Love this app but a little confusing on pricing and logos

So I love this app!! I mean absolutely love it! I used it often and you get 8 free cut outs everyday before you can pay per photo or choose a subscription option.
So I had chose a monthly subscription and when I would get billed it was for $5 more than what it was supposed to be. But the logo shown was different then the logo on my phone or in my subscription list in the settings of my iPhone abs Apple ID. Do I couldn’t figure out where it was coming from or what it was that I was paying $9.99 a month for so I contacted apple and was refunded. Obviously that canceled my subscription and I figured all of this out. Since then they have added a lifetime subscription which I immediately took advantage of.
I’m still learning how to use all the features this app has to offer but what I love most is the cutouts it pretty much does all the work for you and is do accurate it’s almost unbelievable

Great for content creAters

This is great for content creators that are uploading big files and can’t wait because they have jobs to go to and they upload a video so as for me I have to wait until my video is completely uploaded for me to make my thumbnail because the app that I use is associated with the website that I’m uploading my video so until my videos completely uploaded I can’t make my thumbnails well with this I can make my son now and I already have it ready to go and attach it to the file so as soon as my videos done all I have to do is let it go public and this way I don’t have to wait or waste another day because I get home late night he could go out that same dayAnd at the fraction of the cost of other expensive cropping and editing some now creators this does a lot more and is way better

Actually Worth It.

I have never made a positive review before, I figure let people decide that for themselves, but when a developer/dev team shell out amazing update after update, eventually something has to give, and the last straw for me was the AI painting function added about 4 hours ago by the time this is written. I bought the life for png converting, and realized this app had so much more to offer, and is only getting better, seriously one of my greatest content-creating investments by far. You don’t have to put up money to see how good it is, so try it for yourself if your trying to get into that hobby.
