Ratings and reviews

Very accurate calcs. I especially like the ability to add additional exercises. I had created a spreadsheet to do this, but it's more convenient using the app! (Would be nice to be able to delete exercises [due to spelling errors] and to delete duplicate history entries!!.

This app is very good for crossfit and lifting athletes, it would be nice if it had the option to export the information in pdf and/or excel and add graphics. congratulations. Adicional, we can't edit the information.

Great app for checking 1rm, numbers seem to be pretty accurate calculations as well. History feature is handy for tracking multiple lifts.
