Cystra Support

Check that notifications for Cystra are allowed in the Settings app, and confirm the reminder was saved with the treatment entry inside Cystra.

Sign in with the same Apple Account used for the original purchase, then use the restore option in Cystra’s settings to bring back "Cystra Pro".

iCloud sync for "Cystra Pro" requires an active internet connection and iCloud enabled for Cystra in the Settings app on both devices.

With "Cystra Pro" active, use the export option in Cystra to generate a concise doctor PDF or a CSV file of your journal.

Use the single delete option in Cystra, which removes your journal from the device and from iCloud at the same time.

The latest version is 1.0, released on July 22, 2026. To update, open the App Store, tap your profile picture, pull down to refresh, then tap Update next to Cystra. You can also turn on automatic updates in Settings › App Store.

Subscriptions are managed by Apple. Open Settings, tap your name, then Subscriptions, and choose Cystra to change or cancel your plan. Cancel at least 24 hours before renewal to avoid the next charge; deleting the app does not cancel it. Refund requests go through reportaproblem.apple.com and are decided by Apple.
