# IDOLCHAMP vs 올차트[ALLCHART]

The clearest difference is review sentiment: IDOLCHAMP at 65% against 올차트[ALLCHART]'s 3%. IDOLCHAMP also leads on rating (3.3 vs 1.1) and ratings volume (904 vs 29). 올차트[ALLCHART]'s advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. IDOLCHAMP sells 12 in-app purchases, starting at $8.49 per month and 올차트[ALLCHART] sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

IDOLCHAMP holds the better App Store score, 3.3 against 1.1. That said, the two scores are not equally well evidenced: IDOLCHAMP has 904 ratings behind it against 29, so its average is the more settled of the two. Written reviews point the same way: 65% of IDOLCHAMP's written reviews are positive against 3% of 올차트[ALLCHART]'s.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
