Verdict
The clearest difference is review sentiment: SnapNotes at 100% against Keys's 38%. SnapNotes also leads on iOS requirement (15.0 vs 17.6). Keys's advantage is rating (4.5 vs 4.2) and ratings volume (182 vs 5). On price, update cadence, ads and in-app purchases 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. Keys sells 5 in-app purchases, starting at $6.99 per 7 days and SnapNotes sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Keys holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Keys has 182 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 38% of Keys's written reviews are positive against 100% of SnapNotes's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on November 9, 2026 and October 31, 2026 respectively.
