# S vs AUXSOL

The clearest difference is rating: AUXSOL at 5.0 against S's 4.3. AUXSOL also leads on update cadence (fortnightly vs monthly). S's advantage is ratings volume (15 vs 2). 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.

AUXSOL holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: S has 15 ratings behind it against 2, so its average is the more settled of the two.

S ships an update monthly, AUXSOL fortnightly. Both last shipped on November 3, 2026.
