# Astro Gold Astrology vs Bio

The clearest difference is review sentiment: Bio at 100% against Astro Gold Astrology's 52%. Bio also leads on monetization model (free vs free with in-app purchases) and rating (4.0 vs 3.7). Astro Gold Astrology's advantage is update cadence (monthly vs every 6 months) and ratings volume (234 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Astro Gold Astrology sells 10 in-app purchases, starting at $7.99 per month and Bio sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Bio holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: Astro Gold Astrology has 234 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 52% of Astro Gold Astrology's written reviews are positive against 100% of Bio's.

Astro Gold Astrology ships an update monthly, Bio every 6 months. The most recent releases landed on November 10, 2026 and November 1, 2026 respectively.
