Selo – Interval Timer
10,000 Hours · Pomodoro · HIIT
Free · In-App Purchases
Two wheels, tap Start: Move, Rest and Sets switch on their own, cue tones keep going when locked. Every set counts toward 10,000 hours, now on a new data page.
Selo is an interval timer that adds every session up toward 10,000 hours.
• Two wheels: set Move, Rest and Sets, tap Start — HIIT, Tabata, boxing rounds, Pomodoro
• Cue tones keep going with the screen locked; countdown on the Dynamic Island and Lock Screen
• Turn the one you miss most into a living sticker, watching you grow stronger (Selo Pro)
• Save sessions to Apple Health as workouts
• Opens within 2 seconds, even on a six-year-old device
• No account, no ads, no data collected
Selo Pro, a one-time purchase rather than a subscription, adds voice cues, the data page (week, month, year, streaks, distance to 10,000 hours), more task cards, dozens of ring materials (wood, leather, jade, stained glass), stickers, photo backgrounds, colours, more finish sounds and iCloud sync.
It is a truth universally acknowledged, that every hero in want of greatness must be in want of a good companion.
Meet Selo.
Simple to use. Powerful underneath. A joy to come back to.
Turn the one you miss most into a living sticker — someone is watching you grow stronger, someone is cheering you on. Add smart voice cues, and even with the screen off, that voice never goes dark.
Training? Selo. Studying? Selo. Everything you practice? Selo.
Ten thousand hours makes a master. Selo keeps a careful record of every one — proof of how far you've come. Your data is yours alone: it syncs only to your own iCloud and Apple Health.
We collect no data. None.
