Release Date
This version was released on April 2, 2026.
New Features
- Include deleted exercises in the next workout: When resolving a workout execution, you can now opt in via a new checkbox in the workout UI to include previously deleted exercises.
- Exercise info popup on demand: The execution preview intro popup can be reopened anytime via an info icon in the header instead of only showing once per device.
- Universal Payment Component (UPC): The new UPC-based payment flow is available in the app and includes improved error handling.
- Units in 1RM and plate calculator: Both calculators now respect the configured unit system (metric or imperial).
- Adyen secure fields: The Adyen input fields in the payment flow have received proper styling.
Fixed Bugs
- On Android, the IBAN signature field in the UPC payment flow did not reliably accept swipe input. This has been fixed.
- When the new payment method during an amendment was not SEPA, the UI showed incorrect content. The flow has been simplified and now displays correctly.
- On iOS under a network proxy, only one production app could run at a time. The underlying crash has been fixed.
Technical Changes
- Improved address formats on the Connect page, in registration links, and in Discover mode for Spain, Turkey, Australia, and Ireland.
- Updated FitX consent texts.
