Meh

No support

I was getting app support from Lee in the fall of 2025 and then he suddenly stopped responding to emails. I can only assume the app is no longer active. This is unfortunate as the app really seemed to be promising.

Great potential, no support

I really believed in the potential of this app. I was testing it and emailed support. Lee answered once and was very helpful but then I couldn’t get him to respond to the next three attempts to reach them. I’m left to believe the app is no longer supported.
