Customer reminders and notifications ## Customer Portal Customers should be able to: * Register and log in securely * View current and previous buyback agreements * View agreement expiry and renewal dates * Renew eligible agreements online * Make required payments * View and download agreements * View relevant transaction history * Receive account notifications and reminders The website should be mobile-first and simple to use. ## Digital Agreements The platform should create customer agreements using transaction data held within our EPOS.

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)

Mobile quiz app

Hi, I'm a carpentry and joinery lecturer teaching City & Guilds 6706 across Levels 1–3 plus apprentices, and I'm looking to build a simple quiz/revision app for my students. The idea: a mobile-friendly practice test app, similar in style to driving theory test apps, covering the knowledge modules for the 6706 qualification (first fix, second fix, roofs, stairs, bench joinery, etc). Core features I'd need for a first version:Question bank organised by module/topic Multiple choice format with instant feedback/explanations Timed mock exam mode Basic progress tracking per user A simple way for me to add/edit questions myself without needing a developer each time I'd like to start with a lean, low-cost first version (web app or simple cross-platform app) to trial with my own students before considering a bigger build. My budget for this initial version is around £2,000–£5,000. Could you let me know:Whether this is something you'd be able to help with Roughly how long it would take Examples of similar quiz/test apps you've built before Thanks, Andy

Remaining Work I would like an experienced developer to review the existing codebase and estimate the work required to bring the application to a reliable production-ready version. Expected remaining work may include: Backend & Accounts * User authentication * User/company accounts * Cloud database * Cloud storage * Data synchronisation * Backup/recovery * Multiple projects per user/company AI & Automation * AI-assisted report generation * OCR for delivery notes/documents * Speech-to-text improvements * Translation improvements * Automated summaries Reports * Final PDF layout improvements * Company branding/logo support * Reliable PDF export * Sharing/email functionality Mobile Application * Preparing the existing application for mobile deployment * iOS support * Android support * Testing on real devices * Performance optimisation * Offline/poor-connection considerations Production Readiness * Security review * Data protection/privacy requirements * Account/data deletion * Error handling * Production database configuration * App Store preparation * Google Play preparation * Final testing and bug fixing What I Am Looking For At this stage, I am particularly interested in receiving a realistic technical assessment and quotation. Please provide: 1. Your estimated number of development hours required to complete the project. 2. Your hourly rate and/or fixed-price estimate. 3. Estimated completion time. 4. Which parts of the existing application you would keep or rebuild. 5. Any technical problems or risks you would expect. 6. Recommended backend/cloud architecture. 7. Your experience with React/TypeScript, mobile apps, AI APIs, OCR and PDF generation. 8. Whether your quotation includes App Store and Google Play submission. 9. Examples of similar business applications you have completed. Important I am not looking for a complete rebuild unless there is a strong technical reason for doing so. The objective is to use the existing application and codebase wherever practical and bring it to production standard. The application will initially be tested by real construction Site Managers before wider commercial release. Please base your proposal on completing and improving an existing working application, rather than estimating the cost of developing the entire product from scratch. I am happy to provide additional information, screenshots and access to the existing codebase to shortlisted developers after initial discussions. Please explain briefly how you would approach the project rather than sending a generic proposal.
