# Mood Detector Face Test Prank vs Elf Studio®

The clearest difference is in-app purchases: Mood Detector Face Test Prank at none against Elf Studio®'s 11. Mood Detector Face Test Prank also leads on review sentiment (56% vs 45%) and iOS requirement (9.0 vs 17.0). Elf Studio®'s advantage is update cadence (every 3 days vs every 3 months) and rating (4.7 vs 4.4). On price, ads and device support there is nothing between them.

Both are free to download. Elf Studio® sells 11 in-app purchases, starting at $1.99 per month. Mood Detector Face Test Prank asks for nothing beyond the download.

Elf Studio® holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Elf Studio® has 3.8K ratings behind it against 96, so its average is the more settled of the two. Written reviews complicate that: 56% of Mood Detector Face Test Prank's written reviews are positive against 45% of Elf Studio®'s, so the app with the better star average is not the one people write more warmly about.

Mood Detector Face Test Prank ships an update every 3 months, Elf Studio® every 3 days. The most recent releases landed on October 4, 2026 and October 18, 2026 respectively.
