This is a great alternative to having an app built from scratch and investing multiple 5 figures.
They got me up and running quickly and were very receptive to any changes that I wanted made (short of adding specialty one-off custom features that required significant development).
I've been working primarily with Alyssa who's customer service is exemplary. She's responsive, detail-oriented, and is good at strategizing solutions to make the app function best for my clients.
Highly recommended!
