# Smart Level vs Clinometer+

The clearest difference is rating: Clinometer+ at 4.5 against Smart Level's 3.5. Clinometer+ also leads on ratings volume (1K vs 2) and update cadence (every 2 months vs every 12 months). Smart Level's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (7.0 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Smart Level sells 1 one-off in-app purchase and Clinometer+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Clinometer+ holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Clinometer+ has 1K ratings behind it against 2, so its average is the more settled of the two.

Smart Level ships an update every 12 months, Clinometer+ every 2 months. The most recent releases landed on October 10, 2026 and October 13, 2026 respectively.
