NO DISTRACTIONS. JUST INTERVALS.
FourEver is a native interval timer engineered for pure flow state - built by an athlete for anyone who would rather grind than fight a messy clock. Zero ads, zero tracking, zero subscriptions, and zero fluff.
Whether you’re hitting heavy bag rounds, Tabata sprints, EMOM sets, or custom calisthenics circuits, FourEver keeps your workout moving without getting in your way.
BUILD IT ONCE. START IN SECONDS.
• Custom Phase Control: Set Warm-Up, Work, Rest, Rest Between Sets, and Cool-Down durations down to the second.
• Built-In Templates: Tap and go with pre-configured Tabata, HIIT, EMOM, Sprints, and Boxing setups.
• Live Adaptability: Jump to any interval or skip phases on the fly when your training demands a change.
WHEN THE TIMER STARTS, THE WORK STARTS.
Put your iPhone across the room or slip it into your pocket. FourEver carries the rhythm of your session with crisp audio cues that seamlessly duck over your music without stopping the vibe.
• Background Audio Cues: Hear spoken phase names and a 3-2-1 countdown while your workout playlist keeps playing.
• Wide Landscape Display: Massive, high-contrast digits readable from across the gym or studio floor.
• Control Lock: Freeze the UI during workouts to prevent accidental taps mid-set.
• Haptic Cues: Feel the transitions even in noisy training environments.
STAY LOCKED IN - WITHOUT UNLOCKING YOUR PHONE.
Live Activities keep your total workout time remaining and overall progress visible on the Lock Screen and Dynamic Island. Full views add total sets and rounds, with controls to pause, skip, or resume.
PROOF OF THE GRIND. NEVER BREAK THE CHAIN.
Consistency is quantified. Look back on completed sessions, total rounds, and training time across days, weeks, and months.
• Keep your workout streak alive and watch your effort compound.
• Review session details and history whenever you need proof of the work put in.
LIGHT MODE. DARK MODE. ALWAYS BEAST MODE.
Designed specifically for iOS with deep OLED dark mode for late-night sessions and clean light mode for outdoor training. Fast, responsive, and easy on your battery.
100% PRIVATE & OFFLINE BY DESIGN.
• Zero Ads.
• Zero User Accounts.
• Zero Analytics or Third-Party Tracking.
• 100% On-Device Data Storage.
• Works Completely Offline - In the Gym, Park, or Ring.
From four-minute finishers to custom multi-round circuits, FourEver keeps every interval clear and every workout moving.
Build it. Start it. Never break the chain.

A NOTE FROM THE DEVELOPER
As a karate athlete, I built FourEver Timer because I needed a clean, native tool that stays out of the way and lets me focus entirely on my training. I originally created it for my own workouts, and I hope it helps take yours to the next level.

FourEver Timer just got faster to set up and easier to read mid-workout.
• New timer editor: Work, Rest and Rounds are open wheels the moment you tap Create. Spin, spin, Start. Warm-Up, Cool-Down and Sets sit right below.
• Start From: build a new timer from any timer you've saved, or from Tabata, HIIT and EMOM.
• The round count is now large and inside the ring, with the current set underneath for multi-set workouts.
• Redesigned Live Activity: your whole workout as a colour-coded timeline on the Lock Screen that keeps moving on its own, plus bigger Pause and Next buttons.
• History can now page back through previous days, weeks and months, and long totals read in hours and minutes.
• Reorder your timers by pressing and dragging a card.
• An interrupted workout is restored when you reopen the app, and your timers and history are better protected.
• The editor asks before discarding unsaved changes. You can turn this off in Settings → Confirm Actions.
• Save New Timers is now on by default, so a timer you start is kept in your library.
• A refreshed, consistent look across Timers, History and Settings, plus fixes for cues, haptics and translations.
