One Disappointed Premium Newbie

I wanted to see my stats and this app looked cool af. So I immediately bought the premium and… I lament my financial choices. This app hates iOS and its services with a burning passion. You use Apple Music? Too bad, our charts only favour Spotify users. Oh you wanna reopen the app after you closed accidentally? Well, sorry! Our app freezes and becomes unusable, even on a new iPhone. PLEASE FIX THE APP for iOS users too.
