Great for calculating reps

Great for calculating one rep max and predicting number of reps at different weights. It also saves your maxes. It would be nice if the saved maxes would show max weight for different amounts of reps.

Numbers won’t work

Can’t type 3-9 numbers in “reps”, buttons just won’t work. Tried to delete and re install the app, no result.

Also it would be nice to have the option to count uneven numbers like something.5kg

Good but could be better

Wish I could have my percentages at all times. But I like the app overall.

Single digit reps?

I can only enter single digit reps, this app is garbage. What if I did 10 reps? Oh nooo I broke the app.

Enjoy my $2; the only thing worse than theft is discovering the thief was grossly incompetent.

FAQ

What is a 1RM and how does this app calculate it?

Your 1RM (one-rep max) is the maximum weight you can lift for a single repetition on a given exercise. This app uses a scientifically devised formula to accurately estimate your 1RM without requiring you to perform a maximal lift, which can be risky. You input your weight lifted and repetitions, and the app calculates your estimated 1RM.

What lifts can I track with this app?

The app supports a variety of common lifts such as the deadlift, bench press, and squat. You also have the flexibility to add your own custom lifts if they are not pre-listed. This ensures you can track your progress on all the exercises that are important to your training regimen.

How does the app help me track my progress?

You can track and chart your 1RM history for each specific lift you record. This visual representation allows you to see how your strength is developing over time. Additionally, you can add notes to each 1RM calculation, providing context for your performance on that day.

Is this app free to use?

Yes, this application is completely free to use. It does not feature in-app purchases or advertisements, providing a clean and uninterrupted experience for users focused on their strength training calculations and tracking.

What are the benefits of knowing my 1RM?

Knowing your 1RM is crucial for many training programs, as they often prescribe workouts based on percentages of your maximum lift. It helps you gauge your current strength levels, set realistic training goals, and ensure you are lifting appropriately to stimulate muscle growth and strength gains safely.
