# RAVEN2 vs Blue Protocol

The clearest difference is rating: Blue Protocol at 4.7 against RAVEN2's 3.2. Blue Protocol also leads on review sentiment (52% vs 29%) and ratings volume (4.7K vs 272). RAVEN2's advantage is update cadence (monthly vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. RAVEN2 sells 47 one-off in-app purchases and Blue Protocol sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Blue Protocol holds the better App Store score, 4.7 against 3.2. That said, the two scores are not equally well evidenced: Blue Protocol has 4.7K ratings behind it against 272, so its average is the more settled of the two. Written reviews point the same way: 29% of RAVEN2's written reviews are positive against 52% of Blue Protocol's.

RAVEN2 ships an update monthly, Blue Protocol every 2 months. Both last shipped on October 26, 2026.
