    Cont confirmat

    I already have the full source code for a driver-facing mobile app. What I need now is a quick end-to-end polish: • Comprehensive testing on both iOS and Android—covering core functionality as well as performance under typical driver workloads (real-time GPS updates, push notifications, background operation, low-signal areas). A concise report of any defects and the fixes you apply must be included. • Creation of release-ready builds: one signed APK and one signed IPA. I will provide any keystores, certificates, or Apple provisioning profiles you require; if something is missing, guide me through generating it. • Private distribution. For iOS the app must appear in App Store Connect as an unlisted or Business-Manager/private app so only my drivers with a suppl...

    I’m building a dedicated mobile app that helps athletes strengthen their mental game. The core of the product is a 90 question assessment, a individualized 20 week program, a library of structured mental-performance exercises paired with a robust progress-tracking system so users can see how their focus, confidence, and resilience improve over time. I need a manual and AI assisted generation system for the assessments, program and activities. It also needs portals for the trainer, athletes, parent, and coaches. The app has to launch on both iOS and Android from a single codebase, so I’m happy with Flutter, React Native, or another cross-platform stack you’re comfortable with, provided it delivers native-level performance. The interface needs to feel professional—c...

    I need a certified cybersecurity professional to determine whether my personal Android phone has been subjected to unauthorized access and to help me regain full, lawful control of every component that may have been touched. The device is the only confirmed target right now; however, if traces lead to email or social channels I will widen the scope with you. Your investigation must be forensically sound so that any evidence you uncover can stand up to scrutiny should I decide to take legal action. I am expecting a hands-on approach that covers log collection, malware/spyware scanning, vulnerability mapping, and clear recommendations on how to close every gap you find. Where recovery steps are needed—password resets, two-factor reconfiguration, data restoration—I want you ...

    Tengo mi app Lovable casi lista, pero aún quedan varios detalles técnicos antes de publicarla. Busco a alguien que pueda cerrar este sprint y dejarla preparada para producción: 1. Conectar la API de la base de datos de artículos científicos que ya tengo seleccionada, mostrando los resultados dentro de la interfaz actual. 2. Configurar el plan de pago como prueba gratuita con opción de compra: el usuario disfruta X días sin costo y, al vencer, se activa el cobro recurrente que definamos. 3. Restringir ciertas funciones para estudiantes: solo quienes se registren con carnet y datos académicos podrán acceder a esas secciones. 4. Verificación de correo mediante código numérico enviado al email durante el regis...

    Mobile App for Wearable Safety Device (iOS & Android) I am developing a wearable safety device called NeoLifeGuard for hazardous work environments (construction, industrial sites).

    I need an experienced mobile developer to create a real, reactive trading application that runs on Both iOS and Android. After secure User authentication, the flow should let customers add orders to a Shopping cart–style queue, then complete the purchase through an in-app Payment gateway. Although the focus is trading, I still want the cart paradigm so users can review positions before committing. Real-time prices, order history, notifications, and basic account management will finish the first release. Clean, maintainable code and a native-feeling interface are essential. I am open to Swift/Kotlin, React Native, Flutter, or another modern stack—just explain why your choice best suits low-latency trading. Deliverables • Fully functioning iOS and Android builds u...

    All-in-One Islamic ATHKAR Prayer App

    Freelancer should have arabic language & quran knowledge. I would like a modern, cross-platform Islamic prayer app that brings together the core daily tools Muslims rely on and the personalisation options many of us have been asking for. The foundation is straightforward: accurate prayer-time notifications synced to location, an easy-to-use Qibla compass, and the full Qur’an with side-by-side translation. Beyond those essentials, I want the richness found on the Dua & Azkar site to be woven in. That means clearly organised dua categories, scheduled azkar reminders, and a quick “bookmark” tap that lets users save favourite verses or supplications. The key differentiator is personal content: every user should be able to write a dua in their own words, store it alon...

    I’m ready to turn a fresh idea into a fully-functional Android app and I need an experienced mobile software developer to work with me from concept to launch. This project is strictly for Android, so deep familiarity with Android Studio, Kotlin or Java, common libraries, and Google Play deployment is essential. Here’s what I have so far: a clear problem the app will solve, basic wireframe sketches, and a short feature wish-list. What I’m missing—and what I’m hiring you for—is the technical build, iterative testing, and guidance on best practices so the final APK meets current Play Store requirements and runs smoothly on modern Android devices. Deliverables I expect: • Clean, well-commented source code hosted in a shared repo • A signed, rel...

    I already have a fully working Android build created with OpenCode and AI Agent; the APK is signed, tested, and linked to Firebase. What I need now is an expert release engineer who can turn this work into two live store listings—one on Google Play and a brand-new companion on the Apple App Store. Google Play • Take my existing APK (or convert it to the recommended AAB) • Complete console configuration, data-safety form, screenshots, content rating, and rollout to production Apple App Store I am not yet enrolled in the Apple Developer Program, but I will handle the enrolment fees and paperwork myself. From there, I need you to set up every technical piece I’m missing—certificates, provisioning profiles, Xcode workspace, TestFlight builds, and the final...

    I need a detail-oriented tester who can split a 2.5-hour daily window between rigorous mobile testing and proactive client follow-ups for our high-impact financial app. Roughly 1.5 hours will be spent running functional and performance test suites on the latest iOS and Android builds; the remaining hour is for monitoring the dedicated support channel, reproducing any issues users raise, and replying with clear status updates. During every test cycle you will install the current build on real devices (both iPhone and Android), explore critical user journeys such as account creation, funds transfer, and real-time market data refresh, and push the app under load to confirm stability. Use whichever mix of Xcode, Android Studio, Charles Proxy, Firebase Crashlytics, or similar tools you’r...
