Does anyone use isis?

Does anyone use the isis app for android or apple? I heard if you sign up you can get a free $50, so i wanted to try it but i didn't know how it was. Also do you have to link a credit card with it or be a certain age? Finally can you use it at amazon? Thanks so much for the help.

I have never heard of it, but getting $50 for "free" when installing an app sounds tricky. I never trust those "marketing" sayings.
