Verdict
The clearest difference is in-app purchases: Protocol at none against Project's 18. Protocol also leads on ads (none vs shown) and iOS requirement (9.0 vs 12.0). Project's advantage is rating (4.6 vs 4.2) and update cadence (monthly vs every 3 months). On price, review sentiment and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Project sells 18 one-off in-app purchases. Protocol asks for nothing beyond the download.
Project holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Project has 1.5K ratings behind it against 53, so its average is the more settled of the two. Written reviews complicate that: 72% of Project's written reviews are positive against 79% of Protocol's, so the app with the better star average is not the one people write more warmly about.
Project ships an update monthly, Protocol every 3 months. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
