# REsimpli vs REI BlackBook

The clearest difference is rating: REsimpli at 4.9 against REI BlackBook's 3.7. REsimpli also leads on ratings volume (387 vs 3). REI BlackBook's advantage is in-app purchases (none vs 5) and iOS requirement (13.4 vs 18.4). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. REsimpli sells 5 one-off in-app purchases. REI BlackBook asks for nothing beyond the download.

REsimpli holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: REsimpli has 387 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 99% of REsimpli's written reviews are positive against 100% of REI BlackBook's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 25, 2026 and September 9, 2026 respectively.
