Exacto

Seems that WIX can't handle the traffic... ;)

Site doesn't seem to work - direct link to the app on iTunes - $2.99: https://itunes.apple.com/US/app/...

What makes this more powerful than FaceTune 2, Juxtaposition, Pixelmator, or several others that have had background removal/swap for some time? The pen can be precise, but the zoom/swipe/edge detection in many apps can get very exact results too. Not complaining, just curious!

Interface/UI color scheme feels eerily similar to UnionApp (another popular masking app) Tried this app out though and was really underwhelmed. Will be sticking with Union and their magic wand tool.

Android version?

As what others have said there are alternatives out there, for example, Pixc https://pixc.com/

are you planning to launch for Play Store?
