# X Factor vs Meltum

The clearest difference is in-app purchases: X Factor at none against Meltum's 1. X Factor also leads on rating (5.0 vs 4.8) and update cadence (weekly vs fortnightly). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Meltum sells 1 one-off in-app purchase. X Factor asks for nothing beyond the download.

X Factor holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 4 and 8 respectively. Written reviews complicate that: 60% of X Factor's written reviews are positive against 67% of Meltum's, so the app with the better star average is not the one people write more warmly about.

X Factor ships an update weekly, Meltum fortnightly. The most recent releases landed on September 30, 2026 and October 1, 2026 respectively.
