# Bio vs Mirror Personality + Astrology

The clearest difference is rating: Mirror Personality + Astrology at 4.7 against Bio's 4.0. Mirror Personality + Astrology also leads on update cadence (every 2 weeks vs every 6 months) and ratings volume (1.1K vs 1). Bio's advantage is review sentiment (100% vs 65%) and monetization model (free vs freemium). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Bio sells 3 one-off in-app purchases and Mirror Personality + Astrology sells 9 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Mirror Personality + Astrology holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Mirror Personality + Astrology has 1.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Bio's written reviews are positive against 65% of Mirror Personality + Astrology's, so the app with the better star average is not the one people write more warmly about.

Bio ships an update every 6 months, Mirror Personality + Astrology every 2 weeks. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
