Add access to Evernote and MeasureMap apps to my app.

I have a program that is to be used in the agricultural advisory industry that will allow them to report to farmers that they visit on what they are thinking will be needed for a paddock. We have a very basic mapping attached - and note taking but i would like to add both MeasureMap and Evernote to the app as it will add greater versatility to my application. My application is based on Chrome and i need some help here.
