About this app

SolTi is a workout timer, interval timer, and Tabata timer rolled into one clean app - built for people who train alone, with a voice that counts you in. Timing rest between sets at the gym, running a home workout in your living room, holding a plank you refuse to drop - whenever your workout needs a timer, SolTi has you covered.

You know that gap between hitting Start and actually getting into position? Those lost seconds eat into every set. SolTi fills the gap with a Prep countdown: press Start, get on the mat, settle into your form - and when the voice hits "3, 2, 1," your work time begins exactly on cue.


- A voice that coaches you through

- A spoken 3-2-1 countdown before every start - get ready by ear, not by staring at a screen
- "Go" the moment work begins - put the phone down and focus on your body
- A heads-up every time a rest phase starts, so you always know where you are in the interval
- A cheer when you finish - because the last rep deserves one
- Vibration alerts for every phase change - perfect when the gym music is loud or the house is asleep
- Toggle sound and vibration separately in Settings

No more squinting at the screen mid-plank. No more grabbing your phone between burpees. SolTi tells you everything you need to hear.


- Prep and Work, one unbroken flow

- Prep time and work time run as a single sequence - the seconds you spend getting into position are part of the plan
- The Prep countdown rolls straight into work automatically - no extra tap
- Pause, resume, or end early with big one-handed buttons
- The timer keeps running in the background with the screen off, and notifies you when the round ends


- Your go-to workouts, saved as cards

- "Plank 2:00," "Rest 90s," "Squats 0:45" - save the timers you use most as cards
- Next time, one tap starts the whole workout - no re-dialing the same numbers every day
- Pick any color for every card with the color slider


- Tabata and HIIT interval timer

- Run work / rest intervals across multiple sets, all on one screen
- 20 seconds on, 10 seconds off, 8 rounds - the classic 4-minute Tabata is one card away
- Build full-body circuit training - burpees into mountain climbers into jumping jacks - with custom times per set


- Every workout logged, automatically

- When the timer ends, the session saves itself - no extra tap
- Today's bar - your day's training laid out in color across the top of Home
- Weekly and monthly charts, plus a history list grouped by date
- Totals at a glance: time, sessions, average, and streak days


- Built to keep you coming back

- Level card - 5 tiers from Rookie to Master, earned with total training time
- 9 achievement badges to collect, one milestone at a time
- Workout heatmap - your last 12 weeks of intensity in color (Pro)


- When to reach for SolTi

- At the gym - a rest timer between sets, interval training
- At home - roll out the mat and let the Prep countdown set the pace
- Morning stretch or yoga - a set time for every pose
- Plank challenge - log how long you last, every single day
- The 4-minute Tabata - short, brutal, done
