# ARuler vs Bluetooth

The clearest difference is rating: Bluetooth at 3.9 against ARuler's 1.0. Bluetooth also leads on ratings volume (9 vs 1). ARuler's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (11.0 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ARuler sells 1 one-off in-app purchase and Bluetooth sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Bluetooth holds the better App Store score, 3.9 against 1.0. That said, the two scores are not equally well evidenced: Bluetooth has 9 ratings behind it against 1, so its average is the more settled of the two.

ARuler ships an update every 3 months, Bluetooth every 6 weeks. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
