# Ruler Estimation vs PermitTrace

The clearest difference is update cadence: PermitTrace at every 3 days against Ruler Estimation's fortnightly. Ruler Estimation's advantage is ratings volume (17 vs 3) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Ruler Estimation sells 7 in-app purchases, starting at $49.99 per month and PermitTrace sells 2 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Ruler Estimation against 5.0 for PermitTrace. That said, the two scores are not equally well evidenced: Ruler Estimation has 17 ratings behind it against 3, so its average is the more settled of the two.
