User reviews

Nur mit iPhone nicht mit Webcams möglich. Achtung versteckte Kosten !

Die App ist nur mit iPhones und nicht mit integrierten Webcams nutzbar. Das runterladen ist kostenlos, aber sobald am auf Einstellungen klickt soll sofort ein Abo abgeschlossen werden. Fenster und App lassen sich danach auch nur über Systemsteuerung wieder Schließen. Keine mitgelieferte Deinstallation Option.

DO NOT GET

App is horrid unless you wanna pay insane prices just to hit record. To to mention after 2 minutes of opening the app it throws a paywall at you and doesn’t let you close the app until you pay, or force quit. Extremely shady, and doesn’t even do anything special. Do not get

Not the OBS you think you are getting

Wasted money just to find out this application cannot record with multiple cameras at once. Do not waste your money. It only records from your phone, no pub in cameras.

Not working on obs

Obsessed won’t read it after paying 100 use for the subscription because it says OBS 4K
