Real strength workouts, written for the gear you've got and the 30 minutes you have. Open Kronos and today's session is ready: exercises, sets and the weights filled in, built for the equipment in front of you and the minutes you named. Different every time, shaped to your gear, your time, and how you actually feel today. You don't need more motivation. You need fewer decisions. IT ALREADY KNOWS • It already knows what's at your gym. • It already knows you only have 20 minutes. • It already knows you skipped Tuesday. • It already knows you hated lunges last time. • It already knows you've done legs twice this week. So you don't have to. HOW ONE TAP WORKS BUILT AROUND YOUR ACTUAL GEAR. A pair of dumbbells, a full gym, or nothing at all: tell Kronos what you have and it never writes a workout that needs a cable machine someone else is on. It fills in the weight, too, instead of leaving you a blank. HOTEL ROOM? HOTEL WORKOUT. Save your spots: gym, home, hotel, the park. Switch in one tap and the workout reshapes itself. Flag an injury once and it plans around that too. SWIPE EXERCISES, NOT EX'S. Love it, like it, meh, never again. Every swipe trains the next workout. PROGRAMS THAT BEND. Seventeen programs, 2 to 8 weeks each, written for your gear and shaped to your week instead of the other way round. The first session of every one is free. Any day you'd rather not be on one, build a single session instead. TRAIN WITH YOUR CREW Start a challenge, drop the code in the group chat, and every finished day puts your name on the Wall beside theirs. Pick a shape: a daily target, a ladder, a weekly max test, or just show up. Wildcards cover a missed day, streaks carry, and nobody gets a notification about your rest day. It's the part that makes people keep going, and it isn't a leaderboard for strangers. It's five people you already know. A BIG CALM TIMER We tell you what's next; you just lift. No tapping mid-set. Then swipe: right to keep, left for never again. Benchmarks are in there too. Cindy, Murph, and 42 more, each one scaled to the kit you actually own instead of the kit the workout assumed. LOGGING, WHEN YOU WANT IT Log a set if you want the number. Skip it if you don't. Your week, your lifts, and your history are there when you go looking, and never the price of getting a workout. PLUS A FREE INTERVAL TIMER. ACTUALLY FREE. HIIT, Tabata, EMOM, AMRAP, plus full custom intervals. Save unlimited presets. The screen stays awake, the cues mix over your music, and there are no ads. No account needed, no "Pro timer" upsell. Not now, not ever. WHAT WE BELIEVE Variety beats optimization. Constraints are features. Decisions are willpower taxes. Today's mood matters. Adherence beats intensity. Fun is a strategy. A B+ workout four days a week beats an A+ workout once. Every time. KRONOS PRO Free is the interval timer, forever, plus five workouts written for your gear and the first session of every program. Pro is the rest: a new workout every day you open the app, every session of all 17 programs, your whole history scored, up to 10 challenges at once, and crew insights. Prices are shown in the app and may vary by region. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period.

A clean, practical workout timer for anyone who trains. Intervals, rounds and rest — set in seconds, and big enough to read from across the room. Ready-made timers for boxing, MMA, HIIT and yoga. Hundreds of workouts already written out. A log that fills itself. No ads. No account. EIGHT TIMERS FOR TIME: counts up, with an optional time cap. INTERVAL: work and rest, in as many sets as you like. EMOM: every minute on the minute, with a movement for each minute. AMRAP: as many rounds as possible, counting down. TABATA: 20 seconds on, 10 off, 8 rounds, all adjustable. DEATH BY: one more rep every minute, until you can't. FIGHT GONE BAD: stations, work and rest, set by set. STOPWATCH: a plain clock, counting up. BUILD YOUR OWN, AND KEEP IT Every timer has its own page. Set the rounds, the work and the rest, name the movements, and press START. Save the ones you come back to and they are waiting on the home screen — and on your watch. READY-MADE, BY SPORT Boxing and MMA rounds on the bell. HIIT and Tabata ratios. Yoga holds with the transitions between them. Open one and press play; there is nothing to set up. THE WORKOUTS, WRITTEN OUT Sixty classic benchmarks — The Girls and The Heroes, from Fran and Cindy to Murph — with their time caps and movements already in. Thirty more for Halloween and twenty set on South Beach. Pick one and run it. BUILT TO BE READ ACROSS THE ROOM The screen fills with the time, the phase and the movement by name, inside a glowing aura that changes colour as work turns to rest. Light or dark, whichever you prefer. Turn the phone on its side and it splits in two: the clock on one half, the round on the other. CUES YOU CAN HEAR Beeps on 3-2-1 into every interval, a long tone into work, a lower one into rest, and a triple at the end. They mix with your music instead of turning it down, and they keep going when the screen locks — on the Lock Screen and in the Dynamic Island. A LOG THAT FILLS ITSELF Every workout you finish lands in your log, on a month calendar. Nothing to write down, nothing scored, no streak to keep up. Swipe a row to tick it off or delete it. Your history syncs through your own iCloud, and finished workouts can be saved to Apple Health. ON EVERY SCREEN YOU OWN iPhone, iPad, Mac and Apple Watch, with the same timers and the same log on each. Connect a TV by cable or AirPlay and the clock fills the big screen while your phone keeps the controls. PRIVACY No ads and no tracking. Anonymous usage statistics show us which timers get used, and they cannot identify you. Your workout history stays in your own iCloud, which we cannot read. EVERYTHING INCLUDED Every timer, every workout, the log, iCloud sync and Apple Health are included. There is an optional tip in Settings, and it unlocks nothing.
