Yudemon Accounts, Multi-Device Sync, and Full Data Exports

Since Yudemon’s initial launch, all your data has lived solely on your device. No accounts, no cloud – just you, your sessions, and your phone. That simplicity worked well, but it also meant there was no way to carry your data to a new device or use Yudemon across multiple devices.
That changes with Yudemon’s latest update.
With the new optional account system, you can now:
- Sync across devices – keep your progress, preferences, and stats up to date everywhere.
- Choose what gets synced – detailed toggles let you keep some data local if you prefer.
- Export your raw data – all your breathing sessions, journey progress, and raw heart rate data, ready for your own analysis.
If you love the fully local experience, nothing changes for you – accounts are entirely optional. But if you want the peace of mind and flexibility of the cloud, it’s now just a few taps away.
This update also comes with improvements to data tracking under the hood, laying the groundwork for more in-depth analytics coming soon. And yes – I’m also working on some much bigger updates, including the possibility of Yudemon on new platforms.
If you haven’t already, update to the latest version and give the new account system a try.

Accounts allow for specifying detailed sync preferences, full data export, and more.
