### 2/5 — Pig slow

*2025-12-26*

The app offers limited utility and does that poorly. It takes forever simply to load a few data points from each battery.

### 1/5 — No longer works!!!!!

*2025-08-26*

App doesn’t open and just gets stuck. PLEASE FIX!!! These batteries were too expensive for this to be acceptable.

### 1/5 — Not working

*2025-06-09*

App is not finding the batteries

### 1/5 — Doesn’t work

*2025-05-22*

App no longer works. Bug reports are closed. It gets stuck in a distorted version of the loading screen, and you never have the option to even try to connect to your batteries.
Significantly decreases the value of the batteries I got as the Bluetooth was a major selling point.
