No funciona!

Pagué para poder poner sets y ni así funciona, que decepción, ya no la actualizó el creador.

Useless, muscle rest timers don’t work

Have tried to create muscle rest timers and save them, but they don’t appear in the list of saved timers. When I try to launch one from the main view, it never starts.

Terrible bugs. This app looks like it’s no longer maintained. Avoid.

Requiere suscripción para apple watch

Necesitas pagar mensualmente para usar la app en el Apple Watch. ¿En serio?

Response from developer

Hi there, thank you for your feedback. We totally understand your concern, and rest assured that we have no intention whatsoever to steal our user's data. It seems that the "copy clipboard" bug occurs due to iOS 14 security settings and it has been fixed in the latest version, please do update your app. Feel free to write to us at support+fstimer@alphapod.com if the issue persists so that we can look into it immediately.
