How we build your app

A clear process with something you can test every week.

Free scoping call

We learn what you're building, who it's for and what a successful launch looks like.

Written scope & fixed quote

Features, screens, timeline and a fixed price, within 24 hours of the call.

UX & UI design

Wireframes, then clickable designs you approve before any code is written.

Weekly builds

Development in short cycles. You test real builds on your phone via TestFlight and Play testing tracks.

QA & store submission

Real-device testing, then we submit to both stores and handle review feedback, free.

Launch & growth

Store listing, tracking and first campaigns on Google, Apple and Meta, with a month of launch marketing included.

Mobile app development cost

Every project is a fixed price for a written scope. Simple apps for international clients start from $699. MVPs and full products are quoted after a free scoping call, because the price depends on features, platforms and integrations. A senior team in India typically costs a fraction of a comparable US agency; our guide to mobile app development cost in the USA vs India shows how the numbers compare, and the Flutter and iOS cost guides go deeper.

Every build includes free Google Play and App Store submission and one month of launch marketing, so your first campaigns run on accounts that are set up properly.

Frequently asked questions

How much does it cost to build an app with Appryze?

Every project is a fixed price for a written scope. Simple apps for international clients start from $699, and MVPs and full products are quoted after a free scoping call because the price depends on features, platforms and integrations. You get the quote within 24 hours.

Do you work with clients in the United States?

Yes. Most of our international work is for founders in the US, UK and UAE. We keep call times that overlap US business hours, share a project board, and send a written update every week.

Who owns the code and the app store accounts?

You do. The code repository, Apple App Store and Google Play developer accounts, and cloud accounts are created under your company from the start, with Appryze added as a collaborator.

Do you build native apps or Flutter?

Both. Flutter is usually the fastest way to launch on iPhone and Android with one codebase. We build native Swift or Kotlin apps when a product needs deep platform features or the client prefers native.

How long does it take to build an app?

A focused MVP typically takes around 8 to 14 weeks from approved scope to store submission, depending on features and integrations. Your fixed quote includes a week-by-week timeline, and you test real builds every week.

What happens after the app launches?

Every build includes free App Store and Google Play submission and one month of launch marketing: store listing, tracking and first campaigns. After that you can continue with a maintenance plan, ongoing marketing, or take everything in-house.
