3 years ago. I wasn’t happy with this app. Read my previous review

Now I just reinstalled again. Location access seems to have been fixed now. Love this app now.
Thanks for this safety app.

Leider nicht Aktuell

Ist leider bei der Version 1.90 stehen geblieben.
Ich habe es gekauft und kann nur die Grundversion nutzen. Nichts ist einstellbar und der Leistungsumfang, der versprochen wurde, wird nicht geliefert. Aussage des Supports, das würde am IOS 16 liegen, hat mir auch nicht geholfen. So für mich nicht nutzbar und rausgeschmissenes Geld.
