Your equipment
is already smart.
It just needs a sticker.
We send you QR stickers for your machines. Members scan and log workouts in a free app — you see which machines they actually use. That's it.
How it works
It all starts with a sticker.
Simpler than it looks. Here's how.
Send us your email — we handle the rest
Fill out a short form. We reach out to ask about your gym — how many machines, where to ship. We prepare the stickers and deliver them to your door, ready to assign.
Stick it, scan it, pick the equipment
Stick a sticker on a machine where members can see it. Scan it with our free app — a catalog with photos pops up, just pick the match. Or type the sticker number on the web dashboard. Repeat for every machine — the whole gym takes under an hour. Made a mistake? Reassign any sticker anytime.

FAQ
Common questions.
Yes — they download the free Muscle Diary app once. The first time they scan a QR code, they're taken straight to the App Store. The whole install takes under a minute. After that, every scan opens the app directly with that machine's exercises already loaded and their last weights pre-filled.
Yes. Members can search any exercise manually, log workouts from scratch, and track their full history without ever scanning a sticker. QR codes just make it faster — scan instead of search.
Contact support and we'll add it within 48h. Pilot partners get direct access to our team — no ticket queue, no waiting weeks. If you have a machine we haven't seen before, we want to know about it.
Even 20–30% adoption gives you a meaningful signal on which machines are actually being used. Your dashboard shows the adoption rate so you always know what you're working with — and most gyms see it grow naturally as members notice the stickers.
Standard pricing starts at €0.99 per QR code per month. No auto-contract, no surprise invoice — you decide whether to continue. Your stickers stay on the machines and keep working either way.
Cancel anytime. After the pilot, billing is monthly with no minimum term and no annual lock-in. You're not signing a contract today — you're starting a pilot.
You see anonymised usage per machine — how often each piece of equipment was scanned, when, and usage trends over time. Members own their personal workout history and you cannot see individual logs.
You get a full export of your usage data before anything is deleted. Your equipment assignments and QR sticker IDs are yours — they don't become useless the moment you leave.
The gym your members keep coming back to.
Give them a reason to track every session. No app development. No hardware. One sticker per machine — that's all it takes.
QR workout tracking for gyms
Muscle Diary turns any gym machine into a smart workout station with a single QR sticker. Members scan to log sets, track progress, and access full exercise instructions — no manual entry, no guessing. As adoption grows, you build a real picture of how your floor is used.
Equipment usage analytics
Know which machines run hot and which ones collect dust. Muscle Diary gives fitness studios and gym operators real usage data by machine, by time of day, and week over week — so decisions about layout, maintenance, and new purchases are based on numbers, not gut feel.
Free workout app for gym members
Every member at a Muscle Diary partner gym gets a free workout tracking app. No subscription, no upsell. Scan the machine, log the session, track personal bests — and share full training routines as a QR code. Available on iOS and Android.
