### 1/5 — Doesn’t work

*2025-01-13, version 1.1*

Doesn’t see the Bluetooth from the battery monitor. Pointless buying the HardKorr battery monitor if wanting Bluetooth. Better to invest in quality product rather than this rubbish.

### 1/5 — Connectivity

*2025-01-03, version 1.1*

Wont connect
cant reaet anything
bit of a dud really

### 3/5 — Updated app now no connection

*2024-03-31, version 1.1*

Had trouble with connecting on previous version so saw the update … silly me

### 1/5 — Bluetooth connection issues

*2024-03-03, version 1.1*

Bluetooth worked fine for the first week, now app just won’t pickup the device despite my phone being right next to it

### 5/5 — Awesome

*2024-01-14, version 1.0*

Great app

### 1/5 — Update

*2023-02-10, version 1.0*

Please can you please update it. It is not accurate to what the monitor says.

### 1/5 — App needs to be updated

*2022-10-07, version 1.0*

This app needs to be updated to maintain user friendly screen but with more relevant data.

Renogy Bluetooth app is a good standard to work from.
