Verdict
The clearest difference is price: Bio at Free against 识图取字pro's $2.99. Bio also leads on update cadence (every 2 weeks vs every 3 months) and rating (5.0 vs 4.7). 识图取字pro's advantage is in-app purchases (none vs 3) and ratings volume (13 vs 2). On ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Bio is free to download; 识图取字pro costs $2.99 up front. Bio sells 3 in-app purchases, starting at $2.99 per month. 识图取字pro asks for nothing beyond the download.
Bio holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 识图取字pro has 13 ratings behind it against 2, so its average is the more settled of the two.
识图取字pro ships an update every 3 months, Bio every 2 weeks. The most recent releases landed on September 23, 2026 and September 30, 2026 respectively.
