I’m building an end-to-end healthcare application that blends AI-driven diagnostics and analysis, robust patient-management features, and forward-looking predictive analytics. The system must learn from three primary data streams—electronic health records, medical imaging, and genetic information—while remaining HIPAA-compliant throughout the pipeline.

I want an app that helps golfers record and analyse their swing on both iOS and Android phones. The core of the project is accurate, frame-by-frame swing analysis: the user opens the camera inside the app, captures a swing, and then sees clear visual feedback—slow-motion playback, key angles highlighted, and comparison with previous swings stored locally on the device. A clean, intuitive interface is important; users should reach the analysis screen in as few taps as possible and scrub through the video smoothly. I am open to whichever stack you feel delivers the best real-time performance—native Swift/Kotlin, Flutter, or React Native with the right camera and computer-vision libraries—but please outline your choice and why it suits this specific task. If you have an off...

I need a fully-async Python 3.11+ pipeline that turns a live phone call into a smooth, sub-2.5 s p50 conversational loop. Here’s the flow I have in mind: a Twilio SIP trunk delivers the RTP stream to a WebSocket bridge; LiveKit Agents SDK manages the media session; Deepgram Nova-3 handles streaming STT; the running transcript feeds Claude (with tool-use enabled); Claude’s text comes back out through ElevenLabs Flash v2.5 for TTS and streams to the caller in real time. What I need from you is a working reference implementation, instrumented and tuned so I can see latency at each hop and fine-tune Voice Activity Detection thresholds. The code must retry transient errors, log everything that matters, notify the caller gracefully on trouble, and, if the Sonnet tier fails mid-call...
I’m working with a few Android gaming titles and need hands-on help turning each one into a working modded APK, then getting those builds to run reliably in BlueStacks. While I haven’t locked in any specific premium unlocks or UI tweaks yet, the goal is to understand the entire packaging process so I can apply future changes myself. Once the APKs are ready, I also need BlueStacks configured to launch several instances of the same game at once. Smooth performance, hassle-free installs, and clear account separation matter most to me. What I’m expecting from you • A repeatable workflow (using Apktool, Android Studio, or any proven tools) that produces a signed, install-ready modded APK for the chosen games. • Step-by-step guidance—live or documented&mdash...

Create an app which supports people to create photos suitable for an identification document. The app will interact with a server and has the following high-level functionality: • The user takes a photo. • The app sends the photo to the server which checks the photo, the app communicates the results of the photo check to the user. The user can decide if he wants to take another photo or if he wants to continue. • In case the user continues, the “Final Processing” starts. The final processing step removes the background from the image and verifies purchase data. The app has a free and a premium option. For the premium option, the user can buy in the app credits (in app purchase). If the user has premium credits, he will receive a full resolution photo. Otherw...
I need a clear, actionable blueprint for building a sales-focused e-commerce mobile app that will launch on both iOS and Android. The document should guide my in-house team from concept to store release, showing exactly how we can weave AI into the user journey to boost conversions and lifetime value.

Hem iOS hem de Android’de çalışacak, harita odaklı bir mobil uygulama yaptırmak istiyorum. Uygulama canlı konum takibi yapacak, rota planlayacak ve kullanıcıya yakındaki yerleri gösterecek. Ayrıca uygulama içi satın alma sistemi de yer alacak; şu an için abonelikler ve tek seferlik satın almalar tanımlanacak.

I am launching a mobile app that lets shoppers see participating store locations on a live map, check-in when they walk through the door, and instantly invite friends from their phone contacts to join them. When an invited friend shows up, the store grants that friend an on-the-spot discount while boosting the reward balance of the person who sent the invite—turning every visit into an easy referral loop. The build needs to run natively on both iOS and Android from a single codebase. Phone-number verification will be the only sign-in method, so please factor in an SMS OTP flow. For mapping and in-store positioning I want Google Maps SDK with smooth zoom, pin clustering, and real-time distance calculations. Stores will appear, the user taps “I’m here,” and the app r...
I’m building an Android-only mobile application that will serve members of our Nubian Club. The core experience should let users create an account (email, phone, or social login), sign in securely, and then: • Browse upcoming club events, RSVP, and receive reminders through a simple event-scheduling module. • Log and review participation in regular activities—think step counts, training sessions, or volunteer hours—so members can track personal progress and see club-wide leaderboards if possible. A clean material-design interface, smooth offline handling, and a lightweight backend (Firebase, Supabase, or an equivalent that you recommend) are preferred. An admin console to add or edit events and pull activity reports will make management easier, but it doesn&...
I need my Android application installed on ten separate devices and used continuously for a full-two-week period. I’ll supply the play store link; all you have to do is sideload it, run through normal day-to-day interactions, and note anything that affects ease of use. The focus is strictly usability, so I’m interested in first-time impressions, navigation flow, clarity of labels, and any pain points that slow you down. No performance metrics or deep functional debugging is required beyond what you naturally notice while using the app. Deliverables • Proof of installation on 10 unique Android devices (model + OS version screenshots) • A concise daily log highlighting what tasks you attempted and any confusing moments or UI friction you encountered • A fin...
About the project We've built , a SaaS platform that acts as a middleware layer between users and the Anthropic Claude API. Users provide their own Claude API key, and our backend processes requests through proprietary infrastructure designed to reduce token consumption. We're pre-launch and need thorough third-party QA before opening to paying customers. ***PLEASE GO THROUGH ENTIRE SIGN UP PROCESS A - Z*** What we need tested 1. Functional testing (all user flows) Signup, login, password reset, session handling API key submission, encryption at rest, and deletion flows Credit purchase flow across all three tiers ($10, $25, $50) and custom amounts End-to-end request flow: user prompt → our backend → Claude API → response Streaming, tool use, and vision request h...
I need a complete rideshare solution built from the ground up for both iOS and Android. The core flow is familiar—riders request, drivers accept, trips are tracked in real time—but there are a few extras that are non-negotiable: • Third-party booking: a user must be able to schedule and pay for a ride on someone else’s behalf. A common use case will be parents arranging rides for their children. • In-app texting: rider ↔ driver, plus system notifications, all stored for audit. • PayPal checkout: for now that is the only payment rail we’ll launch with, so make sure the integration is production-ready and PCI-compliant. • Centralised user store: one secure database that holds drivers, riders, and parents with clearly differentiated role...
I’m ready to turn my idea for a brand-new social networking mobile app into a working product. The concept centres on giving users a clean, intuitive space to create profiles, connect with friends, share posts, and exchange real-time messages. I already have the core feature list sketched out and initial wireframes for the main screens. What I need now is end-to-end development: architecture planning, UI implementation, secure user authentication, database integration, and the polish that will make the experience fast and reliable. I’m flexible on the tech stack—whether you prefer native iOS/Android builds or a robust cross-platform framework, let’s agree on the approach that guarantees smooth performance and future scalability. Deliverables • Complete ...
I’m building a focused numerology app whose single goal is to calculate core numbers accurately and present them in a clean, mobile-friendly interface. The app must handle Life Path Number, Destiny Number, Personal Year, the classic Pythagorean Arrows, and the Yantra grid. No elaborate user accounts are necessary—just collect the basic details (name and date of birth) in one step and run the calculations on-device so results appear instantly. Key expectations • Intuitive input screen that validates name and birth-date formats • Well-documented calculation engine covering the five items above • Results page that shows each number or pattern with a brief one-line label (readings and daily tips may come later, so keep the UI modular) • Lightweight data...
I’m ready to move from concept to code for a full-featured appointment booking application built entirely with Flutter. The app will serve three distinct roles—Admin, Service Provider, and Customer—each with tailored dashboards and permissions. Core functionality I need: • Seamless calendar integration so providers can set availability and customers can see real-time slots • Secure payment processing at checkout (Stripe or a comparable gateway) • Push and email notifications for new bookings, changes, and reminders I’ll share a detailed reference app and brand guidelines once we agree to collaborate, and I’m happy to refine the scope together before sprint planning. Your deliverable will be a production-ready Flutter project (iOS, Androi...

I am building a social e-commerce platform tailored to the Indian market and I’m ready to bring on a technical co-founder who can own the entire mobile product. Your primary focus will be end-to-end app development for both iOS and Android—choosing the right stack (whether that’s React Native, Flutter, or fully native) and leading it from an MVP to a scalable, production-ready release. You’ll work shoulder-to-shoulder with me on product strategy, feature prioritisation, and user experience, then translate those ideas into clean, maintainable code. As a true co-founder you will help shape technical architecture, assemble an engineering team as we grow, and share in the startup’s equity upside rather than taking a traditional salary. If you love crafting mobil...
I need an Android-only camera application that automatically embeds the current GPS coordinates into every shot—whether I’m taking a high-resolution photo or recording a full-HD (or better) video. In addition to the geo-tag, the app must add a watermark that can combine custom text with my logo on the final media file. I should be able to adjust basic settings (watermark position, size, opacity) quickly before capture, but the location capture itself must be hands-free and precise. Core deliverables • APK (and source) that opens directly to the camera preview. • Instant capture of latitude, longitude, and optionally timestamp, stored in EXIF for photos and in metadata for videos. • Real-time overlay rendering so I can confirm the watermark and location bef...
The immediate goal is to deliver a highly secure escrow app for both iOS and Android that handles P2P, B2B, P2B and B2P transactions right out of the gate. Bank-grade encryption, a strict zero-trust architecture, and full OWASP compliance are non-negotiable pillars of the build. Phase 1 – Mobile First • Design and code the core escrow workflow for peer-to-peer and business-to-business payments. • Implement strong customer authentication, role-based access, and end-to-end encrypted data at rest and in transit. • Integrate a modular backend API so we can later expose the same services to a web portal and USSD interface without rewriting business logic. Security & Compliance Every line must pass automated OWASP checks, static code analysis, and peer revi...
I’m building a focused utility app for Android and want the entire project written in Flutter so I can maintain a single, clean codebase going forward. I’ll share wire-frames, detailed user flows, and any server-side API once it’s finalised; your job is to turn that material into a polished, lightweight application that feels entirely native on modern Android devices. What I expect from you • A well-structured Flutter project that compiles into a signed APK/AAB ready for Google Play submission • State management implemented with Provider, Riverpod, or a comparable modern solution • Smooth handling of permissions, small-footprint analytics, and in-app update checks • Clear hand-over notes and build instructions so I can keep iterating after r...
I am building a full-scale electric-vehicle mobile app whose first milestone is a robust Charging Station Locator. The product will roll out on iOS and Android, so I will need both the customer-facing front end and the cloud-hosted back end designed, coded, tested, and released over the next six months. You will take ownership of: • Front end: map view, search & filter, live availability indicators, account/login screens, and smooth UI animations. React Native or Flutter are both acceptable; clean, maintainable code is essential. • Back end: scalable REST/GraphQL APIs, real-time database (Firebase, Supabase, or similar), geospatial queries, user auth, and an admin dashboard for station data maintenance. • DevOps: CI/CD, staging & production environments, sto...

I need a single mobile application that runs smoothly on both iOS and Android and pairs with an ODB-II Bluetooth dongle. Once connected, the app must read live vehicle data, pull stored error codes with human-readable descriptions, and generate maintenance reminders based on mileage or running hours. Connection should happen automatically as soon as the phone detects the paired dongle; no manual VIN or parameter entry is expected. For users who prefer it, the same information can be imported from an existing test report file, so I’ll need a simple file-picker flow that parses that report and displays the results exactly as if they came from the live Bluetooth session. All customer details—name, contact info, vehicle profile, past scans—stay inside the app’s ow...

I have three production-ready Android apps waiting to go live on Google Play. All APKs (plus icons, screenshots, descriptions, privacy policies and signing keys) are finished; the only step left is getting each one accepted in the Play Console and visible to users. Because I do not hold a Google Play Developer account and don’t need assistance opening one, I’m looking for someone who already has an active, compliant Play Console and can handle the entire submission process on my behalf. This includes creating the store listings, uploading the bundles, setting the correct content ratings, turning on Data Safety, configuring releases (production only), and making any small text or asset adjustments Play might require to secure approval.
