# GERDBuddy vs AcidLog

The clearest difference is rating: AcidLog at 5.0 against GERDBuddy's 4.5. GERDBuddy's advantage is ratings volume (31 vs 1) and update cadence (every 9 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. GERDBuddy sells 5 in-app purchases, starting at $6.99 per month and AcidLog sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

AcidLog holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: GERDBuddy has 31 ratings behind it against 1, so its average is the more settled of the two.

GERDBuddy ships an update every 9 days, AcidLog every 3 weeks. Both last shipped on October 25, 2026.
