TIMEROX — AN INTERVAL TIMER WITH CHARACTER VOICES

Most timers beep. Timerox talks. Underneath is a precise interval timer for HIIT, Tabata, boxing rounds, BJJ rolls, cardio, and strength. On top of it sits something other timers do not have: a small cast of character voices who count you in, call the work, and hold the pace.

Each one is a distinct personality with its own attitude and delivery, from a calm presence to a relentless one, and a deliberately mechanical AI for when that is the energy you want. You choose the voice per workout.

THE VOICES
- BJJ Coach — intense Brazilian energy, pure effort.
- Caring Coach — warm and grounded, calm support without the yelling.
- Hardcore — drill sergeant, no excuses.
- Robot — sci-fi training AI, cold and precise.
- Quiet Strength — stoic and steady, presence over volume.
- Silent — just the timer, for when you want one.

Every voice speaks English, French, and Spanish, and the interface is fully localized to match.

THE TIMER UNDERNEATH

Build any structure you need: prep, work, rest, cycles, sets, set rest, and cooldown, all configurable per workout. Eight presets are ready to go, including HIIT 30/30, Classic Tabata, EMOM 10, 5x5 Strength, Mobility Flow, Boxing Rounds, and Jiu-Jitsu Rolls. The workout editor uses color-coded steps and totals your time as you build.

Need something simpler? Quick Timer is a one-shot countdown with preset chips and custom input, for the moments you just need a clock.

BUILT FOR THE GYM FLOOR
- A live notification keeps the current phase and time remaining in your shade. Switch to music or messages mid-workout without losing your place.
- A big, high-contrast countdown you can read across the room.
- Lock the screen during a workout so a phone on the rack does not get bumped. Long-press the padlock to unlock.
- Sound and haptic cues on every phase change, both optional.
