User Authentication & Profiles Sign-up/Sign-in via Email, Google, and Apple ID. User profiles displaying "Trust Score," "Level," and "Total Tokens." Streak tracking (e.g., 0-day streak) to encourage daily engagement. 2. Interactive Map Interface (Core Feature) A real-time map view (Google Maps or Mapbox integration). Visual "pins" based on the category of the encounter. Filter system to toggle visibility of different pin types (Karen, Chad, etc.). "Current Location" centering and search functionality. 3. Encounter Reporting ("Add Pin") User-friendly form to submit encounters. Categories: Karen: Annoying or entitled behavior. Chad: Positive or funny encounters. Legend: Wholesome or helpful encounters. Warning: Scams, safety alerts, or warnings. Submission Details: Title, Description, Category selection, and Geo-location (automatic or manual). 4. Moderation & Pending System All submitted pins must go to a Pending Queue. Admin/Moderator capability to review, approve, or reject pins before they appear on the public map. A "Pending" tab for users to track the status of their submissions. 5. Gamification & Leaderboard Token System: Users earn tokens for approved pins. Trust Score: A leveling system (Level 1, 2, etc.) based on the accuracy and frequency of reports. Leaderboard: A dedicated "Board" tab showing top users ranked by Tokens, Trust, or Activity. 6. Categorized Feeds Dedicated tabs for "Karen Sightings," "Chad Encounters," "Nice Legends," and "Warnings." Feeds should include "Most Reported" trends for the week (e.g., "Most reported: Phone scams this week"). Technical Requirements Platform: Cross-platform development (Flutter or React Native) to ensure 100% feature parity on iOS and Android. Backend: Firebase (Firestore, Auth, Functions) or a Node.js/PostgreSQL setup. Geolocation: Deep integration with GPS and mapping APIs. UI/UX: I have existing high-fidelity wireframes/screenshots. The developer must be able to replicate the clean, modern aesthetic shown in the designs (rounded containers, soft shadows, and specific iconography). Timeline & Milestones Phase 1: Backend setup & User Authentication. Phase 2: Map integration & Pin submission logic. Phase 3: Admin Moderation panel & Pending flow. Phase 4: Gamification (Tokens/Leaderboards). Phase 5: QA Testing & Deployment to App Store/Google Play.

Android Employee Activity Keylogger

I need a discreet Android application that records employee device activity for compliance purposes. The app must log every keystroke, track websites visited in any browser, and chronicle foreground app usage with accurate timestamps. At user-defined intervals these three data streams should be consolidated into a clear report and sent automatically to a chosen email address. The service has to survive reboots, remain hidden from casual discovery, and run smoothly on Android 9 through 14 without demanding root access. Battery and data consumption should be minimal. A single first-run screen where I can enter SMTP credentials, reporting frequency, and perhaps an optional keyword filter is sufficient—after that, the interface can vanish. Deliverables • Release-ready APK plus fully commented source code • Straightforward setup guide suitable for a non-technical manager • README detailing the permissions used and collection methods Acceptance criteria • Keystroke, website, and app-usage logs arrive via email on schedule with correct timestamps • No visible notifications or icons after initial configuration • Service restarts automatically after a reboot or update
