# WeightBuddy vs Protocol

WeightBuddy and Protocol both sit at 4.9 stars, but that hides the real split: 100% of Protocol's written reviews are positive against 70% of WeightBuddy's. Protocol also leads on update cadence (weekly vs fortnightly). WeightBuddy's advantage is ratings volume (376 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. WeightBuddy sells 11 in-app purchases, starting at $4.99 per month and Protocol sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for WeightBuddy against 5.0 for Protocol. That said, the two scores are not equally well evidenced: WeightBuddy has 376 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 70% of WeightBuddy's written reviews are positive against 100% of Protocol's.

WeightBuddy ships an update fortnightly, Protocol weekly. The most recent releases landed on October 25, 2026 and October 6, 2026 respectively.
