BeastieA rep counter that watches
you, not your wrist
Most rep counters feel one arm moving and guess the rest. Beastie props up on the floor, looks at your whole body, and banks a rep only when the movement actually finished. The number you finish with is one you can defend — and then send to someone who doubts it.
If it’s not sure, it doesn’t count.

Every exercise has its own rules.
A rep is not a generic event. What finishes a push-up is not what finishes a squat, so each exercise is counted on its own terms rather than by one motion detector wearing three hats.
Chest down, arms locked out
Elbow angle decides the rep and the hip line keeps it honest — sagging turns a push-up into a stretch. The push-up counter →
Depth, or it was a knee bend
Knees have to close past the depth threshold and stand back to tall. Quarter squats are called out, not counted. The squat counter →
Feet apart and hands overhead
Two movements, both required — the arms are the half that quietly shrinks first. The jumping jack counter →
A wrist infers. A camera looks.
A wearable sits on one limb and reasons outward from it, which is why a wave can become a jumping jack and a shallow dip can become a push-up. A camera sees your shoulders, hips, knees and ankles at the same time, so it can ask a much better question than did something move? — it can ask whether the rep finished. That is also why the count is worth arguing over: the same rules run on both phones in a duel, so neither side is trusting the other's honesty.
The trade is that a camera needs to see you. Beastie checks its framing before a set starts and refuses to count until your whole body is in shot, which is the one bit of setup a watch does not ask for — and the reason the number means anything afterwards.
Solo counts. Duels settle.
Most days nobody has challenged you, so Beastie is a plain honest counter: your PR and your streak move, and streaks pause rather than break when life happens. When you want stakes, call someone out — pick a move, set a number, send the link. They don’t need an account to accept, which is the part most rivals appreciate. Curious where you stand first? Take the push-up test.
Before your first set
What is a rep counter app?
An app that counts your repetitions so you don’t have to keep the tally yourself. Most do it from a wrist wearable, inferring reps from one arm’s motion. Beastie does it from the phone camera instead: you prop the phone up, it finds the points of your body, and a rep banks only when the movement actually completed.
Which exercises can Beastie count?
Push-ups, squats and jumping jacks. Three, done properly, rather than a long list done loosely — each one has its own rules for what finishes a rep. More are added only when they clear the same bar.
Do I need a smartwatch or any other hardware?
No. A phone you can prop against something is the whole setup. Nothing to wear, nothing to charge, nothing to tap once the set has started.
Is my video recorded or uploaded?
No. The pose detection runs entirely on your phone and frames are discarded as they are analysed. Nothing is uploaded and nothing is stored. It counts in airplane mode, which is the simplest proof of it — see the privacy policy.
Is there a free version?
Yes. The solo counter is free across all three exercises, with a daily allowance, and you can accept a challenge from a friend without paying or even making an account. Pro removes the limits.
Beastie is a general fitness product, not medical advice. Form feedback is about scoring reps fairly, not a health assessment.
One set. An honest number.
Pick a move, prop the phone, go. No wearable, no setup, no subscription to start — just a count you can stand behind, and a friend who probably reckons they can beat it.
