Verdict. Personal Trainer wins on automated progression, offline-first design, and pay-once pricing. Hevy wins on its social feed, web app, and watch support on both platforms.
TL;DR. Hevy is the strongest social workout logger on the market: a polished feed where you follow friends, like sessions, and copy routines. Personal Trainer takes the opposite bet. No feed, no account wall, everything on-device, and the app itself decides what you should lift next based on how the last set felt. Pricing differs too: Hevy Pro is a recurring subscription, Personal Trainer is a $3.49 one-time unlock.

Hevy and Personal Trainer answer different questions. Hevy answers "what did my friends lift today?" extremely well. Its feed is the best in the category, and for lifters who stay consistent because training is social, that feed is worth a subscription on its own.
Personal Trainer answers "what should I lift today?" After every set you tag how it felt: Easy, Just right, Hard, or Failed. The next session opens with a concrete load suggestion rounded to plates that exist in your gym. Hevy shows you last week's numbers and trusts you to do the progression math between sets. Some lifters prefer that control. Most people, six months in, drift to repeating the same weights, which is exactly the plateau automated progression is built to prevent.
The second structural difference is where your data lives. Hevy is account-based: history sits on Hevy's servers, and the free tier caps how many routines you can keep. Personal Trainer is local-first: install, log, done. No account wall, optional encrypted sync, and a one-time $3.49 VIP unlock instead of a recurring charge. Over three years, a typical Pro subscription costs more than ten times that.
Yes, if you want automated progression and pay-once pricing. Personal Trainer suggests the next-session weight from your per-set difficulty ratings and unlocks everything with a single $3.49 purchase. Hevy is the better pick if you want a large social feed and a web app for desktop logging.
Hevy's free tier caps the number of routines you can save and locks advanced statistics behind Hevy Pro, a recurring subscription. Personal Trainer's free tier has unlimited logging, the full exercise library, rest timer, and progressive overload suggestions; the one-time VIP unlock adds plan sharing, custom movements, and extended history filters.
Personal Trainer. After each set you tag a difficulty rating (Easy / Just right / Hard / Failed) and it proposes the next-session load, rounded to real plate increments. Hevy shows your previous session's numbers but leaves the progression decision to you.
Personal Trainer is local-first: every feature works with no signal and data lives on your device. Hevy logs workouts offline once set up, but account creation, sync, and the social feed need a connection.
Pay-once VIP unlock if you want plan sharing and unlimited custom movements. No subscription.
