# SciAstra vs Bio Guru

The clearest difference is rating: Bio Guru at 5.0 against SciAstra's 3.5. Bio Guru also leads on update cadence (weekly vs every 9 months). SciAstra's advantage is review sentiment (80% vs 62%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Bio Guru holds the better App Store score, 5.0 against 3.5. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews complicate that: 80% of SciAstra's written reviews are positive against 62% of Bio Guru's, so the app with the better star average is not the one people write more warmly about.

SciAstra ships an update every 9 months, Bio Guru weekly. The most recent releases landed on October 5, 2026 and October 8, 2026 respectively.
