Mobile App Development Company for Startups

Who this is for

Problems we solve

Cross-platform mobile app development

Most startups do not need two separate native apps. We build with React Native and Expo, so one codebase ships to both iOS and Android, with native components and access to device features like the camera, location, push notifications, and payments. That keeps the first release faster and cheaper, and future features land on both platforms at once.

If you are deciding between frameworks, our React Native vs Flutter guide explains how we choose.

Backend, data, and integrations

A mobile app is only as reliable as the backend behind it. We set up authentication, the database, file storage, and push notifications — usually on Supabase or Firebase — and connect payment providers, maps, messaging, and your existing systems through APIs.

Our Supabase vs Firebase comparison explains how we pick the backend for each product.

From idea to the App Store and Google Play

We work in short, reviewable cycles: you see real builds on your own phone early, not just designs. Before release we test on real devices, prepare store listings and screenshots, handle privacy and permission requirements, and manage submission and review feedback for both stores.

After launch we monitor crashes and early feedback, fix what blocks users, and plan the next set of features with you.

Mobile app development cost

A simple mobile MVP typically costs $4k–$8k, a standard app on both iOS and Android $8k–$18k, and apps with multiple user roles, real-time features, maps, or AI $18k–$40k or more. See our guide on how much it costs to build an app, or get a range for your own features with the app cost calculator.

FAQ

Do you build native or cross-platform apps?

We build cross-platform apps with React Native and Expo, which use native components and can include custom native code where a feature needs it. For most startups this is faster and more cost-effective than two separate native apps.

How long does it take to build a mobile app?

A simple MVP usually takes 4–6 weeks, a standard app 8–12 weeks, and an advanced app with multiple roles or real-time features 12–18 weeks.

Do you build native Swift/Kotlin apps?

Most projects use React Native / Expo for shared iOS and Android delivery. Fully native work is discussed when device APIs or team constraints require it.

Do you guarantee App Store approval?

No. We prepare compliance checks, assets, and submission support. Store decisions remain with Apple and Google.

Is this different from your React Native service?

This page is about the product decision — whether to build a mobile app and what belongs in v1. If you already know you want React Native specifically, our React Native development page covers the engineering side in more depth.
