I’m launching an online school and need a complete platform—both a responsive website and a companion mobile app—that lets me teach live video classes. The classroom experience must include an interactive whiteboard, screen-sharing capability, and a live Q&A chat so I can engage with students in real time. Students have to be able to create an account, verify their email or phone, and sign in securely before joining a session. From there they should see upcoming classes, enter the live room at the scheduled time, and interact with the tools mentioned above. Deliverables • Website front-end and back-end ready for production • iOS and Android app built from the same codebase or native, as you prefer • Secure user registration and authentication flow...

I want to turn my current WordPress site into fully functional mobile apps for both the App Store and Google Play. The overall branding can stay, but the in-app layout needs to improve for small-screen use: • Navigation menu – simplify the hierarchy so users can reach the most important sections with fewer taps. • Homepage structure – reorder or redesign the hero section and featured blocks to highlight fresh content first. Once those two areas look and feel right, everything else can mirror the website. Deliverables I expect 1. Production-ready iOS and Android builds, created with the framework you prefer (WebView, Flutter, React Native, etc.) and signed for store submission. 2. Source code or project files (Xcode workspace, Android Studio project, or equiva...
I run a database-driven WordPress site and now need the same experience packaged neatly for both iOS and Android. The app must allow users to sign up, log in, manage their profiles and view all content that currently lives on the website. Every screen can assume a live internet connection, so there’s no need to cache large sections for offline use. I already have the WordPress REST API exposed, along with custom endpoints for user data, which you’re welcome to extend if that makes development smoother. A clean, native-feeling interface is important, but I’m flexible on whether you build natively or with a cross-platform framework such as Flutter or React Native—whichever lets you deliver a smooth experience without sacrificing speed. Key points you should cover in...

I need an experienced developer who can take a mobile app from concept to App Store and Google Play release. The core requirement is that the same code-base (whether React Native, Flutter, Kotlin Multiplatform, or another robust solution) delivers a smooth, fully native experience on both iOS and Android. Here’s the high-level flow I have in mind: • Collaborate with me to refine the feature list and user journeys. • Produce Figma or similar wireframes so I can sign off on the UX early. • Build the front-end and any necessary back-end or API integrations. • Handle rigorous device testing, performance tuning, and App Store / Play Store compliance. • Package and submit final builds, then provide post-launch support for any critical fixes. Code must be...
I already run a fully-responsive brochure website in English and Arabic that serves only text and images. What I now need is a very light native wrapper that opens the existing site inside a WebView on both iOS and Android, with a few essentials layered on top: • Manual language selection must remain available exactly as on the site. • Push notifications have to be integrated and tested end-to-end (Firebase / OneSignal or your preferred solution) so I can broadcast updates to users. • All store-side tasks—building signed binaries, preparing metadata in English and Arabic, submitting, handling review feedback, and getting the apps approved—are part of the scope. • After publication, you will keep the apps up-to-date and compatible with OS changes for a...

I need a full-featured mobile application that lets amateur football players and team managers find, book, and pay for match slots from the same interface. The product must launch simultaneously on iOS and Android; I am open to either native builds or a cross-platform stack such as Flutter or React Native provided performance feels native and the UI follows each platform’s guidelines. Two distinct user roles will sign in: players arrange casual games, while team managers organise fixtures for their squads. Both roles access the same core flow—choose a venue and time, confirm the booking, then pay—yet each sees role-specific screens (for example, a manager can reserve for an entire roster, whereas a solo player only books a slot). Key functions to include • Real-tim...
I’m ready to turn a simple idea into a polished mobile product: an app that lets people record every cup of coffee they drink throughout the day. I need it built natively for both iOS and Android, sharing as much code as practical (React Native, Flutter, Kotlin Multiplatform, or another modern cross-platform stack you’re comfortable with). Core feature the first release must cover: • Daily coffee intake logging Users will enter each drink manually, so the interface should open straight into an “Add cup” screen with fields for size, brew type, and optional notes. A clean dashboard should then sum today’s cups and show a running history by date. I’ll supply branding assets and a basic wireframe; you’ll handle UI refinement, development, local...
I want to release a simple, calm-looking mobile app that automatically marks the Sabbath for any user, anywhere in the world. From Friday dusk to Saturday dusk— with an optional setting that carries through to Sunday— the app should detect the local sunset (GPS or manual timezone entry), pop up a gentle reminder to set the phone aside, start a visible countdown clock, and finally display a Biblical verse when the time is complete. Both iOS and Android builds are needed, preferably with a shared codebase (React Native, Flutter or a lightweight equivalent) so updates stay in sync. The reminder must appear as a popup message even if the device is locked, but should never override the user’s system settings for Do Not Disturb. Verses can live in a small local bundle for offl...
iOS ve Android’de çalışacak bir mobil uygulama geliştiriyorum ve arka uç olarak Supabase kullanacağım. İlk hedefim, kullanıcıların uygulama içinden ses dosyası yükleyebilmesi.

Widyo Onarcam adını verdiğim yeni mobil uygulama için deneyimli bir geliştirici arıyorum. Uygulamanın temel amacı, kullanıcılara belirli konularda hızlı ve düzenli bilgi sağlamaktır. Beklentilerim: • iOS ve Android’e aynı anda çıkabilecek, sorunsuz çalışan bir sürüm • Temiz, ölçeklenebilir kod yapısı (React Native, Flutter veya benzeri çapraz platform tercih edilir) • Basit ama şık bir arayüz: ana bilgi akışı, arama/filtreleme ve favorilere ekleme bölümleri • Push bildirimleri ve temel analitik entegrasyonu Proje sürecinde: – Taslak akış diyagramları ve wireframe’leri birlikte netleştireceğiz. – Haftalık ilerleme demosu almayı, Git üzerinden düz...
