About

Kronos Studio

Features
Read full description

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. Manage or cancel anytime in your App Store account settings. Terms: https://getkronos.app/terms Privacy: https://getkronos.app/privacy Most fitness apps make you a workout plan. Kronos makes you a person who works out. The best workout is the one you'll actually do.
