Intervals

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.

Duration

The length of the interval, in 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.

Color

The color the timer screen shows during the interval.

Behavior

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.
