It's coaching, not a diagnosis. If you've had a recent serious injury or surgery, or you have any of the serious signs on our safety page, get it checked by someone who can examine it first.

Tell the app. After each session you can say which exercise hurt, how much from 0 to 10, and what it felt like. Any pain stops that exercise getting harder. The more it hurts, the more the exercise is eased off. A 9 or 10 takes it to its easiest version, and the app tells you to get help.

If pain is high when you start, exercises are pain-limited: you go until the pain starts, and that becomes your line.

You can stop a session at any time. If pain is sharp, getting worse or worrying you, stop and see the safety page.

The most you'll need is a resistance band. ArcForm is built for home: your bodyweight, a band, and everyday things like a chair, a wall, a towel or a step.

Arc is the coach in the app. Arc is an AI, not a person. Arc runs the setup follow-ups, explains your plan, answers questions and writes your reports. Arc runs on Claude AI models made by Anthropic.

Arc can be wrong. Arc doesn't decide how your plan changes; fixed rules do. Arc explains the change and can pick how it's made within those rules.

There's a daily limit on messages to Arc. When you reach it, you can chat again the next day.

We haven't published an accuracy figure yet, and we won't until we've tested it properly.

The camera sees you from one angle, so some movements are easier to measure than others. It does best when it can clearly see the joints it's measuring. When it can't see you, it pauses counting and tells you. Some exercises aren't measured by the camera at all, and the app tells you when that's the case.

• For standing exercises, stand the phone upright. For floor exercises, turn it on its side and put it on the floor.
• Get your whole body in the frame, head to feet. The app shows an outline to stand in and tells you to step back or come closer.
• Some exercises need you side on to the camera. The app tells you which way to face.
• Fitted clothes help. Baggy clothes can hide your knees, hips or shoulders.
• A well-lit room with a plain background helps too.

Each set starts with a thumbs up to the camera. If you allow the microphone, you can say "go" instead.

No. The camera picture is read on your phone, used to find your joints, and thrown away. No video or photos are saved or uploaded.

What's kept is numbers: reps, holds, angles and the positions of your joints. The privacy policy explains where they're stored.

No. It's optional. With it, you can talk to Arc instead of typing, and say "go" to start a set or "here" and "now" in a movement check. Without it, you tap instead.
