# Level vs Spacetime Clock

The clearest difference is rating: Level at 4.4 against Spacetime Clock's 2.8. Level also leads on review sentiment (80% vs 41%) and monetization model (free vs paid). Spacetime Clock's advantage is update cadence (every 2 months vs every 6 months). On price, ads, in-app purchases and device support there is nothing between them.

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

Level holds the better App Store score, 4.4 against 2.8. That said, the two scores are not equally well evidenced: Level has 40 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 80% of Level's written reviews are positive against 41% of Spacetime Clock's.

Level ships an update every 6 months, Spacetime Clock every 2 months. The most recent releases landed on October 17, 2026 and October 14, 2026 respectively.
