# Nano SigmaPlus vs Tuned Hearing

The clearest difference is rating: Nano SigmaPlus at 4.0 against Tuned Hearing's 2.8. Nano SigmaPlus also leads on ratings volume (81 vs 4) and iOS requirement (9.0 vs 14.0). Tuned Hearing's advantage is update cadence (every 2 months vs every 7 months) and review sentiment (100% vs 85%). 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.

Nano SigmaPlus holds the better App Store score, 4.0 against 2.8. That said, the two scores are not equally well evidenced: Nano SigmaPlus has 81 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 85% of Nano SigmaPlus's written reviews are positive against 100% of Tuned Hearing's, so the app with the better star average is not the one people write more warmly about.

Nano SigmaPlus ships an update every 7 months, Tuned Hearing every 2 months. Both last shipped on October 24, 2026.
