Verdict
The clearest difference is rating: SimDif at 4.7 against Crayon's 3.0. SimDif also leads on ratings volume (1.6K vs 4) and review sentiment (81% vs 61%). On price, ads, in-app purchases and monetization model 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. SimDif sells 15 in-app purchases, starting at $3.99 per month and Crayon sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
SimDif holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: SimDif has 1.6K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 81% of SimDif's written reviews are positive against 61% of Crayon's.
SimDif ships an update monthly, Crayon every 3 months. Both last shipped on September 22, 2026.
