### 1/5 — Doesn’t work

*2026-06-25, version 2.3.0*

This just doesn’t work on my 2017 leaf. Simply won’t connect to it. I’ve seen online it’s supposed to be great. But it didn’t work my for 2017 leaf and the UI is so clunky it’d be really hard to work even it it did connect to the car.

### 1/5 — Решите проблему с Wi-Fi!

*2026-05-01*

До сих пор не решена проблема с подключением к Wi-Fi-адаптерам. Купите Айфон в компанию и протестируйте вживую. Раньше все работало, но «купила баба порося»… Пусть программеры всё вернут как было.

### 1/5 — Doesn’t work with WiFi

*2026-04-27, version 2.2.0*

Despite following the instructions carefully regarding selecting the dongle WiFi and setting for ip, the app doesn’t detect the WiFi ssid in use (fields are blank), so can’t set it in settings. Wasted £20. Pity I used to use the original free app which worked well.

### 3/5 — После обновления не видит адаптер!

*2026-04-27, version 2.2.0*

После обновления приложение перестало видеть вайфай адаптер, не подключается к автомобилю! Исправьте это пожалуйста, либо верните старую версию! Очень жалею что обновился.

### 2/5 — Won’t connect to Nissan Leaf 2 2020 after update!

*2026-04-23, version 2.2.0*

Won’t connect to Nissan Leaf 2 2020 after update!
After the latest update, the app completely stopped connecting to my Nissan Leaf 2 2020. Car is fine, OBD adapter works with other apps, but here—nothing. Same issue for many Leaf owners of this model (checked forums). Roll back the update or fix the bug ASAP! Very disappointed…

### 1/5 — Wi-Fi

*2026-04-22*

最初は繋がったが繋がらなくなった

SSIDが見つからないのはなぜ？

### 1/5 — Update

*2026-04-14*

After the update, the app doesn’t get wifi connection anymore. Please fix asap

### 5/5 — Great app!

*2026-04-12*

I used this app extensively on my 2023 Leaf and loved it! Now I have a 2026 Leaf and would happily pay extra for this app to support it. 2026 Leaf is an entirely different generation from the previous ones and not currently supported.

### 5/5 — Please support ZE2!

*2026-04-11*

ZE2 pls.

### 1/5 — Does not connect using Stahlcar 350 connector

*2026-04-03, version 2.0.0*

This app was a waste of money because it did not connect with the Stahlcar connector which it said it would. I ate of money and TIME.
