Before any mobile app development starts, let's talk about your mobile app or MVP: a free 30-60 minute consultation, no obligation, no pitch. 📅 FREE MOBILE APP DEVELOPMENT CONSULTATION 🔹 Your mobile app or MVP goal, users and constraints on iOS and Android 🔹 Your Flutter, .NET MAUI, BLE, Bluetooth or IoT problem and how I'd solve it 🔹 Flutter vs .NET MAUI vs native iOS & Android: what fits, what I'd avoid 🔹 A realistic MVP scope, timeline and cost range 🔹 What to build first in your mobile app or MVP, and what can wait You leave with a mobile app development plan, whether or not you hire me. 🎯 WHERE MOBILE APP DEVELOPMENT USUALLY STARTS 💡 You have an MVP idea, not a spec A short discovery, then scope, architecture and an MVP roadmap for iOS and Android. A Flutter or .NET MAUI MVP validates your idea on iOS and Android before you spend months on features nobody asked for. 🔧 Your mobile app became a problem Inherited Flutter, Xamarin or .NET MAUI mobile app, original developer gone, bugs returning, iOS and Android releases slipping. I diagnose architecture, BLE, Bluetooth and IoT integrations, stabilize first and extend second, with a written list of risks before touching anything. 📡 You have IoT hardware, and the mobile app is the hard part A BLE device that drops its Bluetooth connection when your iOS or Android mobile app goes to background. GPS tracking killed by battery saving. Offline data from connected devices that won't sync. A store rejection over background location and Bluetooth permissions. I've shipped Flutter and .NET MAUI mobile apps for parking and access systems, BLE and Bluetooth IoT device control, and field inspection of connected devices outside Wi-Fi range. 🔄 You have a legacy app to modernize Xamarin, WPF or aging .NET code. Phased migration to .NET MAUI, or a Flutter rebuild, keeping the business logic, BLE and Bluetooth layers, and APIs that work. I've delivered both .NET MAUI and Flutter migrations, so I know which one your iOS and Android app needs. 🤝 You need long-term mobile app development Ongoing Flutter and .NET MAUI development from MVP to scale, iOS and Android OS updates, store releases, BLE and Bluetooth compatibility, and reliability work that keeps your mobile app and IoT connected devices alive. 🔵 BLE, BLUETOOTH & IOT MOBILE APP DEVELOPMENT Most connected devices projects fail in the mobile app, not the hardware. I build Flutter and .NET MAUI mobile apps for IoT and Connected Devices: BLE scanning, Bluetooth pairing, stable BLE connections in background on iOS and Android, IoT data sync and Bluetooth device setup flows. From a BLE MVP that proves your IoT concept to a production mobile app for thousands of connected devices. 📲 FLUTTER OR .NET MAUI? Flutter: fast MVP development, one codebase for iOS and Android, great UI. .NET MAUI: best when your team, backend or legacy Xamarin code is .NET. I build mobile apps in both Flutter and .NET MAUI, so the advice is honest. ⚙️ WHAT GETS DELIVERED Mobile app development is the core, but an MVP needs more than a mobile app. I cover backend, APIs, IoT integrations and release pipeline, and bring in design, QA and DevOps from my team: one contact instead of four specialists. 📱 Mobile app - Flutter, Dart, .NET MAUI, MAUI, Xamarin, Swift, Kotlin, native iOS & Android 📡 BLE & IoT - Bluetooth Low Energy (BLE), Bluetooth pairing and control, IoT mobile apps, Connected Devices, background BLE connectivity 🗄 Backend - .NET, C#, Node.js, Firebase, PostgreSQL, AWS, REST APIs 🔌 Integrations - NFC, GPS, maps, offline sync, payments, auth, analytics, push, AI & LLM APIs 🚀 Release - CI/CD, App Store (iOS), Google Play (Android), Bluetooth and location declarations 🎨 Design & QA - UI/UX, Figma, MVP prototypes, testing on real iOS & Android devices 🌍 INDUSTRIES IoT & Connected Devices · Healthcare · Parking & access control · Fleet & logistics · Fintech · Ecommerce · CRM & enterprise · Education · Fitness · Agritech · Real Estate · Field inspection · Veterinary · Travel · Marketplaces Mobile app development · Mobile app · MVP · Flutter · .NET MAUI · MAUI · iOS · Android · BLE · Bluetooth · IoT · Connected Devices ✅ TWO WAYS TO START YOUR PROJECT 📅 Book the free mobile app consultation 30-60 minutes on your mobile app or MVP, options for Flutter, .NET MAUI or native iOS/Android, and a plan, whether or not we work together. 📩 Already have a mobile app with problems? Send the repository or App Store / Google Play link. Within 48 hours you get a written assessment of your Flutter, .NET MAUI, iOS or Android app: top risks, what blocks your next release, and whether I'd fix, rebuild or freeze. No obligation.
