Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.
