Tap any zone to see a plain-language explanation and weekly training time recommendation. • Each workout in today's summary now shows a zone badge (e.g. Z3 138 bpm) so you can see at a glance whether your ride or run was a warm-up or a solid aerobic effort. • The workout history page for each activity now includes a zone distribution chart below the existing graphs — showing how your intensity was spread across zones for the selected period, with a plain-language verdict on whether the intensity was sufficient. • The Fitness Progression heart rate comparison now shows which zone each half landed in. If your zone shifted between periods (e.g. Z3 → Z2 at the same effort), it tells you what that means for your aerobic fitness. • Fixed an issue where the zone badge sometimes didn't appear on today's workout card. ## More apps by YAOTSAN TSAI - [Famly - Family Reminders](https://appshunter.io/ios/app/famly-family-reminders/id6776103025) - [TwoRetire](https://appshunter.io/ios/app/tworetire/id6792512974) All apps by YAOTSAN TSAI: https://appshunter.io/developer/1895623409 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
