Having previously used the Skycaddie devices for years this is the first one I can read very clearly from my iPhone on a sunny day. Using the iPhone 6s Plus the app appears huge and easy to see. Entering your scores is fast and easy.
I would recommend being able to easily place a pin in a custom position like on Skycaddie. Sometimes that narrows down which club I want to use as I approach the green.
Keep it simple in future updates.
