# Ruler AR vs ARuler

The clearest difference is rating: Ruler AR at 4.3 against ARuler's 1.0. Ruler AR also leads on ratings volume (3.5K vs 1). ARuler's advantage is ads (none vs shown) and monetization model (free vs freemium). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Ruler AR sells 3 in-app purchases, starting at $1.99 per month and ARuler sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Ruler AR holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: Ruler AR has 3.5K ratings behind it against 1, so its average is the more settled of the two.
