App Development Company in Gujranwala, Pakistan
Bracket Mind is an app development company in Gujranwala, Pakistan, building cross-platform iOS and Android apps with React Native and Expo for businesses and founders. Our own AI expense tracker, Zentally, is in development and not yet on either store; it runs 1,332 Jest tests in CI and has row-level security on all 35 tables.
Updated
One codebase for iOS and Android
We build with React Native and Expo so iOS and Android ship from a single codebase. Zentally, our own AI expense tracker, shows the standard we build to: receipt scanning on Google Gemini with automatic fallback to OpenAI, voice entry on the phone's own speech recognition with an optional cloud mode, and every AI call made from server-side edge functions, so no model key ships inside the app.
- React Native and Expo development for iOS and Android
- App Store and Google Play listings, signing and submission
- In-app AI features: receipt and document scanning, speech-to-text and chat
- Backends on Supabase or a custom API, with row-level security
- Subscriptions and in-app purchases with RevenueCat, enforced on the server
How do you build an app that passes App Store and Google Play review?
Store review tends to reject apps over the unglamorous parts, so we build those properly from the start: subscriptions behind a server-enforced paywall, in-app account deletion, and a privacy manifest that matches the store's privacy answers.
In Zentally, the RevenueCat webhook checks its secret in constant time, keeps test purchases off real accounts and double-checks every downgrade with RevenueCat, and the store listing is checked line by line against what the app actually does.
Who builds your app?
You work directly with the engineers writing the code, with no account-manager layer in between: founder Haseeb Attaullah and a team of full-stack engineers in our Gujranwala office. We have delivered projects for clients in 8+ countries, and every app ships into accounts and repositories you own.

Questions buyers ask
How much does mobile app development cost in Pakistan?
It depends on scope: a focused single-workflow app costs far less than one with AI features, payments and a custom backend. React Native keeps the cost down by shipping iOS and Android from one codebase instead of two. Every quote we give is fixed and in writing, after a scoping call.
Do you publish the app to the App Store and Google Play for us?
Yes. We handle store listings, review requirements, signing and submission for both stores, and you keep ownership of the developer accounts and the code. Our own app, Zentally, is in development and not yet on either store, and we are building it to the same review standards we apply to client apps.
Can you add AI features to an existing mobile app?
Yes. We integrate receipt and document scanning, speech-to-text and chat assistants into existing iOS and Android apps. As in Zentally, model calls run on the server rather than on the device, so no AI provider key ships inside the app.
How do I check an app development company in Gujranwala before hiring?
Ask to see apps they built, how they handle subscriptions, account deletion and privacy declarations, and what their CI runs on every change. We show you our own app, Zentally, directly: it runs 1,332 Jest tests and 24 Deno tests in CI and has row-level security on all 35 of its tables. It is in development, so we demo it rather than send a store link.
