Overview
Why this matters
Whether it's a workforce tool, a customer portal or an internal productivity app, the bar set by Notion, Linear and Figma is now what your users expect from every screen they touch.
Savvytech builds applications that meet that bar — TypeScript end-to-end, realtime collaboration, offline-first sync, and a design language that makes enterprise software feel premium.
Benefits
What you can expect
One codebase, every platform
Web, iOS, Android and desktop from a single TypeScript codebase reduces cost and accelerates iteration.
Realtime by default
Live cursors, multi-user editing and instant updates — without engineering it from scratch.
Offline-capable
Local-first data sync means your users keep working on the MRT, in lifts and at client sites.
Production polish
Animations, empty states, error handling and accessibility — the details that separate good apps from great ones.

FAQs
Common questions
Don't see your question? Get in touch and we'll get back within one business day.
Native or cross-platform?+
We default to cross-platform for cost and speed, and recommend native modules or fully native apps when performance, hardware or platform UX demands it.
Do you handle App Store submission?+
Yes — including Apple Developer, Google Play, signing, review responses and ongoing release management.
Can existing apps be modernised?+
Often yes. We audit the existing codebase and recommend either incremental refactor or a phased rewrite, depending on the state of the code.
