Verdict
The clearest difference is rating: Physics Galaxy at 5.0 against SciAstra's 3.5. Physics Galaxy also leads on update cadence (every 2 months vs every 9 months). SciAstra's advantage is monetization model (free vs free with in-app purchases) and review sentiment (80% vs 67%). 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.
Physics Galaxy holds the better App Store score, 5.0 against 3.5. Both are backed by a comparable volume of ratings — 2 and 2 respectively. Written reviews complicate that: 67% of Physics Galaxy's written reviews are positive against 80% of SciAstra's, so the app with the better star average is not the one people write more warmly about.
Physics Galaxy ships an update every 2 months, SciAstra every 9 months. The most recent releases landed on June 5, 2026 and September 4, 2026 respectively.
