Muay Thai Coach: Combo Caller

A round clock that calls muay thai combinations out loud, so a bag session runs with the screen off, the phone set down and nothing to look at. The interval is the product. Most round timers call on a fixed beat. A jab-cross takes about a second to throw; a jab-cross-hook-low kick takes three and a half, and the bag then swings away for most of another. Combo Caller times every call from the cycle of the strikes in it plus the bag's own return, so the gap after a low kick is longer than the gap after a jab and you are never rushed into a combination you have not finished. A hundred and sixteen combinations, met in training. Numbered hands, hands into legs, the Dutch four-count, elbows and knees, clinch entries, counters and feints. They were learned from real coaches in France and in Thailand and from online courses, and every combination screen writes down the strategy behind it: why it works, who it works against and how to throw it. Thirty-one workouts, and every one that calls a combination is built on a named source. A workout with no source fails the app's own test suite, so the rule is held by the data and not by good intentions. A workout draws between five and thirteen combinations, because a pool wider than that brings a combination back about once a month and nothing is learned at that spacing. Build your own if none of the thirty-one fit. Fourteen workouts are free for everyone, along with every combination, the history and three workouts of your own. Nak Muay adds the other seventeen, the tactical ones, and as many workouts of your own as you want: one purchase, no subscription. If you had the app before Nak Muay existed, it is already yours. A new combination gets one step of preparation. Its first two calls leave off the last group, then it arrives whole, and the cut only ever falls on a group boundary: a feint and the strike it buys are one call or no call. Only the Build one combo workout adds a strike a round. A coach between the calls. Short cues in the same voice, like "shin, not foot" or "back to guard", slipped into the silences and never over a call. Choose how often, or mute any of them. It runs with the screen off. Set the phone down and leave it. The screen stays on while you want it and the coach keeps calling once it is off, through the silent switch, with the round and the clock on the lock screen. Keep your own music playing if you want; calls duck it and it comes back. It remembers what you did. Every call is logged. Fifteen weeks of history, fourteen days of bars for each combination, a round-by-round breakdown of any past session, and a CSV of the lot. What it will never do. There is no camera and no sensor, so the app makes no claim about your technique — it counts the calls it made and says so. There is no account, no sign-up and no network connection of its own: the whole thing, voice included, is on the phone. The only network traffic is the App Store's own, to check and make the Nak Muay purchase. Nothing you do here leaves the device, because there is nowhere for it to go. English and French.
