# iOS

Yggdrasil is supported on iOS thanks to a native app currently in TestFlight. It
can be used on both iPhones or iPads and is implemented as a VPN extension.
Although it should work on most recent releases of iOS, using the latest version
is recommended.

## Notes

- Functionality in the app is somewhat limited compared to Yggdrasil on other
  platforms - some features like crypto-key routing are not available at this
  time
- The app is developmental and might have some bugs or may, in some limited
  cases, drain battery power. Please make sure to report bugs to us via
  Matrix/IRC
- Each TestFlight release is only valid for 90 days. You will be notified by
  push notification and/or email when a new TestFlight build is available so
  please make sure to upgrade as soon as possible after each release
