Appify Custom Product Designer

Having a great experience with these guys. The app has so many options which makes it flexible, but also there is a bit of a learning curve because of the many options. I'm using it for stickers and it's a new app in this space, so there's currently a few snags, but their support has been super responsive (replied within the hour and bugs fixed within the same day), receptive to request and suggestions, and very proactive with fixing my configuration issues. This is a new product line for me and needed to find an app like this to enable my store to move beyond the "dev" phase and digitise the whole print / approve / purchase workflow.
