Workout and interval timers
A workout timer calls your work and rest intervals out loud so you never count reps and seconds at the same time. Tickline's interval timers are free, loud, and work on a phone at the gym without an app install.
Choose the structure your session uses — fixed work/rest rounds for HIIT and Tabata, a running clock for AMRAP, a minute cue for EMOM, or a single hold for planks and cold plunges. Voice cues announce the last 10 seconds so you can keep your eyes off the screen.

Frequently asked questions
What's the difference between HIIT and Tabata?
Tabata is one specific HIIT protocol: eight rounds of 20 seconds work and 10 seconds rest, four minutes total. HIIT is the wider category, where you pick the work and rest lengths yourself.
Will the timer be loud enough in a gym?
Pick the beep or gong alarm and turn on voice cues. The alarm loops until you dismiss it, so a missed round change isn't possible.
Can I use these timers on my phone offline?
Yes. Tickline installs as a Progressive Web App and every timer runs locally, so it keeps working with no signal in the gym basement.
