Can’t unsubscribe – Filterloop: Photo Editor Review

I’m possibly an idiot and can’t find where you can stop paying for the app. But I tried every button in the settings menu, and tried to email them for feed back but the feed back option won’t let me send the message. Cool app but when I end up paying more because the app won’t let me unsubscribe, makes me upset.
