Service
Mobile app development.
iOS and Android from a single codebase
Mobile apps with a native feel for iPhone and Android — from a single codebase, which means faster development and lower costs. From idea to publishing on the App Store and Google Play.
Pricing: custom quote
The price depends on the feature scope. After a free consultation you receive a fixed quote with a clear timeline.

Questions
Frequently asked questions
How much does a mobile app cost?
It depends on scope — a simple app with a few screens costs far less than a complex platform with payments and offline mode. After the consultation you receive a fixed quote.
How long does development take?
Simpler apps are done in 6–8 weeks, more complex ones in 3–5 months. App Store and Google Play review adds a few days up to two weeks.
Does one codebase really work on iOS and Android?
Yes — React Native is used by Instagram, Discord and Shopify. To users the app is indistinguishable from native, while development is faster and cheaper.
Who publishes the app to the stores?
I do — I prepare everything needed (descriptions, screenshots, icons) and guide the app through the Apple and Google review process to launch.
What about updates after launch?
Minor updates can ship instantly with Expo, without waiting for review. For bigger upgrades we agree on a maintenance package or per-scope billing.
