## Most critical reviews (7 lowest-rated)

### 1/5 — Useless App

*2025-04-13, version 1.0.1*

Never been able to connect. Please update the app

### 1/5 — For the $$ spent you need to Sort it out

*2024-09-29, version 1.0.1*

Won’t connect. 
Absolutely useless.

### 1/5 — FIX THE APP IT DOESNT WORK

*2024-09-13, version 1.0.1*

Can’t see anything never connects useless

### 1/5 — About the same as having no info

*2024-06-09, version 1.0.1*

Doesn’t show much information and the history is close to useless. Worst power system app I’ve used. About to swap the Hardkorr DCDC charger with a Victron as their app and info is a million times better.

### 1/5 — Never connects

*2024-01-31, version 1.0.1*

Wont connect easy. Doesnt find in phone bluetooth settings to connect. Should just auto connect. Terrible

### 1/5 — App disconnecting to DC-DC

*2024-01-24, version 1.0.1*

App keeps disconnecting from dc dc and not getting readings. Pretty poor for something that should simply just give a reading.

### 2/5 — Very basic, requires regular force quit and restart

*2024-05-09, version 1.0.1*

I’ve been using this for about a year now and I’ve just come to terms that it is a good hardware app. The app is very very basic, it just shows values weird error messages with no context and Bluetooth disconnects and reconnecting doesn’t work unless you quit the app and restart.
