Safety precautions The calculations performed in oneRM are based on validated formulas, still they can be only estimations of the real weight you might be able to handle and should be used as a guidance. Measuring your 1RM can put your body under great stress, so be sure to perform it under safe conditions. Studies revealed that no more than 10 repetitions should be used in linear equations to estimate your 1RM. We included the possibility to calculate your 1RM also for 10 to 20 repetitions, please be aware that any 1RM calculation that result from values over 10 repetitions can only be considered as rough estimation.

Making a new workout routine and wanted an easy way to calculate the weights at required percentages. This app is sleek, fast and, most importantly, EASY! Great app for calculating 1rm and the resulting percentages Highly recommended.
A FREE app and a life saver. You get instant 1RM with various methods to calculate . Repmaxes for RPE based programs and everything on the main screen. App UI looks like a paid app. Strongly recommended.
I compete in powerlifting and programming workouts can be difficult. So I was introduced the this app and was instantly hooked. The results were awesome, I didn't get 400lbs on bench press but the attempt was beautiful. My Deadlifts increased by 15lbs. I will be using and referring this app to everyone.....God Bless
I like the flexibility to add your own excercises and the ease of use, takes only seconds to add a set.
Easy to use handy little app. I love that you can select different 1rm formulas, or even select multiple to get the average between them!!
Love this app. Simple. Does all the calculations for me. Includes Wendler 5-3-1. Does not have any ads!!
Best app in its class!! Simple, great interface and no adds. Double thumbs up 👍 👍
This is more than a simple 1rm calculator. The best part about this app is the built in 5/3/1 calculator, where you can set the desired percentages of you TM. If I had to give just one advice, I'd say to add an 85% of TM option on the 5/3/1 calculator, as per the changes made in 5/3/1 Forever
Exactly what I was looking for. Clean interface and simple to use. Excellent app.
Great clear no nonsense app. Much easier to use than the top rated app store alternatives.
Easy to use. Need to improve, for example you should add other capabilities like 15RM. You can use NASM Guidelines book with permission to calculate or predict RM's.
Not accurate at all. My maxes are more and I know it for a fact. Cool layout I guess?
Freaking love this app. Has a log which saves your 1repmax. Better than the other 1repmax apps. Gives you percentages and weights and different rep calculations of your 1 rep max. And vice versa it will take your rep number and weight used and calculate your 1 rep max from that. Gives you choice of mathmetical algorithns to use in figuring 1repmax as well.
Love this! Very simple, just the stats needed.
Simple interface and easy to use.
No ads, no ad ons, only doing what it needs to
I love this app. Simple design makes it easy to use.
Great quick check on rep days. Takes only seconds.
Does exactly what I expected. Easy to use and understand.
Simple and efficient
Great workout for High School Football Players
easy to use and just what I was looking for
the programmer is a smart dude. His calculator is perfect for percentage-based weightlifting, max 1Rm forward and backward calculations, different formulas can be selected, he shows the formulas, you can store lifts for reference, etc. it's a unique and awesome app.
