# Octane X vs Axiom Solver

The clearest difference is review sentiment: Octane X at 51% against Axiom Solver's 0%. Octane X also leads on ratings volume (31 vs 5). Axiom Solver's advantage is rating (4.6 vs 3.7) and iOS requirement (16.4 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Axiom Solver holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Octane X has 31 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 51% of Octane X's written reviews are positive against 0% of Axiom Solver's, so the app with the better star average is not the one people write more warmly about.
