Note: If you don’t want to deal with stuff like this, I recommend you download and use it from F-Droid client or Accrescent AppStore.
Update: The app returned to the App Store.
Maybe it was a mix up? I just checked their website and clicked on the link they had for playstore and then downloaded it from there.
I just checked again and I can confirm the same.
I will edit the post to reflect this.
