📝 About this app
Silo is a Pomodoro-style focus timer built for Apple Watch and iPhone.
It uses subtle wrist haptics to guide focus and break sessions without loud alerts, distracting notifications, or constant phone checking. Perfect for students, people with ADHD, deep-work professionals, and anyone who wants a calmer way to stay on track.
Silo is especially powerful on Apple Watch: a tap on your wrist tells you when to focus, when to take a break, and when to return. It’s ideal for libraries, offices, meetings, and anywhere silence matters.… View full description on the official store →

★★★★★ Feedback
- the way the subscription is present is a turn off. Find a way that is less frustrating to new users. I spent 5 minutes trying to figure out the features only to realize they can’t be interacted with at all. I thought the app was broken.

★★★★★ Great watch app
Free version is great and met all my Pomodoro needs!…

★☆☆☆☆ Subscription trap
No complications without a subscription.
No sync between watch and phone.
One star. I don’t like “creative” descriptions that avoid the truth.…
★☆☆☆☆ Waste of a dollar
I purchased this app for a dollar, and as soon as i opened it, it wouldn't let me do anything taskwise unless i pay for a monthly subscription! Plus, the pomodoro timer does not show you the current time (not even sure if its working),…

About this analysis
Why low confidence: only 10 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Silo: Focus & Study Timer is a early-stage iOS app in the productivity space with weak public traction — only 10 ratings, no founder-verified MRR, and not ranked in any monitored grossing chart. The app appears to be monetised, but public signals are too sparse for a precise revenue estimate.
Bottom line: treat all revenue, audience and acquisition-value numbers on this page as directional only — not founder-verified facts.
