Custom mobile app development for your business
Real, production apps with a solid back-end and AI inside — not template apps that break after launch.
LetinAI builds custom mobile apps for businesses across India. Android, iOS and cross-platform apps for management, operations and customers — built with Flutter and React Native and connected to real systems and AI.
Apps that do real work, not just look good
A business app is only useful if it does real work — logging field activity, taking orders, tracking operations, or putting your service in a customer's pocket. Too many apps are pretty front-ends with no solid back-end, so they are slow, insecure, or break the moment real data flows through them.
LetinAI builds custom mobile apps the right way: a clean app on top of a robust back-end, secure data, and a workflow that matches how your business runs. We build for Android, iOS and cross-platform, and connect the app to your existing systems and AI.
How we build your app
We use Flutter and React Native to build once and ship to both Android and iOS quickly, with native Android where it is needed. Behind the app we build the back-end, APIs and cloud, and we can connect it to your ERP, CRM, inventory or billing so the app and your business stay in sync.
We can also add AI inside the app — chat assistants, recommendations, or computer vision. We have built deployed apps including a clinic patient-management application that cut admin work by roughly half, so you get a partner who ships real, working software.

How much does custom mobile app development cost in India?
It depends on scope — a focused single-purpose app costs far less than a full app with back-end, payments and AI. LetinAI scopes each project to your needs and offers a free 30-minute consultation before any commitment.
Do you build for both Android and iOS?
Yes. We use Flutter and React Native to build cross-platform apps that run on both Android and iOS from one codebase, with native Android development where it is needed.
Can the app connect to our existing software and AI?
Yes. We build the back-end and APIs to connect your app to your ERP, CRM, inventory or billing, and can add AI features like chat assistants, recommendations or computer vision.
Will you support the app after launch?
Yes. As an Ahmedabad-based team we provide ongoing support and updates after launch, and the app stays yours to extend as your business grows.
