@hitesh Thanks for your feedback.
AppyBuilder does have much expenses and we are all using our personal time to provide the service. All contributions / subscription (even at lower rate) are appreciated: http://appybuilder.com/appybuildersupport.html
Also, AppyBuilder displays ads to potentially generate few for cups-of-coffee. The ads are targeted based on user searches. Maybe you can all find some ads that are useful and interest you
