# Protocol vs Paradigm

The clearest difference is rating: Paradigm at 4.7 against Protocol's 4.2. Paradigm also leads on update cadence (every 3 weeks vs every 3 months) and ratings volume (268 vs 53). Protocol's advantage is in-app purchases (none vs 11) and iOS requirement (9.0 vs 15.0). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Paradigm sells 11 one-off in-app purchases. Protocol asks for nothing beyond the download.

Paradigm holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Paradigm has 268 ratings behind it against 53, so its average is the more settled of the two. Written reviews point the same way: 79% of Protocol's written reviews are positive against 81% of Paradigm's.
