Interval training
What every part of the interval execution screen means, and what the app will do on its own.
Read before your first session
Read the screen
The current segment fills the display: what you’re doing, the target, and time or distance remaining. The next segment previews below it, so a pace change never ambushes you mid-stride.
A small spec badge in the corner, SEG 3/8 · 400 M, shows where you are in the workout, so you always know how much is left without counting in your head.
Cues and the countdown
Segments advance themselves; you don’t tap anything to move from one to the next. Each event, a warmup ending, a rest starting, a hard effort beginning, has a distinct sound and haptic, and a 5-4-3-2-1 countdown leads every transition. Cues fire whether the app is backgrounded or the phone is locked, so you can put the phone in an armband and forget it’s there.
Live Adjust
Too hot or too easy? Tap Adjust to change the current target mid-segment, and choose the scope: just this segment, or every remaining one like it in the workout. The change is logged as a deviation, not papered over, so your history still shows what the plan originally called for alongside what you actually did.
- Tap Adjust on the execution screen.
- Set the new target (pace, incline, resistance, or zone).
- Choose This segment only or All remaining segments like this one.
- Confirm. The change takes effect immediately and is recorded as a deviation.
Distance segments
A 400 m segment ends when the distance does, not when a timer guesses at your pace. Machine telemetry supplies the distance when a paired machine is running the segment; otherwise the phone’s GPS does, outdoors.
Zone drift
If your heart rate leaves the segment’s target zone, a calm amber banner says so and a haptic nudges you. No alarms, no red flashing. It’s information, not a verdict on the workout.
No smart machine?
Working out on a machine Parameter can’t control, or with no machine at all? Open the console entry view: the whole workout flattened into a numbered step table of time, speed, and incline. Key each step into the console yourself as it comes up, in order, and Parameter still tracks where you are in the workout for logging and history purposes.
