# Diode Dynamics vs OPTIMA Lithium Bluetooth

The clearest difference is rating: OPTIMA Lithium Bluetooth at 3.7 against Diode Dynamics's 2.9. OPTIMA Lithium Bluetooth also leads on update cadence (every 3 months vs every 34 months). Diode Dynamics's advantage is review sentiment (26% vs 0%) and ratings volume (56 vs 3). 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.

OPTIMA Lithium Bluetooth holds the better App Store score, 3.7 against 2.9. That said, the two scores are not equally well evidenced: Diode Dynamics has 56 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 26% of Diode Dynamics's written reviews are positive against 0% of OPTIMA Lithium Bluetooth's, so the app with the better star average is not the one people write more warmly about.

Diode Dynamics ships an update every 34 months, OPTIMA Lithium Bluetooth every 3 months. The most recent releases landed on September 22, 2026 and June 1, 2026 respectively.
