As the number of smartphone users continues to grow, sooner or later, it will be inevitable that businesses/services be made available as apps across platforms. But the cost of building an app doesn’t seem like a profitable proposition, particularly for small businesses or professionals. Even if you do design one yourself, there are factors that need to be considered, like buying cloud storage, hiring an engineer for technical support, etc. This is when a web service like Instappy.com comes handy. The Web service allows you to build your own app via its easy-to-use Web interface in just 60 minutes.
