I bought the Postmates Clone- iDeliver, (https://www.appscrip.com/postmates-clone-on-demand-delivery/) from these guys. These guys are customizing it currently to suit my business right now. I absolutely love these guys, they are always available whenever I need to communicate with them, very prompt.
They take initiatives to make the product better, and Rahul, CEO at Appscrip has been more than just tech partner, he jumps on calls with me every now then to check in and see if I am comfortable with his team's performance.
I would suggest Appscrip to all the people looking for a company to develop a mobile app for their business.
