Ever app hack?

Earlier today i got an invitation from a family member to look at photos on the Ever app. I clicked on the link. Downloaded the app from the app store, and created an account. When I realized they were going to upload my photos I clicked delete. And deleted the app.

what is the deal?

Anyone ever hear of this?

How can I tell if its been hacked?

 

I chatted with apple support online and they said its hard for people to use apps to actually hack your device. I got to the part where it allows you to toggle on and off what things you want the app to access. And when it listed all that stuff it got me nervous and I knew the app shouldn't have access to that stuff. I deleted the app, but I did create an account and when I go to the app in the app store now, I see a cloud. So its in the cloud now? Theres no way to fully delete it?

I guess its just a spam app. its legit. its a real app. But its spam. Some of the reviews say it takes your contacts and sends that message to other people asking them to download the app etc...

I didnt give the app permission to access anything even though I created an account so I hope everything is fine.

What do I look out for in terms of a hacked phone? What behaviors would it exhibit?
