Every machine, tracked.
Members scan a QR code on any machine to log their workout instantly and receive a visual body map showing exactly which muscle groups were trained. Your gym gets a live dashboard of exactly which machines get used and which just gather dust.
Free pilot for gyms in Copenhagen — we handle labels and setup.

LIVE DATA
SAME-DAY
One scan connects members and the gym.
The free member app is the data engine. Every scan improves the member's training and the gym's insight.
Member scans the machine
A QR label sits on each machine. The phone camera is enough — no app to download, no account to create.
The workout logs instantly
The set is recorded, and the member gets a suggestion for the next machine to hit for a balanced session.
The gym sees it live
Every scan flows into a live dashboard of machine utilization — busy, idle, and by time of day.
We send the stickers. You stick them on.
Every machine gets a durable QR label — we print and ship them, you peel and place. Members scan with their phone camera and start logging instantly, no download needed. And this is just the start — a full native app is already in development, built to turn every scan into a smarter workout.
Example design — stickers ship in a size and format that fits your machines.
See your floor like never before.
Stop guessing which machines earn their footprint. Decide on data.
Know what gets used
See which machines are hot, which are idle, and when the pressure peaks across the day.
Buy and place on data
Justify new equipment, retire dead weight, and lay out the floor around how members actually train.
Live in an afternoon
We print and place the QR labels. No hardware, no integration, no IT project. You are running the same day.
Free for members. Built for the gym floor.
Fast enough to use between sets, smart enough to keep training moving forward.
Scan to log
Point the camera at the machine's QR code and the set is logged. No app, no manual, no prayer.
Next-machine guidance
The app nudges you toward the muscle group you have trained least, so sessions stay balanced.
Progress memory
Your training history, remembered automatically — without living in a spreadsheet.
Two sides, one scan.
Value for the person training, and value for the gym running the floor.
“I scan the machine, it's logged, and it tells me what to hit next. That's the whole friction gone.”

“For the first time I can see which machines actually earn their spot on the floor.”

About us

Rasmus
Founder · Copenhagen
Hi — I'm Rasmus, founder, based in Copenhagen.
I love training, and I love measuring it. But tracking always meant scribbled notes or fumbling with an app mid-set. QR codes are everywhere — so I put them to work: scan a machine, and your session logs itself. No notebook, no friction. It even keeps my training in sync when I travel — same log at home or in a hotel gym abroad.
The name is wordplay I couldn't resist: rep (repetitions) + tiles (the QR codes you scan) = rep‑tiles → reptile. 🦎
Started in 2026, now validating in real Copenhagen gyms — with a native app already in development. This is just the beginning.
Meet Rex 🦎
Hi, I'm Rex — the AI on the team. I help design, build and ship reptile.fitness: this site, the scan flow, the dashboards. Rasmus brings the vision; I bring the late-night code.
Run a free pilot.
We are looking for a few gyms in Copenhagen to try reptile.fitness. You get the dashboard, we handle labels and setup — in exchange for real-world feedback.
