An interval timer that does one thing well and doesn't drift, doesn't track, doesn't ask you to subscribe to keep using it. Build any sequence of work, rest, and prepare steps. Press start. Beeps land exactly when they're supposed to — even on the lock screen, even with music playing. We made it because we got tired of timers that lost the count mid-set. Free. No ads. No subscriptions. No analytics SDK in your pocket. WHAT'S INSIDE Build the train you'll actually run Three step types (work, rest, prepare). Any duration, any order. Tabata, EMOM, boxing rounds, CrossFit WODs, mobility, breathwork — the same three pieces, your sequence. Your last train auto-loads when you open the app. Your own beeps, on every phase Sixteen built-in sounds, plus custom cues per phase. Two kinds of cues: single (once, X seconds before the end) or recurring (every X seconds). Recurring cues are unrolled into an exact schedule before the timer even starts. The trains you actually did Every finished train is auto-saved with a colored timeline showing every work and rest segment exactly as you ran them. Three numbers at the finish — sets, time, work time. Tap any past train to re-load and re-run it in two taps. On your wrist, when the phone's away The Apple Watch companion app runs trains from your wrist with two modes — Basic, for a single round, and Interval, for the full work / rest / prepare sequence. The digital crown sets durations. Tap the lock to keep a sweaty palm from pausing mid-set. And you don't have to watch the screen. A haptic tap on your wrist tells you when the current step is ending and the next is starting. PRIVACY, FOR REAL Everything — your sequences, your history, your custom sounds — lives on your device. There is no server, no account, no sign-up. The app ships with zero analytics SDKs, zero crash reporters, zero advertising identifiers. We do not share data with anyone, because we do not collect it in the first place. PERFECT FOR · HIIT, Tabata, EMOM · Boxing rounds, MMA, kickboxing · CrossFit, AMRAP, time-capped WODs · Mobility, stretching, yoga flows · Breathwork (Wim Hof, box breathing, 4-7-8) · Lap timing, climbing intervals · Anyone who counts seconds for a living WHO MADE THIS Two people, with coffee and a barbell. We use the app every Tuesday, Thursday, and Saturday. If we find a bug, we fix it the same week — not in next quarter's roadmap. If you have a feature in mind, write to us. One of us will read it. — Just Two hi@justtwo.co

Set it, start it, get to work. EM:OM is an interval timer for people who actually train. Kettlebell circuits, EMOM, Tabata, HIIT, grip repeaters, boxing rounds, or one long block. No clutter, no accounts, no ads, no tracking. READ IT FROM ACROSS THE GYM The countdown fills the screen in the color of the phase: volt for work, blue for rest, amber for the lead-in, red for the last few seconds. You can check the clock mid-set without walking over or squinting. Turn your phone sideways and it goes bigger still. SIX WAYS TO SEE THE CLOCK Steady keeps a dark screen and lets the number carry the phase. Tide fills and drains with the clock, so the level is the timer. Four more come with Pro: Tally gives every second its own cell, Ropes closes a ring in as the round runs out, Glow heats the whole screen toward the switch, and Lanes lays your whole workout out as columns. CUES THAT MIX OVER YOUR MUSIC Beeps and haptics fire right over Spotify, Apple Music or a podcast. Nothing pauses. They keep working on silent and with the screen locked, so you never miss a switch. Warning beeps count you into every change. BREATHE THROUGH THE REST During rest the countdown slowly swells and settles, six breaths a minute. Recover on purpose instead of scrolling. Turn it off any time. BUILT THE WAY YOU TRAIN Interval, EMOM, Tabata, a single block, or a custom circuit where every exercise is its own mini timer with its own work, rest and rounds. Name them, save them, start them in one tap. CHAIN TIMERS INTO ONE RUN (PRO) Programs link your saved timers back to back: warm-up, workout, finisher, with no tapping in between. PLAN YOUR WEEK (PRO) Assign workouts to days and let EM:OM tick them off from your history. A simple repeating template. No streaks, no guilt. ON YOUR WRIST (PRO) Run any timer from Apple Watch with a phase ring and a tap on every switch, so your phone can stay across the gym. Follow your rounds from the lock screen and Dynamic Island. FREE AND PRO Free: up to 5 saved timers, the Steady and Tide styles, every timer type, all the cues, and iCloud sync. Pro is a one-time unlock, no subscription: Tally, Ropes, Glow and Lanes, Programs, Weekly Plan, Apple Watch, Live Activity, voice countdown, unlimited timers, and workout history. Your timers and settings sync through your private iCloud on every plan, including free.
