Verdict
The clearest difference is in-app purchases: Einstein™ Brain Training HD at none against Hitori Pro's 10. Einstein™ Brain Training HD also leads on rating (4.4 vs 4.0) and ratings volume (48 vs 5). Hitori Pro's advantage is review sentiment (100% vs 81%) and price ($0.99 vs $2.99). On update cadence, ads, monetization model and chart position 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
Einstein™ Brain Training HD costs $2.99 and Hitori Pro $0.99 up front. Hitori Pro sells 10 one-off in-app purchases. Einstein™ Brain Training HD asks for nothing beyond the download.
Einstein™ Brain Training HD holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Einstein™ Brain Training HD has 48 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 81% of Einstein™ Brain Training HD's written reviews are positive against 100% of Hitori Pro's, so the app with the better star average is not the one people write more warmly about.
Einstein™ Brain Training HD ships an update every 2 months, Hitori Pro monthly. The most recent releases landed on September 27, 2026 and September 10, 2026 respectively.
