Fantastic

Fantastic updates! I have been using this app off and on since 2017 and I still can’t believe it’s free.

New update misses the mark - FIXED

Edit: latest update fixed all of this!

Been using the app for years, nice and simple, easy to use, does what it needs to do. The new redesign update has modernised the interface, which isn’t a bad thing on its own, but it has almost ruined the app experience in terms of usability.

The text is now harder to read.
You now cannot navigate in the app if there is an active timer.
You now have to tap a specific small icon to log a set, whereas previously you could tap anywhere on the set item.

New update rocks

New update is awesome. Thanks dev(s)

Love nSuns

Used this app for years even when updates stalled. Overall love how the app does the math for me weight wise. The UI now sucks. I don’t need pretty, I just need clean and simple. It’s a workout app.

Einfach toll!

Eine die beste Training Apps die ich bis jetzt hatte. Hilft mir sehr viel und ist sehr hilfreich 💪🏻
