Verdict

The call

The clearest difference is review sentiment: Tistu at 100% against Memhack's 41%. Tistu also leads on update cadence (every 3 days vs monthly). Memhack's advantage is rating (5.0 vs 4.5) and ratings volume (10 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Memhack holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Memhack has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 41% of Memhack's written reviews are positive against 100% of Tistu's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Memhack ships an update monthly, Tistu every 3 days. Both last shipped on November 7, 2026.
