I agree, it's would be nice to be able to switch from an incremental system with a limit of weight and a pre-entered weights system. Depending on the situation, both system are needed in the app.

The AI rely on certain research for the rest time. I'm not sure having more energy is a good reason to wait less... Maybe you could if you lifted too litle... For exemple, i did this while i did lift 5lX8r and the next one was asking 10lX6r ...

For me, it's downloading data, clearly... Manage workouts, exercices and programs, Manage profile & Subscriptions details could be nice. Seeing log data will be an no-turn arround for sure (Kind of come with downloading data...)... I would also like to be able to do my exercice with it, rarely but it's could happen. Specially if i do workout from home.

More technically, it's could be both a video or an PNG animation (See APNG) for being more lightweight...

I'm a bit mixed on this, i think it's a good idea but i'm not sure i would use it, when i tap the phone for confirming the set, it's also when i "Discover" the next weight and rep for the next set...

What the % are showing off ?  There seems to be a need of a lot of cal count there...

I suppose it's will come with monday, tomorow ?

For the moment, it's a very small timer on the upper right of the screen if i remindber correctly.

Language mistakes, i agree.
