# IDOLCHAMP vs Cosmo

The clearest difference is rating: Cosmo at 3.8 against IDOLCHAMP's 3.3. Cosmo also leads on ads (none vs shown). IDOLCHAMP's advantage is ratings volume (904 vs 281). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. IDOLCHAMP sells 12 in-app purchases, starting at $8.49 per month and Cosmo sells 14 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Cosmo holds the better App Store score, 3.8 against 3.3. Both are backed by a comparable volume of ratings — 904 and 281 respectively. Written reviews complicate that: 65% of IDOLCHAMP's written reviews are positive against 58% of Cosmo's, so the app with the better star average is not the one people write more warmly about.

IDOLCHAMP ships an update every 2 weeks, Cosmo every 8 days. Both last shipped on September 22, 2026.
