Do you remember how hard Math is? And how it's even harder to do it when you're tired? Like when you're in the Gym, sweating profusely after your last sets, and still need to figure out how many plates you need to use so you can Bench 172 lbs next? If you're just like me (who got dizzy just by reading this example) then you need GymMath! (which is FREE by the way) Because with GymMath' Plate Calculator you can just input the weight you want to lift and it will automatically calculate it for you! You can switch back and forth between kg and lbs, you can change your bar weight, and you can even change or add any plates you want! And have I told you that it's FREE?! If you're not impressed and download it already (shame on you!) then I need to tell you that GymMath can also calculate your 1 Rep Max accurately! You can choose any of 4 "science backed" formula to get your 1RM (and other rep percentages). And YEAH, IT'S *F.R.E.E*!!! Now while you're happily waiting for the download to finish, I just want to give this little supposedly-written-in-tiny-font disclaimer info that I actually show ads in GymMath. **Heey, your brother needs to buy his Protein Shake** Lastly, in the off chance that you're still reading, hopefully already downloaded GymMath, here is the TLDR; version: Features: - Plates Calculator: Calculate weight plate you need - Customise your bar and plates - Rep Max Calculator: Estimate your 1 rep max and other weight percentages - Save your workouts and see the data in chart - Choose between 4 One RM formula - It's Free - Serve ads inside app ## Key features - Plates Calculator - Customizable bar and plates - 1 Rep Max Calculator - Save workouts and view charts - Choose from 4 1RM formulas ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/gymmath-plates-and-1rm-calc/id1460137994/reviews.md ### 3/5 — Good app, could be better *2023-10-19, version 2.1* shows me mostly what I’m looking for. I just wish it would provide more % of 1RM. Currently only goes down to 70% and I need lower than this for my warm up sets. Is this something that could be added? ### 5/5 — Almost Perfect 🤣 *2023-04-05* The only issue is the “Rate GymMath” section won’t bring you to the App Store. Lol. It literally does everything you would want it to! I can feel if I am having a bad few months. When my 1RM hours down, I can tell when I am not eating well or getting enough rest. Best fitness app by far. ### 5/5 — FREE?! *2023-02-27* Blown away this is so simple, comprehensive, and free - all without ads. Thank you for such a great tool! ### 2/5 — 810lbs, 1 Rep Max! *2022-08-02* Apparently if you can bench a 45lbs Olympic bar 35 times, your 1 Rep Max is 810 lbs! According to this calculator! Pretty impressive, but won’t be trying it any time soon! ### 5/5 — The app that’s getting me to 3/4/5 plates. *2022-06-16, version 2.1* Best app for fitness ### 5/5 — Awesome app , does what you need easy *2021-11-11* This is a great free app that helps you keep track of you maxes, gives you % or 1RM, and estimates maxes with reps. It also has a cool feature of calculating what plates to put for a certain weight in case you are not good at Gym Math. Clever and accurate name for the app. Overall great job. Maybe it’s me that I don’t know how to set the timer for tempo or it’s a feature not working right, but there are plenty of apps that are great timers so not too important. ### 1/5 — Crashing... *2020-11-23, version 2.1* Not functional. First minute of using it since downloading and it crashes twice ### 5/5 — Great app *2020-10-12* Should be more hyped up than it is. Great app. ### 5/5 — Romano *2020-08-07, version 2.1* Great app, has everything you need & is so easy to use with no fuss. Highly recommend ### 5/5 — Wish I could get rid of ads *2020-08-06* I like the app. It does what I was looking for. I like that I can use all features without paying money. However, now that I have tried it out, I wish that I could pay a flat $1-$5 to get rid of ads. I found a similar app that will even let me try the feature I want until I agree to $1 monthly, but I do not want to pay monthly. So, I guess I will deal with the ads in this one. ## Frequently asked questions about GymMath ### What is GymMath?
