Hit your tempo. Every rep.
A magnetic disc that sticks to any gym machine or bar and lights up as you lower the weight — so you always know when the tempo is right. No app. No subscription.
Four numbers.
3
Seconds down. Green when you hit it.

How it works
Three steps. Then it just sits on the bar and coaches the lowering phase.
01
Stick it on
The disc attaches magnetically to any gym machine or bar. No cables, no setup ritual.
02
Lift
Do 2–4 setup reps, then train as usual. The default target is a 3-second lowering phase.
03
See green or red
Green means you hit the tempo. Red means you rushed the descent. A fade means you were too slow.
Why TempoDisc
The cue lives on the bar, not in an app.
A 24-LED ring turns green when your lowering phase hits the target tempo (3 seconds by default). Red when you rush it. A fade when you go too slow.
The disc is about 6–8 cm, snaps on magnetically, and is ready after 2–4 setup reps. A charge lasts about 5 hours. No app. Built for strength and hypertrophy training.
Built for lifters, not for labs.
TempoDisc is for strength and hypertrophy trainees who care about a controlled eccentric and do not want to buy a €300–450 velocity tracker, or run an app between sets. If you already coach a whole roster with a full measurement stack, this is not that tool. If you want a clear yes-or-no on tempo, it is.
A simpler alternative to expensive trackers
Velocity trackers and encoder systems often cost €300–450 and ask you to live in an app. TempoDisc does one job, on the bar, for €59.
