Interactive
Users drag to rotate, pinch to zoom and scrub through the rep. The lowering phase plays slower, and the viewer follows the system reduced-motion setting.
A drop-in exercise layer for fitness products
Every rep, rendered live.
Interactive 3D exercise figures for fitness apps. One engine, every movement, iOS · Android · Web.
Primary
Secondary
A clip is one take. A figure is every take.
Most apps ship a looping video for each exercise: one camera angle, one look, one file per movement. Repglyph renders the movement on the device, so the same figure turns, recolours and scrubs inside your interface.
Repglyph One figure, rendered live, from the same data.
Why teams use it
Brandable
Set your accent colour, a dark or light stage and one of three bodies. The muscle highlights, suit seams and stage ring follow your palette.
Validated
Poses are validated against cited professional and clinical standards, with automated checks on every movement, variant and body. How we check
Motion should be accurate, not just beautiful.
- Cited references
- 273
- Automated checks per run
- 2,633
- Movement families verified
- 53/54
These are automated checks of every pose against documented, cited thresholds for joint angles, contacts and range of motion. They are not a clinical assessment, and independent clinician review of the report is still pending.
Make every figure feel native
Pick any movement, then change the body, the stage and the accent. Everything below is the same renderer you ship, running live.

Running in a real workout app
Setwise is our own workout app, and Repglyph started there. Every exercise opens on a live figure with its working muscles and a rep scrubber, in the app's own colours. It reads the same rig file as this page.
- 448 Setwise catalogue exercises mapped to a rig
- Follows the system dark mode and Reduce Motion settings
Setwise on the iOS Simulator
One component on every platform
Each platform has a native renderer that reads the same rig file, with the same lighting, framing and interaction, so a squat looks the same in your iOS, Android and web apps.

});The target is 60 fps. So far it has been measured on the iOS Simulator, the Android emulator and desktop Chrome, where it holds 60 fps while you drag it. We'll publish numbers from real phones once we've measured them.

Early partner programme
We're working with a small group of fitness apps before general release. Partners get help with integration, a say in which movements come next, and catalogue mapping during onboarding.
Before you integrate
Is this medical advice?
No. Repglyph shows exercise technique. Its poses are validated against cited professional and clinical standards, but they don't replace a coach, physiotherapist or doctor, and they aren't fitted to any individual.
What does “validated” mean, exactly?
An automated suite samples every movement, variant and body type and measures joint angles, contacts, balance, grip width and range of motion against our written standard, which cites 273 references. Each check passes, fails or is exempt with a written reason. The current run is 2,633 checks with 0 failures, and 53 of the 54 movement families are verified. Independent clinician review of the report is pending. Read the methodology.
How big is it?
The rig file for the whole library is about 0.5 MB compressed, with every movement, body and prop. On the web you can also load one exercise at a time, about 15 KB each, so a page only fetches what it shows.
Does it work offline?
Yes. The rig file ships with your app and everything renders on the device. No network calls are needed to show a figure.
Can I map it to my own exercise catalogue?
Yes. Figures are looked up by catalogue ID, and Setwise maps 448 of its own IDs that way. Mapping your catalogue, and adding custom movements, is part of early access.
What about accessibility?
Every figure has generated alt text. The viewer works from the keyboard (arrow keys, Space, Home) and respects reduced-motion settings on iOS, Android and the web, which turns off the intro, the auto-orbit, inertia and other decorative motion.
When can I use it, and what will it cost?
The SDK is in early access, and terms are set with each partner. Request access and we'll be in touch.
