Listr: Wishlist + Reminder

THE WORST !!! Its been a week already since i asked for support to help me fix some things that are not working in the app , they answered the 1st day i sent a message and after that never again, i have sent 4 emails already as a reminder i am getting no reply at all.
i can say this is the worst customer experience ever & i would never recommend this to my worst enemy :)

Great support, fast friendly and effective!

Is there a way to contact the maker of this? I installed everything and the heart is not adding anything to the wish list when I click on it. I can find no phone number of help section in the app. Please help or I'll just uninstall. Thank you.

Promising , doesn't work on all sites ..
