Intervals
The building block of every timer. Tap an interval inside a timer editor to set its duration, name, color, and behavior.
Core
Name
The label shown during the interval. If a text-to-speech alert is assigned, it's the text that's spoken. Defaults to Unnamed Interval.
Include the token $(round) to insert the current interval number.
Duration
The length of the interval, in HH:MM:SS format. You can enter 0:90 — Seconds normalizes it to 1:30 when you leave the field.
An interval is included in the timer only if its duration is greater than zero, or Count Up Indefinitely is enabled.
Color
The color the timer screen shows during the interval.
Behavior
Count Up Indefinitely
Counts down from the duration as usual, then keeps counting up past zero. If the duration is already 0:00, it counts up immediately. The timer doesn't advance until you tap the next interval manually.
Exclude From Count
Keeps the interval out of the running current / total intervals display — useful for warmups, cool-downs, and rests. Doesn't affect time elapsed or time remaining.
The built-in templates use this: a HIIT timer with 3 sets, a warmup, and a cool-down has 7 intervals in total, but you only care about the 3 high-intensity ones, so the rest are excluded.
Halfway Alert
Plays an extra alert halfway through the interval. Only available with text-to-speech and beep alerts.
Splits
Split Interval Left/Right
Replaces the interval with two halves of half the duration each. Each half is labeled — Interval Name Left and Interval Name Right by default. Useful for exercises that work each side separately.
Pause Between Sides
With Split enabled, adds a rest between the two halves so you can switch sides.
First Half
Customizes the label appended to the first half. Defaults to Left.
Second Half
Customizes the label appended to the second half. Defaults to Right.
Audio
Audio
The audio assigned to the interval. Tap to open the audio editor.
Reduce Audio Volume
Lowers the volume of external audio (music, podcasts) for the entire interval, instead of just during alerts.
Beats Per Minute
A metronome beep throughout the interval. 60 = one beep per second, 120 = one beep every half-second.
