Verdict
The clearest difference is rating: MasteryAI at 5.0 against Feynman AI's 4.6. MasteryAI also leads on iOS requirement (14.0 vs 18.6). Feynman AI's advantage is ratings volume (50 vs 2) and update cadence (every 6 days vs every 2 weeks). On price, ads, 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 7 in-app purchases, starting at $2.99 per 7 days and MasteryAI sells 3 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.
MasteryAI holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Feynman AI has 50 ratings behind it against 2, so its average is the more settled of the two.
Feynman AI ships an update every 6 days, MasteryAI every 2 weeks. The most recent releases landed on September 29, 2026 and September 23, 2026 respectively.
