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 - even with the screen off. - 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 runs with the screen off; a notification marks each phase change and the finish - 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 thing - no re-dialing the same numbers every day - Pick any color for every card with the color slider - Tabata and HIIT intervals - 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 circuits - burpees into mountain climbers into jumping jacks - with custom times per set - HIIT keeps timing in the background even with the screen off - 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 - timing rest 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 - Free and Pro Free includes: - Up to 3 regular timer cards - 1 HIIT timer - Full workout history, stats, levels, and badges Your card list starts empty - tap Create and build your own.
