Design - HIGH IMPACT
The most fundamental of all marketing is going to be the design of the app. Icon and screenshots make a huge difference in conversion. Think about it – every single app has the same basic opportunity from the very start and will get about the same number of eyeballs as the apps released on the same day in that category.
The difference is when people see an icon they like with a name that’s catchy and maybe a lot of positive reviews (we’ll get to this later). They open the app and see some great screenshots and a description. THIS IS YOUR FIRST IMPRESSION! Please make sure your design is done well before you start getting into the external stuff.
TIP: You don’t need a fantastic app to make it look beautiful. Hiring a professional designer to do some really nice high-resolution screen shots can make any app look awesome and exciting. You can illustrate someone using your app on a photoshopped iPhone screen or whatever – just make it look great.
