Only for iPhone
Free · In‑App Purchases
iPhone
Save your workouts as cards and start with one tap. A voice counts 3-2-1, says Go, calls every rest, and every session is logged automatically.
SolTi is a workout timer for people who train alone at the gym or at home - with a prep countdown, HIIT intervals, and a voice that counts you in.
Save each workout as a card, tap it once, and the timer runs the whole thing: prep time, work time, rest, and the next round.
Every finished session is logged automatically, so your records build up without any extra taps.
A voice that keeps you off the screen
- 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.
Prep time, then work - one unbroken flow
- 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.
Timer cards for the workouts you repeat
- 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.
HIIT and Tabata intervals
- 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.
Records, levels, and badges
- 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 and 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.
Do I need an account? No - there is no sign-up, and your records are stored on this phone.
Does the timer work with the screen off? Yes - it keeps counting, and a notification tells you when a phase changes and when you are done.
Can I switch the app language? Yes - choose English or Korean in Settings.
