In a device-friendly world, we have all our gadgets tweaked to our needs. Whether it is a PC, phone or tablet, we customize it with what we want. We want to change backgrounds and install entertaining and useful apps. The app ecosystem has grown considerably in various mobile platforms. The development tools for the Windows Phone platform are good enough for creating mobile apps and standard compared to other development tools used for other mobile platforms.
Rule No. 1: Embrace Metro
For most smartphones including Windows Phone, all of them revolve around great and unique looks and some tweaks in the features department. There is pagination, good-looking app icons, seamless UI and the like. To differentiate between different apps and smartphones is important. Some publishers assume that the look and feel of an app should look the same but that is not a fact, in most cases.
As a Microsoft-designed Windows Phone, the approach of the platform is totally different. The mobile app with an iPhone app look would have looked odd, and vice-versa. Hence it is important to accept the Metro-style interface and not fight against it. Your designed app will fit in well with anyone who uses Windows Phone.
Rule No. 2: Leave Some Space
Windows Phone application design actually gives control on the overall design layout. This approach allows designers to control the goings-on. There is lack of general app icons in Windows Phone since it's an effort to make users understand that all the parts are actionable. Detailed views are available for each and every item represented.
One can use different font sizes or colors for better representation and to opt for something which suits individual tastes.
