Most useless app so far. Doesn't explain anything. it asks for a subscription after a few days. Also they place the delete account button at the bottom where you are unable to click it.

Hi Goran, I’m sorry your first experience with Vert was so frustrating. We’ve kept working on the app and recently released a major update. I hope you’ll give it another try and tell us how it feels this time. Thanks for being honest with us.
