I reviewed Appy Pie (at their request) after purchasing a reseller account. At that point the customer service was great and the actual product seemed to be exactly what I was after.
When I began using the platform, I learned very quickly that what they claim to offer is not what you get. The features/plugins break regularly and many of them do not actually work. The app template designs are fixed and far from graceful from a design and functionality perspective.
When I called in for support for these issues, I was met with a completely different customer service experience. The reps were not helpful, they were argumentative and when I attempted to cancel the service asked for a refund for the $1200 I had paid, they refused.
I then spent more than two months trying to get help building the three apps that I had bought the service for, with no success. Meanwhile the clients that I was building the apps for were bangin on my door as the project was well over deadline.
To make an incredibly long story short, I threw in the towel and played cleanup to salvage the client relationship. Out $1200 and months of my time, I felt I should update my this review site with my experience.
