Verdict
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.
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. Scratch Disc sells 1 one-off in-app purchase and Hypertron sells 14 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
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.
Scratch Disc ships an update every 3 weeks, Hypertron monthly. The most recent releases landed on June 1, 2026 and September 28, 2026 respectively.
