Build · Mobile App Development
Mobile app development for iOS and Android
Apps your customers open every day — designed for ordering, booking, loyalty or field operations.
What mobile apps does Netsta build?
Ordering and loyalty apps, booking systems, operations apps for field teams and the mobile side of SaaS products — apps people come back to.
We test user flows with a clickable prototype first, then build. Most projects use Flutter or React Native; for platform-specific needs such as camera, Bluetooth or heavy animation we build natively in Swift (iOS) and Kotlin (Android).
We also handle store submissions, privacy declarations and release updates.

Native, cross-platform or PWA?
Short version: cross-platform for most business apps, native when you need deep device access, a PWA when you don’t need the stores.
| Criteria | Native (Swift/Kotlin) | Cross-platform (Flutter / React Native) | PWA |
|---|---|---|---|
| Best for | Heavy hardware use, games, AR | Most business and consumer apps | Simple tools that don’t need a store |
| Codebase | One per platform | One codebase, two platforms | One web codebase |
| Performance | Highest | Very good | Good |
| Store listing | Yes | Yes | No (installed from the browser) |
| Maintenance load | High | Medium | Low |
Standard in every project
Never sold as an add-on — part of every delivery.
Security
OWASP checks, role-based access and data storage that complies with KVKK and GDPR.
Performance
Fast screens, with Core Web Vitals measured before launch.
Clean, tested code
Code review, automated tests and CI/CD for safe releases.
Docs & handover
You own the code and the docs, and your team gets a handover session.

Frequently asked questions
How long until a mobile app is live?
A focused first version usually reaches the stores in 10–14 weeks, including store review. Your quote includes a dated plan.
Do you need to build separate apps for iOS and Android?
Usually not. We build both platforms from one Flutter or React Native codebase and tell you up front when a feature needs native Swift or Kotlin code.
Do you handle the store submissions?
Yes. We set up developer accounts and manage store assets, privacy declarations and the review process.
Do you keep the app updated after launch?
Yes. A maintenance plan covers OS updates, bug fixes and new features.
Have an app idea?
Let’s prototype it first, test it with users, then build.
