# OOG vs Protokol

The clearest difference is in-app purchases: OOG at none against Protokol's 6. OOG also leads on ads (none vs shown) and chart position (#202 vs unranked). Protokol's advantage is update cadence (every 4 days vs every 2 weeks) and iOS requirement (15.1 vs 17.0). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. Protokol sells 6 in-app purchases, starting at $4.99 per month. OOG asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for OOG against 4.5 for Protokol. Both are backed by a comparable volume of ratings — 62 and 17 respectively. Written reviews are what separate them: 84% of OOG's written reviews are positive against 80% of Protokol's.
