// Coming to iOS & Android
The only barbell calculator that knows exactly what plates you have — at every location you train.
What's Inside
Home gym. Commercial gym. Garage. Each location remembers its own plate inventory so you always get accurate combinations — not a generic standard set.
Type the target weight, see plates per side instantly. Visual barbell diagram. Reverse calculator works too — load the bar and find the total.
See your key training percentages at a glance — 50%, 60%, 70%, 80%, 90%, 95% and more, all calculated off your entered weight or saved max lift. Perfect for programming and warm-up sets.
Track PRs on all major lifts. Pre-loaded exercises or custom ones. View history and watch your numbers climb.
Your inventory and lift history follow you across every device — iPhone to Android, home to gym, seamlessly.
Automatic backup via iCloud on iOS and Google Drive on Android. Delete and reinstall — everything comes back.
Dark mode by default. Haptic feedback. Bold, readable numbers. Works 100% offline — no signal, no problem.
No more using a "standard" plate set. Tell PerSide what you actually have at each location — it only shows combinations that exist on your floor.
Switch locations in one tap. Everything recalculates instantly.
