{"appstoreID":6769581713,"title":"PRMaxxing","subtitle":"Built for serious lifters","developerName":"Brian Bounds","description":"I built this app because I wasn’t finding a logger that treated lifting like lifting. Most apps pushed gamification, AI coaching, and social features that got in the way. So I built the app I actually wanted in the gym. That means a completely free app for experienced and serious lifters. No social features, no gamification, no internet required for logging, and no AI. I didn’t want another app trying to motivate me or tell me how to lift. I wanted to build my routines the way I wanted, log sets easily with the features I wanted, and look back at honest training history. PRMaxxing is that.\n\nWhat you get with my app\n* Fast set logging built for the gym\n* Full routine control: set types, rest timers, supersets, unilateral logging and more\n* Honest history you can edit, with real PR tracking\n* Automatic progression schemes\n* Many graph types and tracking tools that show real progress\n* Warmup presets you can tune your way\n* Completely free, with no accounts, and no data tracking. \n\nQuestions or feedback: prmaxxing@gmail.com","bundleID":"com.ironlab.iron-gym","appiconURL":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/60/42/58/604258c0-5049-a063-a606-f7f67d773b18/Placeholder.mill/1024x1024w.webp","formattedPrice":"Free","appUpdated":"2026-09-02T20:19:29.000Z","appReleased":"2026-08-28T07:00:00.000Z","version":"1.1","platforms":["iphone"],"minOS":{"iphone":"Requires iOS 17.0 or later.","mac":"Requires macOS 14.0 or later and a Mac with Apple M1 chip or later.","vision":"Requires visionOS 1.0 or later."},"topIAPs":[],"languages":["EN"],"size":"15.3 MB","category":"Health & Fitness","developerWebsite":"","screenshots":[{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/e7/0b/3d/e70b3deb-58f2-e83b-5ac4-63b940d7f0c4/01.png/1206x2622w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/0c/93/04/0c930461-ddda-52d1-2ce1-8f5927573085/02.png/1206x2622w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/b6/0c/ef/b60cef01-ffff-880f-3979-b0f7143eb5f3/03.png/1206x2622w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/81/04/18/8104186c-62b7-079e-7174-17676c7a5136/04.png/1206x2622w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/16/35/92/163592cd-7661-5938-534b-5a7d169011cf/05.png/1206x2622w.webp"}]}
