SET IT. LOCK IT. TRAIN. FourEver is the interval timer you set once and then forget about. Build your session, put the phone in your pocket and go. Sounds, voice cues and your AirPods keep the pace, so you never touch a sweaty screen mid-set. Built by a karate athlete who got tired of fighting messy timers between rounds. Tabata, HIIT, EMOM, boxing rounds, sprints or your own "Burpees Were A Mistake" circuit: FourEver runs it. NOD TO SKIP THE REST (PRO) Wearing AirPods? Nod twice near the end of a rest and the next interval starts. Shake your head and you get a little more rest. No hands, no phone, no excuses. Well, maybe one. HANDS BUSY? ASK SIRI (PRO) "Start Leg Day in FourEver." "Pause FourEver." "Next interval in FourEver." Start, pause, skip and end by voice, or ask how your week and your streak are going. APPLE WATCH & HEALTH (PRO) Leave the phone in the bag. The Watch app runs your timers on its own or follows your iPhone, taps your wrist at every change, and saves each workout to Apple Health with your heart rate, so it counts toward your Activity rings. NEVER UNLOCK YOUR PHONE AGAIN • Live Activity on the Lock Screen and in the Dynamic Island: the current interval, what's next, Pause and Skip. • Spoken phase names and a 3-2-1 countdown that lower your music instead of stopping it. • Haptics for noisy gyms. Big digits you can read from across the room. Lock the controls so a pocket can't pause you. • A call mid-workout? The timer pauses, and with headphones in, a 3-2-1 brings you back when you hang up. NAME EVERY MOVE (PRO) Build circuits like "Push-ups → Squats → Plank" and FourEver says each exercise out loud as it starts. Your brain stays on the floor with you. BUILD IT ONCE. START IN SECONDS. • Templates: Tabata, HIIT 30/30, EMOM, Boxing, Sprints. • Wheels for every value: work, rest, rounds, sets, warm-up, cool-down, rest between sets. • The whole session on one timeline before you start. • Share a timer by link or QR code. Suffering is better together. PROOF OF THE GRIND Streaks, rounds and training time by day, week and month. Don't break the chain. EVERYWHERE YOU ARE (PRO) Widgets, Control Center, the Action Button, and iCloud Sync for your timers and history on every device. FREE AND PRO Free forever: the full timer, sound and voice cues, Live Activity, history and streaks, and up to two saved timers. FourEver Timer Pro unlocks head gestures, Siri, the Apple Watch app, exercise circuits, unlimited timers, widgets and controls, and iCloud Sync. Monthly or yearly, with a free trial to start. PRIVATE BY DESIGN No account. No ads. No tracking across apps. Your timers and history stay on your devices and in your own iCloud. Anonymous usage data and crash reports help improve the app, and one switch in Settings turns them off. The timer works offline: gym, park or basement. In English, German, Russian and Ukrainian, voice cues included. Siri works in English, German and Russian. Head gestures need AirPods with motion sensors (AirPods 4, AirPods Pro 2 or later, AirPods Max). --- A NOTE FROM THE DEVELOPER I'm a karate athlete, and I built FourEver because I wanted a timer that stays out of the way. It started as a tool for my own training. I hope it makes yours easier, and a bit more fun. — Alex --- Subscriptions renew automatically until cancelled.
