I have tried the app and I’m a bit disappointed. The updates for one take ages to come through if they do at all. I sent test messages on Whatsapp to the target phone and this didn’t show up for hours. When I contacted their customer support they gave me instructions with a “secret” text message to refresh the app on the phone. This “secret ” message is not supposed to be visible on the target phone. Mine were all visible…more than 8 messages with the code. After a while-8 hours the messages just disappeared from the target phone(so good for stealth). They say that the phone has to be connected to WiFi…I am sure that the target phone is connected to WiFi. I think it’s a rip off
