Silo: Focus & Study Timer
Pomodoro timer for Apple Watch
$1.99 · In-App Purchases · Designed for iPhone
Silo is pomodoro-style timer built for Apple Watch. Focus and break sessions are guided by subtle haptics on your wrist—no sound, no interruptions, no distractions.
It works quietly in the background, keeping you on track without pulling you out of the moment. Perfect for libraries, offices, meetings, or anywhere silence matters.
When you've got stuff to do, getting started is the hardest part. With Silo, a tap on your wrist tells you when to focus, when to take a break, and when to return. No buzzing phone. No noisy alerts. Just calm, intentional cues that keep you in the flow.
FOCUS–BREAK-REPEAT (POMODORO)
Work in 25-minute focus sessions with 5-minute breaks in between.
1. List your top tasks for the day
2. Tap FOCUS on your Apple Watch (or iPhone)
3. Haptics tell you when to break—and when to return
4. Repeat and stay in the zone
Structured breaks between periods of focus improve productivity and reduce mental fatigue. Having this flow on your wrist makes it effortless to stick with.
