### 5/5 — Very nice App

*2026-02-03, version 3.5.4*

just installed it 10 minutes ago because I need something for a JBD bms that has not yet arrived. 

Just quickly tested it with my OverKill and xiaoxiang bms’s and it works great. Really like the multi device screen and the option to specify series or parallel. 

Well done!

Will update my review after the next bms shows up.

### 4/5 — Gute App mit Demenz

*2025-09-05*

Kann alles was das Herz begehrt (und mehr). Nur eine Sache ist extrem nervig:
Die App vergisst, welche Batterien man überwachen möchte.
Wenn man zwei Akkus hat, muss man nach jedem Start a) den Modus umschalten sowie b) und c) beide Akkus wieder neu auswählen.

Noch etwas: kann es sein, dass die Schalter für "charging" und "discharging" vertauscht sind?

### 1/5 — Funktioniert nicht

*2025-07-14*

I can connect to my four Ultramax SLAUMXLI100-12 (12.8V/100Ah) LiFePO4 battery but it only shows ZEROs everywhere. Also refund not possible!

### 5/5 — Great App

*2025-06-23, version 3.5.2*

I like this app because it finds batteries quickly and holds a stable connection to them.  You can also turn the charge or discharge of the battery on or off easily.

### 4/5 — Anzeige stimmt nicht mehr

*2025-03-25*

Seit dem letzten Update stimmt die Anzeige nicht mehr 
Es werden nur noch 50 % angezeigt obwohl die Batterie voll ist 
In der App 59 % und auf der Batterie 100 %
Habe jetzt festgestellt das es an den Einstellungen der Batterie liegt und nicht an der App
Also alles gut

**Developer response:** Hallo Merlin, das Problem liegt nicht an unserer App. Das BMS deiner Batterie muss neu kalibriert werden. Einer voller Lade- und Endladezyklus sorgt dafür das wieder alles passt. Bitte die Rezension dahingehend anpassen.

LG Justin

### 5/5 — Great bms app

*2024-08-07, version 3.4.0*

It was a good app to begin with but with the  latest update you can now receive notifications on cell delta. This was the only parameter missing that I really needed. Excellent developer that listens to feedback and added cell delta notifications upon suggestion, five stars.

### 5/5 — Awesome!

*2024-07-15*

The multi-mode is awesome. I have 3 DalyBMS and having a global view of the 3 batteries is really cool.

Some feature wishes:
- As the connection to the DalyBMS is quite unstable, I would like to have a cache for the latest values and just don't tell me the device is not responding or connection lost (as this is to be expected). Instead just give me a icon which tells me whether data comes from cache or live.
- I would like to be able to customize the values which are shown per battery in the global battery view.

### 5/5 — Sehr gut

*2024-04-06*

Endlich eine tolle App .
Hier sollte Bulltron mal in Kontakt treten.

Gruß

### 5/5 — Super APP - Spitzensupport

*2024-02-09*

Anfangs funktionierte die APP nicht mit meinen LifePo4 Batterien (SolarV)
Support kontaktiert und es wurde sehr schnell reagiert und angepasst.
Jetzt funktioniert alles einwandfrei
Tolle APP und Megasupport

### 5/5 — Best BMS app out there

*2023-08-15, version 3.0.0*

This is the cleanest most comprehensive bms app available and I am so glad I got it. Everything else has a terrible user interface and unintuitive logging. This app solves that for me.
