Verdict

The call

The clearest difference is rating: Linearity Curve Graphic Design at 4.5 against Roughups's 3.0. Linearity Curve Graphic Design also leads on ratings volume (14K vs 2) and device support (3 vs 1). Roughups's advantage is review sentiment (100% vs 61%) and update cadence (every 2 days vs every 9 days). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Linearity Curve Graphic Design sells 15 in-app purchases, starting at $7.99 per 7 days and Roughups sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Linearity Curve Graphic Design holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Linearity Curve Graphic Design has 14K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 61% of Linearity Curve Graphic Design's written reviews are positive against 100% of Roughups's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Linearity Curve Graphic Design ships an update every 9 days, Roughups every 2 days. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
