    I’m experimenting with the full development workflow on Freelancer, so I’d like a modest proof-of-concept mobile app that I can study and extend later. The app must compile for both iOS and Android and include three working features from the start: secure user authentication, standard push notifications, and a placeholder in-app purchase flow. Here’s what I need at the end: • A clean, well-commented codebase (React Native, Flutter, or another cross-platform framework you prefer) that builds on current Xcode and Android Studio releases. • A short README explaining environment setup, build steps, and where each of the three features lives in the code. • Demonstration videos or screenshots that verify login, a test push notification, and a mock purchase...

    I have a fresh concept for a productivity tool and nothing more than a set of sketches and feature notes, so I’m looking for a developer who can turn this idea into fully released apps on both iOS and Android within roughly a month. You’ll need to guide the whole lifecycle: refining the feature set, choosing the optimal tech stack (Flutter, React Native, Swift/Kotlin—open to what fits best), designing a clean UI/UX, building any required backend or cloud functions, testing, and finally submitting to the App Store and Google Play. If you’re comfortable owning everything from architecture to deployment and can move fast without sacrificing reliability, we should talk. After an initial NDA I’ll share wireframes, user flows, and the detailed roadmap so we ca...

    I already have a partially built mobile productivity app and I need an experienced developer to bring it to completion for both iOS and Android. The core idea and initial code are in place; what remains is polishing the interface, wiring up the remaining features, tightening performance, and pushing the app through final testing and store submission. You’ll be working with the existing repository (I’ll grant Git access as soon as we start) and a clear feature list that shows what is done and what still needs attention. Expect tasks such as: completing a few unfinished screens, integrating the last API endpoints, resolving bugs flagged in the current test build, and making sure the UX feels equally smooth on iOS and Android devices.

Camera reads the PDF417 barcode on the back of a customer’s US or Canadian driver license. 1a. Camera reads a picture of the front of the drivers license so we have their picture. 1b. Infrequently, the customer has a foreign passport and not a DL so we will need some way to manually enter information in that case. It is VERY infrequent, but it needs to be there. 2. Parsed data auto-fills a fixed liability PDF form (name, address, DL number, expiry, etc.) which we will supply. 3.

    I have an existing iOS tracking application that is almost ready for the App Store, but a few critical pieces still need attention before I can ship. The main blocker is unreliable user-activity tracking. Data occasionally drops or shows incorrect session times, so I need that flow audited, patched, and thoroughly tested. At the same time, real-time location updates lag behind by several seconds. I want you to optimise the Core Location stream (or any alternative you recommend) so the map view and background updates stay genuinely live throughout the day. Profile management also needs a quick sweep: make sure every profile edit instantly reflects across tracking, history, and reports. For notifications, I’ve decided to keep everything inside the app; please implement clean, non-i...

At this stage I am deliberately keeping the brief minimal because the goal is to evaluate your approach, code quality, and communication style before we move on to a full build. Here is what the first milestone should demonstrate: • A clean data model able to store individual apple entries (feel free to invent a few sample fields such as variety, harvest date, or quality score so I can see relational thinking). • A simple screen that lists the saved records and lets me add a new one. • Clear, commented source code plus a short read-me describing the architecture and any third-party packages you introduced.

Project scope & deliverables – Responsive e-commerce website connected to a secure backend (language, framework and CMS are your call as long as it’s scalable). – Nati...

    Saya membutuhkan sebuah aplikasi mobile sederhana yang bisa dijalankan di iOS dan Android. Fokus utamanya hanyalah modul Login pengguna—cukup layar masuk, pendaftaran, dan lupa kata sandi yang terhubung ke API sederhana (REST atau GraphQL). Silakan gunakan pendekatan native maupun cross-platform (Flutter, React Native, atau sejenisnya) asalkan hasil akhirnya stabil di kedua platform. Deliverable yang saya harapkan: • Kode sumber lengkap dan terstruktur • Berkas build/arsip siap rilis untuk App Store & Play Store • Dokumentasi singkat cara menjalankan proyek secara lokal dan cara mengganti endpoint backend Saya akan menilai proyek berdasarkan kemudahan build, kejelasan struktur kode, dan kelancaran proses login.

    All screens, flows, and assets for my medical-health app are already laid out in Figma; what I need now is the full build—iOS, Android, and the backend that ties them together. The scope covers everything from setting up user authentication through to submitting the binaries to the App Store and Google Play. Along the way the app must hook into three key integrations I’ve planned: • Payment gateways for subscription and one-off charges • Health data APIs so users can sync with Apple HealthKit / Google Fit out of the box • A real-time messaging system that supports secure in-app chat and push notifications I’ll share the complete Figma file plus a short functional spec the moment we kick off. Pixel-perfect implementation is important, but so is soli...

    I need a straightforward yet reliable solution that lets me run several clinics from a single platform. Core workflow starts with a patient entry form that captures demographics and immediately opens a running history for each record. The history must log their medical conditions, previous appointments and current or past medications without fail; every new visit simply appends to that timeline so nothing is lost. Bookings will be handled through a list-view appointment module—speed is more important than a visual calendar—so staff can scan, add or modify slots quickly. Because the group owns more than one location, the system should recognise which clinic a booking belongs to and allow easy reassignment if a patient switches branches. On the mobile side I want companion apps...

    I need a seasoned iOS engineer to wire full Stripe support into my Swift-based app. Your task covers both sides of the fence: • In the app: build clean, production-ready flows for payment processing and payouts using Stripe’s latest iOS SDK. The UI is already in place; hooks for card entry, Apple Pay and instant payout status simply need reliable Stripe logic behind them. • On the server: stand up a small, well-structured Node.js backend (Express is fine) that handles customer creation, payment intents, webhook handling, and payout scheduling. The mobile client should talk to it through lightweight, documented endpoints and all secrets must remain server-side. I’m interested in developers who have shipped several Stripe-to-iOS integrations before and can point me t...

    I need a straightforward mobile app that runs smoothly on both iOS and Android. Its core job is to let me record every ice sale in seconds: • I select (or add) a customer and their pre-saved price per 1 kg, 3 kg, and 5 kg bag auto-fills. • I type the quantities sold and the app instantly shows the line total and the grand total. • At any moment I can open a dashboard that sums all sales: one view groups them by day, another rolls them up by calendar month. A small back-office screen must let me: – create, edit, or deactivate customers and their individual price lists; – correct any mistaken sale; – back up or export the raw table (CSV or similar). I’m open to your suggestion on the underlying data store—MySQL, SQLite, Firebase, or a...

    I want a simple, reliable mobile application that lets me capture, organise and complete my daily tasks wherever I am. The app must run smoothly on both iOS and Android, so a cross-platform framework such as Flutter or React Native makes sense, but I am open to your preferred stack as long as the final binaries install cleanly on recent devices. Core workflow • Add, edit, reorder and delete tasks in as few taps as possible. • Optional due date and reminder notifications so I don’t miss deadlines. • Visual status cues (e.g. colour or strike-through) for completed items. • Local data storage with an easy export or backup option; no server back-end is required at this stage. Deliverables • Source code and project files. • Test builds (.ipa for...

    The design files are final; now the UI must look just as flawless on devices as it does in Figma. I need every pixel, font weight, and micro-interaction implemented in Flutter so the mobile app behaves identically on both iOS and Android. Responsiveness across screen sizes, smooth 60 fps animations, dark-mode readiness, and adherence to Material / Cupertino conventions where appropriate are all part of “perfect” for me. Because this project is a UI build only, clean, well-commented Dart code and a clear folder structure are essential—I want to be able to hand the repo straight to the backend team without a refactor. Continuous delivery through Git (one small merge request per screen) will help keep review cycles short, and I’m ready to begin those reviews immediate...
