- first I wanted to always compare my current workout to the previous one (to know what weight to use, how did I do my warmups etc). This I originally did by flipping pages (on paper) or scrolling up.

To solve this I have the history scrolling on top of the current workouts input field.

- I still want to see my progression.

The app does allow tapping on individual lines which shows the details for the lift performed and expands to history of all workouts of the same exercise.

- I want to see which muscle groups I might be neglecting.

The app calculates all the usual statistics like muscle group workload for the last 7 day period and recommends exercises based on what is needed.

To sum it up, it has all the convenience of a notepad (backing up is a copy paste, anything not parseable is a comment) but most of the features of a full workout app with statistics, periodization and so on.

Eventually I want to add some sharing or coaching features.
