About
Phaseline is an interval timer built for the gym floor. Set it up in two taps, put the phone on the bench, and train — every phase is readable from across the room, every cue lands on time, even with the screen locked and your music playing.
EVERY FORMAT YOU TRAIN
• Intervals — work and rest, rounds and sets, warm-up and cool-down, exercise names per round
• Tabata — 20/10 × 8, multiple blocks, or the classic 4:00
• EMOM — every minute on the minute, with rotating stations
• AMRAP — count rounds with one big tap target
• For Time — with an optional time cap and minute markers
• Rest — a rest timer between sets that counts the sets and keeps counting when you go over
• Stopwatch — with laps
• Custom — build your own sequence of steps, blocks and sets
NEVER LOSES TIME
Phaseline's clock is anchored to real time instead of counting ticks, so it doesn't drift, pause by itself or reset. Cues play on time when the phone is locked and over your music or podcasts. If iOS closes the app mid-workout, backup notifications (when you allow them) still arrive on schedule, and the workout is right where it should be when you come back.
THE LOCK SCREEN COMES FIRST
A Live Activity shows the current phase, the time left and what's next on the Lock Screen and in the Dynamic Island — with Pause, Skip, +15 s and Round buttons that work without unlocking. It also appears in the Apple Watch Smart Stack.
A REST TIMER THAT RINGS
Turn on Ring as alarm and your rest ends with a real alarm, even in Silent mode. Start a rest from the Action button, Control Center or Siri: "Rest for 90 seconds in Phaseline".
READABLE AT THREE METRES
The whole screen takes the colour of the phase — work, rest, get ready, cool-down — with huge digits fitted to the display. Turn the phone sideways for an even bigger wall clock.
MADE FOR SWEATY HANDS
Large controls, no fiddly gestures, a lock that keeps a towel from pausing your workout, and clear voice prompts: "Ten seconds", "Last round", "Rest. Next: burpees".
YOUR HISTORY, YOUR DATA
Finished workouts are saved with rounds, splits and notes. Export them as CSV whenever you like. There's no account, no ads, no tracking and no data collection — everything stays on your iPhone.
ACCESSIBLE BY DEFAULT
