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.

Verdict
The clearest difference is price: Just Calendar at Free against Silo's $1.99. Just Calendar also leads on rating (4.3 vs 3.4) and update cadence (every 5 days vs every 3 weeks). Silo's advantage is iOS requirement (13.0 vs 18.0). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Just Calendar is free to download; Silo costs $1.99 up front. Silo sells 1 one-off in-app purchase and Just Calendar sells 12 in-app purchases, starting at $1.49 per 3 months. Whichever you choose, the download price is not the number that matters.
Just Calendar holds the better App Store score, 4.3 against 3.4. That said, the two scores are not equally well evidenced: Just Calendar has 295 ratings behind it against 10, so its average is the more settled of the two. Written reviews split almost evenly too, at 36% and 37% positive.
Silo ships an update every 3 weeks, Just Calendar every 5 days. Both last shipped on November 2, 2026.
