Web and mobile apps
A custom web or mobile application is a product designed around your users - customers, partners or employees - and the devices they use. 2Simple does frontend and backend in one team: from mockups, through a browser app (TypeScript, React), a native iOS and Android app (Swift, Kotlin) or a cross-platform app in Tauri, to the API, launch and further development.
For whom
- You need an app for customers or partners and have no in-house development team.
- An internal tool has to work in the office, in the field and on the shop floor - on different devices.
- You have a product that needs rewriting, speeding up or further development.
What you get
- Mockups and a clickable prototype before the first line of code
- Frontend in TypeScript and React, tailored to phone, tablet and desktop
- Native mobile apps in Swift (iOS) and Kotlin (Android), or cross-platform in Tauri
- Backend and API in Node.js or Rust
- Admin panel, user roles and permissions
- Automated and manual tests before every release
- App Store and Google Play release, monitoring and development after launch
How we do it
-
Workshop and mockups: we define the users, key journeys and MVP scope.
-
Iterations: a progress review every 2-3 weeks, with a demo of what is already visible in the app.
-
Launch and growth: deployment, training, further features based on how people use the app.
- 4
- platforms: web, iOS, Android and desktop
- 2-3 wks
- between progress reviews
- 100%
- of the code handed over on acceptance

Questions and answers
Web app, mobile app or both?
It depends on the users. A web app runs in the browser on any device and reaches people fastest. We choose a phone app when offline access, push notifications or device features are needed. You get a recommendation after the analysis.
Which technologies do you use for mobile apps?
Native Swift on iOS and Kotlin on Android when full access to device features and performance matter. When one codebase has to run on several platforms, desktop included, we use Tauri. Web frontends are TypeScript and React, backends Node.js or Rust.
Will you take over development of an existing app?
Yes. We start with a code and architecture review, show the risks and a plan, then take over development gradually, without stopping the product.
How much does a custom app cost?
It depends on the scope. The simplest tools start from around 5,000 PLN; an app with a backend, roles and integrations is a higher range. You get a budget range after the analysis, and we bill hours actually worked.
