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. “To add something to your daily life without intrusion or complication—that’s what the Apple Watch is about, and this app does a great job of that.” — Apple WatchCast Podcast FEATURES • Apple Watch-first focus timer • Pomodoro-style focus and break sessions • Gentle haptic alerts on your wrist • Adjustable timer intervals on Apple Watch and iPhone • Pause and resume anytime • Quiet, distraction-free design • Great for silent environments • Works great with Airplane Mode SILO PRO • Apple Watch Complications • Plan your day with tasks and reminders • Assign tasks to focus sessions • Mark tasks complete • Custom focus presets • Track daily and weekly focus stats • iCloud sync for tasks and stats Support: support@silofocus.com Terms: silofocus.com/terms Privacy: silofocus.com/privacy
Focus Proof
Read full descriptionHide full description
Every focus app measures time. Focus Proof measures whether you did what you said you would. You don't just start a timer. First you write one line — "By the end of this, I will have _". Then you focus. And when the clock runs out, Focus Proof asks the only question that matters: did you? FOCUS RECEIPTS Every session prints a small, beautiful, collectible receipt — your intention, your focus time, the time of day, and a KEPT or MISSED stamp. Share the ones you're proud of. Keep them all. A missed receipt is still an honest one: you showed up and told the truth. FOLLOW-THROUGH RATE Not hours logged. Not sessions counted. The percentage of promises you kept — a number no other focus app owns, and the one you'll actually care about. Streaks count days you kept your word, not days you sat there. BUILT FOR THE PROMISE • Intention-first: no session starts without one • An immersive, candle-lit timer that stays out of your way • Wall-clock accurate — backgrounding never breaks a session • False starts (under 2 minutes) never count against you • Finish early when the thing is done — honesty cuts both ways PRIVATE BY ARCHITECTURE No account. No sign-in. No analytics of our own. No server. Your intentions and receipts never leave your device — we couldn't read them if we wanted to. The free version is supported by ads — never on the question at the end, never on the receipt as it prints. Pro removes them. FOCUS PROOF PRO — one price, forever The core experience is free and complete: unlimited sessions, the Classic receipt, your follow-through rate, streaks and 7-day stats. Pro removes the ads and adds six more receipt styles (Boarding Pass, Vintage Ticket, Vinyl Label, Polaroid, Blueprint, Telegram), five more accent colours, your live promise on the Lock Screen, in the Dynamic Island and on your Apple Watch, your golden hours, the 30-day trend and how long your sessions really run — for a single one-time purchase. No subscription, ever. An app about keeping promises doesn't rent them back to you. Make one small promise today. Keep it. Print the proof.

Verdict
The clearest difference is price: Focus Proof at Free against Silo's $1.99. Focus Proof also leads on update cadence (every 4 days vs every 3 weeks). Silo's advantage is ads (none vs shown) and iOS requirement (13.0 vs 26.0). On in-app purchases and device support there is nothing between them.
