# Device Kit vs Scrolla

The clearest difference is rating: Device Kit at 4.9 against Scrolla's 4.4. Device Kit also leads on ratings volume (95 vs 16). Scrolla's advantage is update cadence (every 3 days vs every 10 days) and review sentiment (87% vs 78%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Device Kit sells 4 in-app purchases, starting at $3.99 per month and Scrolla sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Device Kit holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Device Kit has 95 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 78% of Device Kit's written reviews are positive against 87% of Scrolla's, so the app with the better star average is not the one people write more warmly about.

Device Kit ships an update every 10 days, Scrolla every 3 days. Both last shipped on November 10, 2026.
