For now, the app is okay. It's not exactly what I wanted, but it's okay. But the constant harassment by the developer asking me to change my review is a huge turnoff. Emails, text messages, voice mails. I'm expecting them to show up at my house any minute. Creepy and rude.
Updates: We are sorry to disturb you, but we try to do our best to provide our customers with the best support. So if we've got the review that is not relevant to our app, we try to find out the reason of that.
Please, note, we don't have any yearly or premium plan.
We don't associate with Etsy and we don't develop the app on their behalf.
