Build an interval workout, then run it with everyone in the room. Kuramo is an interval timer for runners. You build a routine out of phases: a warm-up, then cycles of hard and easy repeated as many times as you like, then a cool-down. During the run one ring sweeps the interval you are in, and a bell tells you what you just entered without you looking: two strikes for a hard interval, one for easy or rest. RUN IT TOGETHER, WITH NOTHING IN BETWEEN Tap host, choose how long until the start, and show the code. Everyone scans it and every phone runs the same session from the same instant. There is no account, no server and no internet involved. The QR code carries the entire workout and the exact moment it begins, so each phone works out the current interval from its own clock and nothing needs to pass between them ever again. It works in a basement gym with no signal. Someone scanning two minutes late is not behind. They land on the interval everybody else is in, with the right time remaining. BUILT FOR SOMEONE RUNNING A CLASS Nobody can pause a shared session or steer it off course. Once it starts it runs, the way a class does. Pick how long until the start, from thirty seconds to ten minutes, so people have time to get on a treadmill. The screen tells you when the session ends before you commit to it. PIN A NOTE TO ONE EXACT REPETITION Add a short cue to a single repetition and it takes the label under the ring when its moment comes, buzzes, and is read aloud if you want it spoken. Cues travel inside the code, so everyone who joined gets them too. IT KEEPS RUNNING Bells, cues and haptics keep firing with the phone pocketed and the screen locked. Back out to the routine list and a bar keeps the run going at the bottom of the screen. YOUR DATA STAYS ON YOUR PHONE Nothing is uploaded, because there is nowhere to upload it to. No accounts, no analytics, no tracking, no third-party code of any kind. Your routines are a file on your device. A workout leaves your phone only inside a code you choose to show someone.

Kuramo looks different, and reads from further away. THE RUN IS A COLOUR The interval you are in now fills the screen: red for hard, orange for easy, green for rest. The countdown is set on it in black, in a tall condensed face that fits bigger numbers into the same width, so it reads from the far side of a track. THE WHOLE RUN, TO SCALE Under the countdown is a strip of every interval in the run. Each one is as wide as it is long and as tall as it is hard, and it darkens behind you as you go. Tap it for the full program. START FROM HOME The routine you ran last sits at the top of the home screen with a start button on it. One tap and you are in the get-ready. The rest are listed under it, each with its length and the day you last ran it. A PLANNER MADE OF THE SAME PIECES Every phase in the planner is the block of colour it will be when you run it, with its time on it. A routine's length no longer counts the ten second get-ready, so 4:00 of Tabata says 4:00, on the home screen, when you finish and in History. ASKS FIRST Deleting a routine, closing a run from the bar on the home screen, and hosting or joining while a run is going all ask before they throw anything away. Editing the routine you are running pauses it, and it picks up where you left it. FIXES A run is kept in History even when the phone puts the app away while it is paused. Music comes back up when a call cuts into a bell. A code for a session that has already ended, or that starts hours from now, is turned down with a note to check your phone's clock. VoiceOver reads times as lengths and says out loud when something is refused. THEMES Amber, Rose, Steel and Iron. Ultraviolet is retired: beside a red interval it was too loud. If you had it on, you are back on Amber.
