# Reverse Flow vs Rope Access Logbook

Reverse Flow and Rope Access Logbook are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Reverse Flow sells 4 in-app purchases, starting at $2.99 per month and Rope Access Logbook sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
