Hello

Want to suggest you to implement 1RM calculation feature https://en.wikipedia.org/wiki/One-repetition_maximum

I see it like this:

There is a dropdown list in "Setting" with one of two Epley or Brzycki formulas or some others.

I see a calculated 1RM on "Home" screen like this

Also may be on "Edit set" screen too

Calculation should be on the fly. When the formula is switched, the results on Home screen are also recalculated.

There is currently a one-rep max calculator in the best view page.

Also I just went with Brzycki formula, because after testing all the different formulas, I saw the progress graphs generally looked the same. This way we can just focus on the progression rather than worrying about what our theoretical one-rep max might be. I think I saw some paper on pubmed finding Brzycki to be the most accurate, but my P.T. contradicted this. In the end all we need is a rough idea of what our progress looks like so it doesn't matter.

Oh sorry, missed that

Looks good and fits to me.

One more small suggestion) is add rounding. 14 digits after point is meaningless.

About formulas, they say that some of them more fit for the upper body exercises (bench press) and some for lower body (squats and deadlift). But agree for the progress it does not matter.
