Verdict
The clearest difference is review sentiment: Feynman AI at 75% against Notelyn's 0%. Notelyn's advantage is rating (5.0 vs 4.4) and ads (none vs shown). On price, ratings volume, in-app purchases and monetization model 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. Feynman AI sells 5 in-app purchases, starting at $4.99 per 7 days and Notelyn sells 8 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Notelyn holds the better App Store score, 5.0 against 4.4. Both are backed by a comparable volume of ratings — 15 and 7 respectively. Written reviews complicate that: 75% of Feynman AI's written reviews are positive against 0% of Notelyn's, so the app with the better star average is not the one people write more warmly about.
Feynman AI ships an update monthly, Notelyn fortnightly. The most recent releases landed on October 24, 2026 and October 2, 2026 respectively.
