Tasky — calendar app for teams
Events, tasks and reminders in one place — planned together as a team and reliably synchronized, even without an internet connection.
- Android
- Kotlin
- Jetpack Compose
- Offline-first
- REST API
Shared planning — available anywhere
Tasky is a calendar-based app for managing events, tasks and reminders. Users register, maintain their personal agenda and, as hosts, create shared events to which they invite other attendees simply by e-mail address.
The special requirement: the app has to work reliably even when there is no internet connection — on a train, for example. That's why Tasky is built consistently offline-first: all changes are stored locally and automatically synchronized with the server as soon as a connection is available again.
- Personal agenda — events, tasks and reminders in a daily overview
- Shared events — create events as a host and invite attendees by e-mail
- Push notifications — reminders configurable from 30 minutes to 6 hours in advance
- Offline-first — fully usable without internet, automatic background synchronization
- Secure sign-in — industry-standard authentication (JWT)
- Responsive design — phone and tablet, portrait and landscape, light and dark theme
