### 1/5 — Leider nicht zum Verbinden.

*2026-08-14*

Habe jetzt 3 OBD Adapter und mit einen lasst sich die App verbinden. Lieder gibt es auch keine Einstellungen so wie bei Android, dann könnte man auch eine Verbindung auswählen. 
Es gibt überhaupt keine Einstellungen. 
Das is leider sehr schade für so eine App.

### 5/5 — Как скачать lite версию

*2026-08-02*

Реализуйте какую-либо доступную возможность покупки lite-версии

### 1/5 — Нет соединения по Wi-Fi

*2026-07-11*

Исправьте пожалуйста приложение. Ранее соединялось норм. После последнего обновления вообще никак (ios 26.5.2)

### 5/5 — Affordable DIY Diagnostic that works

*2026-04-30*

I picked up FORScan Lite for my Mazda and it’s been really handy. For $6.99 it reads error codes, shows live data, and covers multiple modules like PCM and BCM. The dashboard and graph views make diagnostics clear even for non-pros. Setup with my OBD adapter was quick. It’s a solid, affordable tool that saves trips to the mechanic.

### 1/5 — Айфоны подключаются через wi fi

*2026-04-27*

Нет такой функции, не можем подключиться

### 1/5 — Не подключается

*2026-04-06*

Не подключается. На андройде к этому же адаптеру через форскан по блютуз подключается. Здесь по вай фай-нет. Все остальные программы работают

### 1/5 — Не видит ELM

*2026-03-20*

Если это реклама приложения - то плохая. Сделайте возможность выбирать устройство к которому нужно подключатся как это реализовано например в том же car scanner, oplmonitor. Попробовал подключить сканер - ваш автопоиск не видит устройство ELM327 (в списках устройств оно называется OBD II snowman) и оно работает с другими приложениями без проблем. А тут из-за отсутствия возможности выбрать куда подключаться толку от приложения ноль.

### 5/5 — So viele Daten

*2026-02-23*

Die App ist Mega gut man kann so viele Daten auslesen und Rückschlüsse schließen was mit dem Fahrzeug eventuell nicht stimmt. Man kann sogar Daten sehen, die das Auto weiß aber der sonst nicht mitteilt wie zum Beispiel Reifen Luftdruck, Zustand, AGR und so weiter

### 1/5 — Не работает

*2026-01-12*

Не находит сканер Vgate iCar Pro 2S и нет никаких ограничений настроек, чтоб выбрать тип подключения (wifi, bluetooth).

### 5/5 — Works Awesome!

*2025-11-01*

This is the app that all vehicle manufactures should supply with a new vehicle!
I love almost everything about FORScan. 
You can monitor almost all your Ford vehicle's sensors live, record their outputs, save their outputs to you iPhone or iPad and then export them into your laptop for analysis. 
You can view and reset your error codes. 
Plus you can program and change multiple setting on your vehicle for both performance and esthetics.
All around necessity for Ford owners!!!!
Thank you so much for all of you hard work in bringing this software to us!!!
