# GH vs Protokol

The clearest difference is ads: GH at none against Protokol's shown. Protokol's advantage is update cadence (every 4 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. GH sells 3 in-app purchases, starting at $3.99 per month 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.

GH ships an update every 2 months, Protokol every 4 days. The most recent releases landed on November 13, 2026 and November 5, 2026 respectively.
