What this timer is for
Interval runs a plan of timed steps in order — study blocks and breaks, exercise rounds, a rehearsal routine — and moves through it for you.
Routines, sets and stages
A routine is the whole plan. It is made of sets, and each set is a list of stages. A stage is one timed step with a name and a duration; a set can repeat, so its stages run again in order.
Build routines in the routine builder: name the routine, add sets, give each set its stages and a repeat count. Reorder by dragging or with the move controls. Save to keep the routine; your saved routines are listed in the timer settings.
Stage names are yours — they appear in the timer, in announcements and in exports exactly as you typed them.

Starting a session
Choose a routine in the timer settings and press Start. When a stage finishes naturally, its end cue plays and the next stage starts automatically. Stages, repeats and sets follow in order until the routine is complete.
Skip moves to the next stage at once; Previous returns to the stage before. Both keep the timer running if it was running.
Pause and resume
Pause holds the current stage; Resume continues from the same moment.
Reset and restart
Reset returns to the first stage of the routine. The routine itself is unchanged.
Progress
The ring shows the whole routine, start to finish, while the digits count down the current stage.
Marks on the ring are boundaries: a short mark where one stage ends and the next begins, a longer mark where a set ends. Each mark sits exactly where that boundary falls in time, so a long stage takes more of the ring than a short one.
A very large routine would turn into a comb, so the ring adapts: up to eight boundaries are all drawn; up to twenty, stage marks are drawn lighter; beyond that only set marks are shown, so the ring stays a map rather than a scale.
Stage colors
Every stage can carry a colour. In the routine builder, under Routine appearance & sounds, choose how the ring uses them.
One color: the ring uses your saved Progress Color from Appearance, exactly like every other timer. Stage colours are kept but not shown.
Stage colors: the ring takes the colour of the stage that is running — its own, or the routine's default if it has none. Your Progress Color stays saved and still applies to the other timers.
Progress styles
Appearance offers several progress styles. Ring, Horizon, Bar and Perimeter draw the same progress in different geometries.
Wave draws the completed part of the ring as a gentle ripple while the remaining track stays calm; it settles briefly when a stage changes.
Glass draws the ring as layered, lit material — a soft bed, a translucent core and a highlight. Thickness and presence apply to every style.
Sounds and voice
Cues mark the routine's moments: a stage start cue, a stage end cue, a set complete cue and a routine complete cue. Set the defaults in the routine builder; a stage can use the routine's sounds or its own.
Voice announcement, under Sound & Alerts, says the stage name aloud in this device's own voice when a stage begins. It is off by default and needs a browser that supports speech.
Customization
Appearance sets progress style, thickness, presence and color, the clock face and font, and the background. A running routine locks structural and appearance edits. Sound choices remain editable and apply to the next alert.
Focus Mode and fullscreen
Focus Mode quietens the workspace around the timer; Fullscreen gives it the whole screen. Neither pauses or changes the routine.

Common questions
- What is a set?
- A group of stages that run in order. Give a set a repeat count and its stages run that many times before the next set begins.
- What happens when I press Previous?
- The timer goes back to the start of the previous stage. If it was running it keeps running; the ring moves back to that stage's boundary.
- Can every stage use a different colour?
- Yes. Give each stage its own colour in the builder and set the routine to Stage colors. Stages without a colour use the routine's default.
- Why are some stage ticks hidden?
- On a large routine the ring shows only set boundaries, or a lighter set of stage marks, so the marks stay readable. Every mark that is drawn is in its true place.
