Circuit / Tabata Timer

Number of Sets

How many times each exercise performs.

Intervals

Tap any interval to open the interval editor. Empty optional intervals are skipped.

Exercises

The list of work intervals, rotated each set. See Managing Exercises below.

Rest Between Intervals

A rest between exercises. Also used between sets when Rest Between Sets is empty.

Managing Exercises

Adding an Exercise

Tap Add Exercise at the bottom of the list.

Reordering, Moving, Deleting

Two ways to manipulate exercises.

Drag a single exercise. Tap and hold the drag handle (≡) on the row, then drop where you want it.

Cut, copy, and paste multiple at once. Tap the circle on the left of each row to select exercises in the order you want them to reappear. From the toolbar:

• Cut removes selected exercises. Paste them elsewhere to move; don't paste to delete.
• Copy keeps selected exercises in place. Paste elsewhere to insert duplicates.

Paste at the bottom of the list via the toolbar's paste button, or beneath a specific exercise by tap-and-hold + Paste.

If you can't see the toolbar, close the keyboard first.

Tabata Style

Each exercise runs all its sets before moving to the next, instead of rotating through the list each set.

Based on CrossFit's Tabata definition, not the looser HIIT-synonymous use of the term.

Randomize Order

Shuffles the exercise list, then runs the shuffled order for each set.

To reshuffle every set instead, open this URL in Safari on the device with Seconds installed:

seconds://?action=randomise-each-set&value=true

Common Properties

Name

How the timer is labeled in lists, including the sub-timer list inside compound timers. Blank names show as Unnamed Timer.

Activity

Tags the timer with an Apple Health activity. Required if you want completed sessions to log as workouts.

Alerts

Sound and haptic cues for interval transitions. Tap to change them. Inside compound timers, each sub-timer keeps its own alerts; rest intervals use the compound's.

Audio

Music or other audio for the timer. Tap to open the audio editor.

Allow Overrun

Tacks a count-up interval onto the end so you can keep training past the scheduled finish and still log the time. End the timer manually when you're done — otherwise Seconds keeps running in the background and drains your battery.

Color

Display color in the timer list. Defaults to the parent folder's color.

Notes

Scratchpad for anything you want to keep with the timer. URLs auto-link.

Preview

Sanity-check before you start. The Preview Bar at the top of the editor totals the duration; tap it for the full interval list.
