# BuffMeter vs ProteinLog

The clearest difference is rating: ProteinLog at 5.0 against BuffMeter's 4.4. BuffMeter's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (7 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. BuffMeter sells 3 in-app purchases, starting at $2.99 per 7 days and ProteinLog sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ProteinLog holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: BuffMeter has 7 ratings behind it against 1, so its average is the more settled of the two.

BuffMeter ships an update every 4 days, ProteinLog weekly. The most recent releases landed on September 24, 2026 and September 20, 2026 respectively.
