The clearest difference is rating: Rudoku at 4.7 against fiilX's 1.0. Rudoku also leads on update cadence (every 3 weeks vs every 2 months) and ratings volume (19 vs 1). fiilX's advantage is review sentiment (100% vs 85%) and iOS requirement (12.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Rudoku holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Rudoku has 19 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of fiilX's written reviews are positive against 85% of Rudoku's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

fiilX ships an update every 2 months, Rudoku every 3 weeks. The most recent releases landed on October 2, 2026 and October 16, 2026 respectively.
