# Nix Solo vs Alleviate Therapy

The clearest difference is rating: Nix Solo at 4.8 against Alleviate Therapy's 3.4. Nix Solo also leads on update cadence (every 10 days vs monthly) and monetization model (free vs ad-supported). Alleviate Therapy's advantage is review sentiment (27% vs 14%). On price, ads, in-app purchases and device support there is nothing between them.

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

Nix Solo holds the better App Store score, 4.8 against 3.4. That said, the two scores are not equally well evidenced: Nix Solo has 69 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 14% of Nix Solo's written reviews are positive against 27% of Alleviate Therapy's, so the app with the better star average is not the one people write more warmly about.

Nix Solo ships an update every 10 days, Alleviate Therapy monthly. Both last shipped on November 7, 2026.
