What is mobile app development?
Mobile app development is the design and build of applications for smartphones and tablets running iOS and Android. Native apps are written in Swift for iOS and Kotlin for Android; cross-platform apps use frameworks such as Flutter or React Native to share one codebase across both. Enterprise mobile apps often need offline working, device management, secure sign-in and integration with back-office systems. TechTiera builds native and cross-platform apps and the APIs and cloud services they depend on.

How TechTiera approaches mobile app development
Native or cross-platform?
| Choose | When |
|---|---|
| Cross-platform (Flutter, React Native) | Most business and customer apps; one team, faster releases, lower cost |
| Native (Swift, Kotlin) | Heavy graphics, advanced camera or sensor use, or the newest platform features on day one |
| Progressive web app | Simple apps where store distribution is not needed |
Building field apps that work offline
- Store work locally so technicians can complete forms, photos and signatures without signal.
- Sync safely with conflict rules agreed with the business when connection returns.
- Protect devices with encryption, remote wipe and mobile device management such as Microsoft Intune.
Typical use cases
- Field service and inspections
- Customer self-service apps
- Delivery and proof of delivery
- Sales rep apps
- Patient and member apps
- Warehouse scanning

Mobile App Development FAQs
Should we build a native or cross-platform app?
Cross-platform frameworks such as Flutter and React Native suit most business and customer apps and reduce cost. Native development suits apps with heavy graphics, advanced hardware use or immediate access to new platform features.
How long does it take to build a mobile app?
A focused app with a back end commonly takes 3 to 6 months. Simple apps can be faster; complex apps with many integrations are delivered in phases.
Can enterprise apps work offline?
Yes. TechTiera builds apps that store work on the device and sync with back-office systems when a connection returns, with agreed conflict rules.
Do you publish apps to the App Store and Google Play?
Yes. TechTiera handles store submission, review requirements and updates, or private distribution through your device management platform.
