Pricing insights for Feynman AI: Note,Mindmap,Memo
Feynman AI: Note,Mindmap,Memo is an Education app for iOS, and it costs nothing to download in any tracked region. All real cost in this app sits inside in-app purchases, and that is the only place regional pricing appears.
The product worth watching is "Yearly - Unlimited." It is cheapest in the United States at USD 95.99 and most expensive in Ukraine at USD 119.99. That 20% price difference across 4 regions is the only real saving available in this price data. Because the app itself is free everywhere, there is no download price to compare and no cheaper market hiding a paid version.
What that means: check the price before you pay, not after. Buyers in the US already sit at the floor of the range. Buyers in Ukraine pay the top of it. This gap is steady regional pricing, not a temporary spike, so expect the same spread over the life of a purchase.
The app lists 12 distinct in-app purchase products, so "Yearly - Unlimited" is one line on a longer price list. Other in-app purchases exist inside the app, but only this one carries named regional figures in the verified data. The App Store listing does not flag subscriptions, so confirm what a purchase unlocks before assuming a recurring charge on your account.
Developer is Nguyen Thanh Duy. The app holds a 4.52 out of 5 rating from 257 reviews on iOS. Pricing was checked across 49 regions.
Bottom line: the app is free to get, and the cost that matters is the yearly unlimited in-app purchase, cheapest in the United States at USD 95.99 and most expensive in Ukraine at USD 119.99.
