About the review mentioning the subscription problem, you have to go to your Apple ID and actually manage your subscriptions. Its a bit of a hassle but its possible.
I think the app is very intuitive and well made! It just needs a bit more people and Im sure with these reviews itll build that. I will say, however, Ive not run into any spam so far. Did run into one person who I think was trying to scam me though so I think this app could benefit from a "this is spam" deal perhaps.
