Verdict
The clearest difference is price: Dized at Free against Formula D/De Roller's $0.99. Dized also leads on rating (4.6 vs 3.0) and update cadence (every 2 months vs every 43 months). Formula D/De Roller's advantage is in-app purchases (none vs 10) and review sentiment (50% vs 40%). On ads and device support there is nothing between them.

Dized is free to download; Formula D/De Roller costs $0.99 up front. Dized sells 10 in-app purchases, starting at $2.99 per month. Formula D/De Roller asks for nothing beyond the download.
Dized holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Dized has 328 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Formula D/De Roller's written reviews are positive against 40% of Dized's, so the app with the better star average is not the one people write more warmly about.
Formula D/De Roller ships an update every 43 months, Dized every 2 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
