5 stars: Open source saves the day yet again. Beautifully simplistic. I've tried many apps of this nature and this one has been the best so far. I just started starting strength, and each time I go I have this app open so I can log what I'm doing as I'm doing it, and then compare it to what I did last time. For each exercise you can also keep notes about what you ate that day, changes you made to form, how much sleep you're on, etc.. Being able to visualize progression on each lift is also a nice feature.
5 stars: This is the only app that I have kept on Android every since I acquired it long ago and the only fitness app I always recommend to anyone I know who has an Android. The continuous updates to make it intuitive and useful is simply the best. Every time I think this app should add on something the next update is already including it. If there's one suggestion I would like to make which would help tremendously (at least for me) are to add a feature that helps with workout programs like 5/3/1 into the sets so I don't have to think about the percentages or to adjust my weights for my next sets. It will just do it automatically for those next sets in the next workout. That would be awesome. Thanks for creating the perfect fitness app.
4 stars: Love this app for keeping track of what I achieve in a workout session. Also I like that it has long lists of exercises divided into muscle group areas. My one complaint is that the lists don't contain a lot of the exercises...
