    I want a clean, intuitive mobile app (iOS and Android) that lets users turn one or more photos into a single PDF while showing them a live “before vs after” file-size comparison. Each conversion spends coins. Coins can be bought through standard in-app purchases and can also be earned automatically when a user’s personal referral link brings in a new installer; there is no earn-by-usage mechanic. Because I have no artwork or wireframes yet, the full UI/UX still needs to be designed—from the first onboarding screen to the purchase flow. Once the look and feel are approved, the same team should build the production-ready app, integrate Apple/Google payment gateways for coin packs, and implement a secure backend that tracks balances and referral bonuses in real time. ...

The first public build must run smoothly on both iOS and Android so I can start live market testing as soon as possible. Core flow A rider requests a trip, proposes a price, the driver can counter, and once both sides accept the “fair fare,” the ride is locked in. From there the experience should feel familiar to any on-demand service: real-time location sharing, start/finish tracking, and automatic ride history logging for both accounts.

    I want to create a light-hearted mobile app that works on both iOS and Android and feels similar to the classic Talking Tom experience. The main attraction is voice interaction: when a user speaks, a fun on-screen character should immediately listen, modify the pitch, and play the line back while lip-syncing. Scope and expectations • Cross-platform build delivered as two store-ready packages (App Store and Google Play). • One animated character asset is enough for this first release; I am fine with a placeholder as long as the animation and mouth movement sync convincingly with the audio. • Real-time voice capture, processing, and playback with a cartoon-style pitch shift. • Basic UI: record button, replay, and a simple share option for the recorded clip.

    I need a dedicated mobile app that puts cooking tutorials front and centre. The core of the build is an intuitive, visually engaging interface where users can browse, watch and save tutorials—whether they’re learning knife skills or mastering full dishes. Key requirements • Native-quality performance on both iOS and Android (React Native or Flutter are fine; I’m open to another modern framework if it delivers the same fluid experience). • A searchable tutorial library organised by cuisine, skill level and prep time. • Smooth video playback with the option for future expansion into text or live-session formats. • Favourites and progress tracking so users can pick up where they left off. • Push notifications for new lessons or seasonal re...

    I’m building a cross-platform mobile app that helps users stay organized and in sync across iOS and Android. The core of the project is a productivity tool, so clean UX, quick load times, and rock-solid data handling matter as much as the code itself. Key features I must see in the first release: • Task management – users can create, edit, prioritise, and mark tasks complete. • Calendar integration – events flow in and out of the native calendar APIs with two-way sync. • User collaboration – real-time sharing of tasks and deadlines between team members. I’m happy for you to work with React Native, Flutter, or another proven cross-platform framework; just outline your preferred stack and why you like it. Clean, well-commented code stored in...

    I have a working prototype sitting inside Google’s AI Studio and now need it promoted to a production-ready mobile application, released on both iOS and Android, and fully hosted on Google Cloud Platform. The core model logic is already proven; what’s missing is everything around it: a clean mobile front-end, user flows, GCP infrastructure and a reliable release pipeline. The finished apps must support in-app purchases from day one so users can unlock premium features straight from the App Store and Google Play. Here’s what I expect to come out of the engagement: • Source-controlled Flutter or React Native codebase (or another proven cross-platform stack you can justify) wired to the existing AI Studio APIs. • GCP backend configured for production &ndash...

    I have a cloud-based Digital Signage Management Platform built with Flutter, Firebase, Firestore and Firebase Storage. The core features—admin dashboard, campaign and playlist scheduling, multi-screen remote control, and an Android TV player—are already live (you can preview the current demo at ). The next development phase is all about polish and stability, and my first priority is crystal-smooth video playback. Right now videos lag or buffer and certain streams don’t behave consistently on Android TV devices. Because the system displays both videos and images in rotation, even a momentary stutter is noticeable on-screen, so I need someone who knows exactly how to squeeze every drop of performance from Flutter’s rendering pipeline and from Firebase’s media...

    The goal of this feature is real-time wellness monitoring during biometric attendance logging. The AI must accurately classify a user's face into three specific categories: Happy, Neutral, Stressed, Surprised, Feared, Sad(mapping tensed brows, eye strain, and lip tightening). We want 100% accuracy in identifying emotions.

    The project is an end-to-end food-ordering solution that must run natively on both iOS and Android. The core flow covers standard restaurant meals as well as a daily “Our Rasoi” tiffin section, so the codebase should let me manage two menu streams from the same backend. Key app functions • User profiles that store addresses, dietary preferences, and past orders. • Real-time tracking from kitchen dispatch to doorstep. Users should see a live driver map along with status push notifications. • Multiple payment options, including cards, UPI, wallets, and COD. Payment tokens need to be saved securely for one-tap reorders. Tiffin-specific layer Subscribers choose a plan (weekly, fortnightly, monthly), customise each day’s meal, and set or change their...

    I’m building a small, family-focused rent tracker and I want it coded in Flutter for Android. The app should run perfectly offline, then sync or back up when I trigger it, so my data is never tied to a cloud account I don’t control. Core flow – A straightforward e-mail-and-password login lands me on a modern, clutter-free dashboard. – I can add a shop or store, register each tenant, set the monthly amount, and let the app compute anything still pending. – Agreement dates trigger expiry reminders automatically. – One tap generates a PDF receipt; another exports the full data set to Excel or PDF. – I can back up the entire database, then restore it on a new phone without losing a thing. Reports I need regularly: • Monthly summaries...

    I purchase complete projects from Codecanyon and need each one put into production quickly and cleanly. Your job is straightforward: • Deploy the admin panel exactly as the author documents—no deep code changes, just follow the guide, connect the database and point the domain. • Apply my colours, logo and other branding assets so the back-office and app reflect our identity. • Build the Android app from the same source, generate the signed AAB and publish it in my Google Play console. That flow will repeat for multiple projects every month, so I’m looking for someone who values speed, accuracy and clear communication. If you already work comfortably with typical Codecanyon stacks (Laravel / PHP, Flutter or React Native builds, Firebase push, etc.) you&r...

    I’m building a mobile app that must launch on both iOS and Android from a single code-base. Beyond the usual screens and navigation, the first essential capability is reliable push notifications wired to a modest back-end, so users receive timely updates even when the app is closed. I’m looking for one developer who can own the whole stack: architect the database and APIs, craft a clean front-end UI, stitch everything together, deploy to the stores, and document the process so future updates are straightforward. Modern cross-platform frameworks (React Native, Flutter or similar) are welcome as long as the final binaries pass App Store and Google Play review without extra re-work. Deliverables: • Production-ready iOS and Android builds • Push notification service f...
