Zentro

Zentro is a modular "super app" built with Expo and TypeScript — a single shell that hosts 15 independent modules: AI assistant, chat, tasks, calendar, deals, wallet, activity tracking and a tools section.What makes this different from most templates: the external service connectors are real. OAuth flows for Notion, Gmail, Google Calendar, Google Drive, Google Fit and Evernote are implemented against the actual APIs, with token storage and refresh handling on an Express backend.
WHAT YOU GET

The OAuth layer alone is typically a week of work.WHAT IS NOT INCLUDED- No in-app purchases — you add your own billing layer- UI text is German; strings are centralised and straightforward to translate- You supply your own API credentials for each connector- Not submitted to Google Play — this is source code, not a finished product
