# Keymagine vs Protokol

The clearest difference is ads: Keymagine at none against Protokol's shown. Keymagine also leads on rating (4.8 vs 4.5) and ratings volume (170 vs 16). Protokol's advantage is review sentiment (80% vs 55%) and update cadence (every 4 days vs every 2 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Keymagine sells 7 in-app purchases, starting at $4.99 per 7 days and Protokol sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Keymagine holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Keymagine has 170 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 55% of Keymagine's written reviews are positive against 80% of Protokol's, so the app with the better star average is not the one people write more warmly about.

Keymagine ships an update every 2 weeks, Protokol every 4 days. The most recent releases landed on October 17, 2026 and October 20, 2026 respectively.
