### 5/5 — Чудова аплікація

*2026-01-20*

Чудова програма для Опель, але шкода, що немає української мови.

### 5/5 — Супер

*2025-10-12, version 1.2.51*

Все прекрасно работает на vgate fs. За такие программы хочется денег отнести.

### 1/5 — Müll!!

*2025-09-04*

Nur in Polnische Sprache.. Die App stürzt ständig ab und damit unbrauchbar. Kontaktaufnahme nicht möglich. Selbst, wenn man die kontaktiert, keinerlei Antworten weder über die App noch über die Webseite. Einfach nur unterirdisch…

### 5/5 — Отличное приложение

*2025-08-27, version 1.2.51*

Слежу за заполнение сажи на современном дизеле. Минус это цена платной версии 15 уе в год (но и без подписки программа со своей функцией справляется на все 100%)

### 1/5 — Nie dziala z ip

*2025-06-07, version 1.2.51*

Probowalem 2 zlaczy. Ip15 nie chce sie z zadnym polaczyc

### 1/5 — Would be great if has support

*2025-05-30, version 1.2.51*

Got this and paid for it but there is no support at all. You can’t pull make extra gauges and have all the stuff you want in one place…. Well that’s what it says!! You try to import any settings and it crashes. You try to add a panel with gauges you want and there are none in the list. I have emailed them about 8 times now with no response at all. 

I got a free app off the store and it’s way better than this. You can add what you want. 
Also with this if you want extra bits they are £39.99 each!!!

### 5/5 — Rozszerzanie licznika

*2025-04-08, version 1.2.51*

Za 250 zł można bez problemu, bezpiecznie i szybko rozszerzyć funkcje licznika w Oplu Insigni A 2016

### 5/5 — Aplikacja

*2025-04-06, version 1.2.51*

Aplikacja super tylko teraz na iPhonie nie chce mi działać 
Mogę liczyć na jakąś pomoc?

### 5/5 — Absolutely superb!

*2025-03-13, version 1.2.51*

If you drive a Vauxhall/Opel, this app is a must have. It gives clear and concise information on lots of key parameters of your car, including the all important DPF levels. 

As well as giving you information, the app is also a full blown diagnostics as well. It reads the codes on all the modules in the car, not just the check engine light like a lot of cheap readers so. Get this app!!!

### 5/5 — Super

*2024-12-15, version 1.2.51*

Właśnie skasowałem błąd Check Engine.
