Need to be able to change date of entry. I have some past lifts that I want to enter but can only enter as current date and don’t see where date of lift can be changed.

I love how simple this app is. I have been using it for ages, after having tried allot of other apps. I train hybrid, doing CrossFit and weight training and cardio and I use this all the time to track my exercice weights and reps. I have 2 suggestions to improve the app : - 1 : include a search engine in the exercice tab because I have so many exercices logged that it’s hard to find quickly - 2 : enable renaming an exercise for example I misspelled one exercise and I can’t correct it without losing what I tracked Thanks allot !

Clean, simple interface. No data collected. Minimal unobtrusive ads. There’s nothing not to like here.

I would give it 5 stars if it had a graph to show progress of the lifts. Also needs to be able to edit unlimited customized lifts.

Exactly what I was looking for. Calculates 1rpm and saves history of lifts.
