# OSIRO オシロ vs mixi2

The clearest difference is review sentiment: mixi2 at 79% against OSIRO オシロ's 10%. mixi2 also leads on ratings volume (23 vs 1). OSIRO オシロ's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.

OSIRO オシロ holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: mixi2 has 23 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 10% of OSIRO オシロ's written reviews are positive against 79% of mixi2's, so the app with the better star average is not the one people write more warmly about.

OSIRO オシロ ships an update fortnightly, mixi2 every 8 days. The most recent releases landed on October 10, 2026 and October 12, 2026 respectively.
