SolTi

A spoken 3-2-1 countdown before work starts, and "Go" the moment it begins.

A voice cue each time a rest phase starts, and a cheer when the workout is done.

Vibration on every phase change, for loud gyms and quiet mornings.

Sound and vibration can be turned on or off separately in Settings.

Every timer card has a prep time: press Start, get into position, and the work time begins on cue.

The timer keeps running with the screen off; a notification marks each phase change and the finish.

Pause, resume, or stop early with big buttons made for one hand.

Save "Plank 2:00", "Rest 90s", or "Squats 0:45" as cards and start any of them with one tap.

Give every card its own color with the color slider.

Put cards in the order you like.

A HIIT timer strings several exercises together with rest in between and repeats them for as many rounds as you set.

20 seconds on, 10 seconds off, 8 rounds - the classic 4-minute Tabata is one card.

Each exercise in a HIIT timer gets its own time, so full-body circuits are easy to build.

The Home screen shows today's training as a color bar.

Records shows weekly and monthly charts, a history list by date, and totals: time, sessions, average, and streak days.

Five levels from Rookie to Master, earned with total training time, plus 9 badges to collect.

A 12-week workout heatmap shows how hard you trained week by week (Pro).

Free: up to 3 regular timer cards, 1 HIIT timer, and all records, stats, levels, and badges. The free version shows ads outside of workouts.

Pro: unlimited timer cards and HIIT timers, no ads, the 12-week heatmap, and home screen widgets (small, medium, large) that start a card right from your home screen.

Pro is a monthly or yearly subscription. The price shows in your local currency on the purchase screen.
