Verdict

The call

The clearest difference is rating: Hypertron at 4.4 against Scratch Disc's 3.3. Hypertron also leads on ratings volume (159 vs 16). Scratch Disc's advantage is review sentiment (68% vs 53%) and iOS requirement (7.1 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Hypertron holds the better App Store score, 4.4 against 3.3. That said, the two scores are not equally well evidenced: Hypertron has 159 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 68% of Scratch Disc's written reviews are positive against 53% of Hypertron's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Scratch Disc ships an update every 3 weeks, Hypertron monthly. The most recent releases landed on June 1, 2026 and September 28, 2026 respectively.
