Great ideas, needs some polishing.

I love that I can actually build my own programs and set different methods to drive progression.

Some of the ui and quality of life features could use some work

FAQ

What is a 1RM Calculator?

A 1RM Calculator is a utility that estimates the maximum weight you can lift for a single repetition. You input the weight you successfully lifted and the number of repetitions you performed, and the app calculates your estimated one-rep max.

How does this app help with strength training?

It helps you gauge your current strength levels and track your progress over time. By comparing different lifts and rep schemes, you can better understand your strength gains and plan future training sessions more effectively.

What features are available in the Pro version?

The Pro version offers an ad-free experience, the ability to save and track your lift history, historical chart and list views categorized by exercise, more estimation formulas, calculation of multiple rep maxes, unit switching (lbs/kgs), and a percentage view of your 1-rep max.

Is this app compatible with both pounds and kilograms?

Yes, the Pro version of the app allows you to switch between pounds (lbs) and kilograms (kgs) for your weight entries and calculations, making it suitable for users worldwide.

How accurate are the 1RM estimates?

The app provides estimates based on the data you enter. These calculated values may vary from actual measured values. It's important to always use a spotter and warm up adequately when attempting to find your true maximum lift to prevent injuries.
