Every trick here is broken into an ordered run of beats: the setup, the moment of misdirection, the move itself, the reveal, and the reset. Beside each beat two columns sit apart, one for what the audience is looking at, one for what your hands are actually doing. Nothing counts as learned until you put the beats back in order yourself and point to the exact instant the attention is pulled away. There are 48 tricks across six families, covering cards, coins, rope, mentalism, stage pieces and pure misdirection. The second half of the app exists to stop all of that from fading. Tap along to a target tempo and read your drift in milliseconds, rebuild a cue sequence against a countdown, or drag two handles around a ring of seats to mark the arc where the move would be visible. Practice away from the phone, come back, and log the attempt honestly as clean, flashed or dropped. All three carry the same credit, because what gets counted is turning up again. Confidence in a trick cools on its own, so the call board keeps reordering itself around whatever has gone quiet longest. Once a handful of tricks hold up, pin six of them into a running order and the reading will flag a repeated prop, two neighbours from the same family, or a pair of angles that fight each other. Everything stays on the device. No account, no ads, no network.
