Set-by-set logging, a barbell plate calculator, templates, and full training history. Free, no App Store required, works on any device.
Open Platemate →Platemate is a Progressive Web App (PWA). That means it works like a native app — no download needed — and you can add it to your home screen for instant access.
Your first session takes about two minutes to set up. Here's what to do when you open the app.
Sign up with your email — no payment info, no App Store. Your workouts sync to the cloud so you never lose your history if you switch phones.
Hit the + button on the Today tab. Search for an exercise by name, or browse by muscle group. Can't find yours? Create a custom exercise in seconds.
Choose Barbell (with plate visualizer), Dumbbell, Machine, or Other. The barbell view lets you tap plates on and off to calculate total weight — no math needed.
Enter reps for each individual set — not just a total. This is the key difference from most trackers. Your data stays honest: if set 3 dropped from 8 to 5 reps, that's recorded.
The History tab shows every past session by date. The Stats tab tracks your PRs automatically and shows a training heatmap so you can see consistency at a glance.
