Verdict

The call

The clearest difference is ads: Skull Up at none against Fantamon's shown. Skull Up also leads on rating (4.7 vs 4.4). Fantamon's advantage is review sentiment (58% vs 42%) and chart position (#54 vs unranked). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Fantamon sells 10 one-off in-app purchases and Skull Up sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Skull Up holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 713 and 1.8K respectively. Written reviews complicate that: 58% of Fantamon's written reviews are positive against 42% of Skull Up's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Fantamon ships an update every 2 weeks, Skull Up every 10 days. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
