Verdict

The call

The clearest difference is review sentiment: HSK CERT at 96% against Math.Brain's 50%. HSK CERT also leads on ads (none vs shown). Math.Brain's advantage is rating (4.8 vs 4.2) and ratings volume (90 vs 17). On price, update cadence, 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

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Math.Brain sells 4 in-app purchases, starting at $12.99 per 7 days and HSK CERT sells 7 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Math.Brain holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Math.Brain has 90 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 50% of Math.Brain's written reviews are positive against 96% of HSK CERT's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Math.Brain ships an update every 8 days, HSK CERT fortnightly. The most recent releases landed on November 5, 2026 and November 8, 2026 respectively.
