A ghost that peeks in until you rest.
One gentle rhythm for your eyes, your neck, and your water bottle — kept by a small ghost who takes it personally when you skip a break.

Really how it works: a quiet peek first, then a polite float-out, then a dramatic flop-nap. Never blocking, always dismissible.
One rhythm. Not four nagging timers.
Long screen stretches quietly cause eye strain, neck pain, and office syndrome. Pak-a-boo interrupts with a single unified schedule, so breaks feel like a rhythm rather than a barrage.
20-20-20 eye break
Every 20 minutes, look 20 feet away for 20 seconds. Mr.Boo gazes out the window with you.
Eyes + a sip
Another micro eye break with a hydration nudge attached — water never gets its own separate alarm.
The big break
Two to three minutes: stand up, drink, and follow guided office-syndrome stretches, demonstrated pose by pose.
Three escalations, none of them angry
Two eyes rise from the bottom of the page. Silent. One click to start the break — or dismiss.
Still ignoring? Mr.Boo floats fully out and asks nicely, with his own "5 more minutes" snooze.
Really ignoring? He flops down for a nap in the middle of your screen until you take the hint.
Meet Mr.Boo, Blob & Buggy
Three mascots, one job. Switch anytime from the popup — every peek, pose, and skin carries their own personality.
Mr.Boo มิสเตอร์บู
The original. A gentle ghost who takes napping very seriously.
Blob บล็อบ
A squashy little dome. Extremely soft. Zero bones, zero stress.
Buggy บักกี้
A grey tabby with his own tail, whiskers, and opinions about your posture.
Fits around how you actually work
A couple of small things that make the rhythm work with your day, not against it.
Need to lock in? Pause every reminder for an hour with one click from the popup.
Your popup shows today's screen time right alongside your break count, so you can see the whole shape of the day.
Take breaks, dress your ghost
Every day you complete at least one break, your streak grows — and your mascot earns new looks, permanently. Weekends and days off don't break your streak: if the ghost never had a reason to peek, it simply pauses.
Here's a week, sped up
Nine guided stretches, Thai-PT style
The big break rotates through simple desk stretches — each one demonstrated by your mascot with clear cues in Thai and English.
