### 1/5 — No Updates, Not Accurate

*2025-07-04, version 1.2*

When discharging the % jumps from 60% to 0% within seconds. Not very reliable. Hasn't been updated for years!

### 1/5 — Please improve this App

*2023-07-24, version 1.2*

Let it at least show the remaining Ah of the battery and if it is charging or decharging.

### 4/5 — Passwords

*2022-11-04, version 1.2*

I found that passwords:

1234 - allows you to change bt battery display name
5678 - shows each cell voltage 

Possibly there’s more codes to enable advanced functions. Will update the comment if I find anything else.

### 4/5 — Password

*2022-02-17, version 1.2*

App works well, but what is the Password for settings ?   Thanks
