Flutter app development for iOS and Android
We build cross-platform mobile apps in Flutter: one codebase that ships as native iOS and Android apps, with the back end, admin panel and integrations built by the same team.
What we build
What we build with Flutter
Consumer apps
Chat, social and marketplace apps with sign-in, push notifications and in-app messaging.
Companion apps for your platform
Mobile apps for your customers or field teams, built on your existing web platform and APIs.
AI features on mobile
Chat assistants, photo and document capture with AI extraction, and smart search, calling Claude, OpenAI or Gemini through your own back end.
Why Widle
Why we build mobile apps in Flutter
One codebase for iOS and Android means one team, one set of tests and releases that reach both stores together.
- 01
Shipped in Flutter
We built Krushin, an anonymous chat and dating app for iOS and Android, in Flutter with a Laravel and MySQL back end and Firebase.
- 02
Back end included
APIs, database, admin panel and push notifications come from the same team, so nothing gets lost between vendors.
- 03
Built to hand over
Clear state management, tests and documentation, kept in your own repositories.

One secure place for clients, vendors and partners to onboard, share documents, check status and pay, instead of chasing you by email.

Where we use Flutter
Flutter FAQs
Flutter or React Native?
Both build iOS and Android apps from one codebase. We suggest Flutter when the app needs a polished custom interface that looks the same on every device. React Native can make more sense when your team already works in React.
Can you build the back end and admin panel too?
Yes. We build the APIs, database and admin panel alongside the app, on Laravel, Node.js, Go or Supabase, depending on what you already run. Krushin’s back end runs on Laravel and MySQL, with Firebase.
Who owns the code and the app store listings?
You do. The code and IP are yours, we sign an NDA before we start, and we recommend publishing under your own Apple and Google developer accounts so you control the listings.
Can you take over an existing Flutter app?
Yes. We start by reviewing the code, packages and release setup, then agree priorities with your team.
