Service: Market-Ready App

Custom app development for iPhone and Android

A tailored, polished app from one codebase for iPhone and Android, built to grow with you: the server side, automatic updates, round-the-clock checks and everything the stores require. Fixed price per milestone, from $83,300.

A custom app is tailored to your business, with no app builder and no compromises. It runs from one shared codebase on iPhone and Android, with the server side behind it, login, notifications and a clean delivery. Built to grow with you.

Market-Ready App, fixed price

from $83,300, 3 to 4 months

  • iPhone and Android from one codebase
  • The system behind the app grows with your users
  • Automatic updates, round-the-clock checks, usage insights
  • 90 days of free bug-fixing after launch
  • Emergency handbook, account register and exit plan

Entry price, net; the tax treatment is clarified before contract and stated in the offer. After scoping, the price of each milestone is fixed in writing before work starts.

The code sits in your repository from day one; with each paid milestone, the rights to everything delivered up to that point pass to you.

Start with a check, not a spec

A new build can follow an App Check or a takeover that went well. If an app or an AI prototype already exists, find out first what holds up: see take over an existing app or vibe-coded app to production.

Want to start small? Build a First Version (MVP) from $27,800 first. Want me to run it afterwards? See app maintenance and operation, from $1,400 a month.

Common questions

How much does a custom app cost?

The Market-Ready App for iPhone and Android starts from $83,300. That is the entry price; after scoping, the price of each milestone is fixed in writing before work starts. A First Version (MVP) on one platform starts from $27,800.

iPhone and Android from one codebase?

Yes. The app is built from one shared codebase for both platforms: a single product that works the same on iPhone and Android.

How long does a market-ready app take?

Usually 3 to 4 months. The exact date is set in writing before the build starts.

Should a new build start from scratch?

Not if something already exists. If you already have an app or a prototype, an App Check is usually the cheaper first step; it shows what holds up and what a new build would have to replace.
