Works with your existing gym — just your phone. Nothing to install, nothing to buy.
Adds the one layer every tracker is missing — proof it is working.
Home setup, hotel gym, on the road. Your progress follows you anywhere.
Weeks 6 through 12, real progress goes invisible — no proof it's working, so it stops feeling worth the time and money. That's when people quit. Not at the start.
Dropout peaks in weeks 6 to 12 — the exact window where progress goes invisible and doubt sets in.
Heart rate and calories carry up to 40 percent error during lifting. It looks like data. It isn't proof.
Two thirds of memberships sit idle. Not because people lack motivation — because nothing ever showed them it was working.
Progress feels invisible — not because you are not working, but because wearables were built for cardio, not lifting.
Heart rate, calories, and RPE estimate effort. None of them can tell you whether your muscles actually produced more force this week than last.
ITERUM gives you one objective number: what you lifted, and how fast you moved it.
So the only question left is simple — did you get stronger this week?
What your wearable sees during a set — not the force you produced.
Every rep is an iteration. Every session is a return. The goal is not to do more than last time — it is to come back, and be better than last time.
We are fixing that.
The ITERUM beta is live. We are opening access to 50 members to help shape the product. Sign up in the app to get started.
No credit card. No commitment.
