# Powertime vs Olarm

The clearest difference is rating: Powertime at 5.0 against Olarm's 3.9. Powertime also leads on iOS requirement (11.0 vs 15.1). Olarm's advantage is update cadence (every 3 weeks vs every 3 months) and review sentiment (54% vs 42%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Powertime holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Olarm has 32 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 42% of Powertime's written reviews are positive against 54% of Olarm's, so the app with the better star average is not the one people write more warmly about.

Powertime ships an update every 3 months, Olarm every 3 weeks. The most recent releases landed on October 15, 2026 and October 12, 2026 respectively.
