Verdict
The clearest difference is rating: Hologo at 4.4 against Mental Math's 3.7. Hologo also leads on ratings volume (194 vs 19) and iOS requirement (13.0 vs 15.0). On price, review sentiment, update cadence and ads 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. Hologo sells 4 in-app purchases, starting at $9.99 per month and Mental Math sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Hologo holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: Hologo has 194 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 61% of Hologo's written reviews are positive against 63% of Mental Math's, so the app with the better star average is not the one people write more warmly about.
Hologo ships an update monthly, Mental Math every 5 weeks. The most recent releases landed on October 20, 2026 and October 21, 2026 respectively.
