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

Read full description

You were born with roughly 4,000 Saturdays. Some are already gone. How many are left? Saturdays Left answers that question - personally, honestly, and with a purpose. Enter your birthday, walk through a quick health profile, and see your number. Not a generic statistic. Yours. Then watch it move. YOUR CHOICES COMPOUND Log your daily habits — exercise, diet, sleep, drinks, smoking — and watch your Saturday count rise or fall in real time. Good days add time. Hard days subtract it. Over weeks and months, the compound effect becomes impossible to ignore. PEOPLE YOU LOVE Add the people who matter most. See how many Saturdays you have left with Mom, Dad, your kids, your partner. Then see this: "If you see Mom once a month, you have about 221 dinners left together." That number changes how you spend your weekends. PLAN YOUR SATURDAYS A bucket list tied to your actual remaining time. Set dreams, assign target dates, and watch the runway between now and then. "You've completed 3 of 12 dreams. 1,847 Saturdays to go." SEE WHERE YOUR TIME GOES Enter your weekly screen time, commute, and overtime hours. Saturdays Left shows you how many of your remaining Saturdays those habits consume — and exactly how many you'd get back by cutting one hour a day. FAMILY TIMELINE A visual timeline showing when your kids leave home, when parents reach milestones, and where your lives overlap. The relationships that matter most, mapped against finite time. TRACK YOUR RITUALS Define the moments that matter — family dinner, date night, park with the kids, calling Mom. Track which ones happened each Saturday. See your completion rate and streaks. "You've had family dinner 34 of the last 52 Saturdays." SHARE YOUR NUMBER Generate a beautiful image of your Saturday count and share it. "I have 1,847 Saturdays left. What are you doing with yours?" PRIVATE BY DESIGN All data stays on your device. No accounts. No cloud. No tracking. No analytics. Your mortality is nobody else's business. Saturdays Left won't add a single day to your life. But it might change how you spend the ones you have.
