React Native app development, one codebase for both stores
As a mobile app development company based in Dhaka, we design and build apps with React Native and Expo, which means one codebase ships to both the Apple App Store and Google Play. For most products that is the right trade: native look and feel, access to the camera, notifications, location and payments, and roughly half the cost of building two separate native apps. When a product genuinely needs fully native Swift or Kotlin, we say so before any money is spent.
An app project covers the whole path from idea to store listing: a product workshop that decides what the first version is (and what it is not), UI/UX design for both platforms from one design system, the build with weekly test builds on your own phone, a backend on Supabase or Firebase where needed, and submission to both stores under your developer accounts so you own everything.
MVP app development for startups and founders
Most founders do not need a big app. They need a focused first version that proves people want it. We scope MVPs tightly: one core job done extremely well, with the table stakes (sign-in, offline behaviour, push notifications, deep links) done properly rather than skipped. A typical focused MVP takes one to two weeks of design and three to six weeks of build.
App design and development starts at $2,000, app design alone from $1,000 with a full developer handoff kit, and the first core screen of your app is designed free within 6 to 12 hours of the brief. Every app also gets a fast web landing page, so you have somewhere to send people before and after launch.
Our process
Define
One screen described in one sentence per feature. If a feature needs two sentences, it's two features, and we say so.
Design
Flows and high-fidelity screens. The free draft here is your app's core screen, designed within 6–12 hours.
Build
Weekly TestFlight/APK builds from week one. You test on your own phone, not in a slide deck.
Polish
Haptics, gestures, launch screens, empty states. This is the feel layer that app reviews end up mentioning.
Ship
Store submissions handled end-to-end, including the rejection roulette, until it's live.

Common questions
Native or cross-platform?
React Native (Expo) by default. One codebase, both stores, native feel for 95% of app categories. We'll tell you honestly if yours is in the other 5%.
Can you build just the design, and my team builds it?
Yes. App design alone starts at $1,000 with a full handoff kit.
Do you handle the app stores?
Yes, submission to both stores is included, under your developer accounts so you keep ownership.
What about backends?
Supabase or Firebase for most products. Custom Node APIs when the product justifies it. Backend scope is quoted separately and transparently.
How long does an MVP take?
Design in 1–2 weeks, build in 3–6 weeks for a focused MVP. The single biggest schedule risk is feature creep, and we manage it contractually.
Do you maintain apps after launch?
Yes. See the Care retainers on the maintenance side. App tiers are quoted per project.
How much does it cost to build an app?
App design and build at Northcave starts at $2,000 for a focused MVP. Backends, payments and complex integrations are quoted transparently on top. You see the core screen designed free before committing.
Can you build an app for both iPhone and Android?
Yes. React Native with Expo gives one codebase that ships to both the App Store and Google Play with native feel, which is how we build by default.
