With the market for apps being extremely crowded and the quality bar rising continuously, the era of the get rich quick apps have long gone by and the real challenge for the marketers/ App Entrepreneur is to gain a significant mindshare of their user base. This is where the significance of Mobile App retention comes in. With so many apps to download and use on the app store, most of the apps get lost among the collection of apps downloaded by the user or gets deleted soon after download. It is estimated that in case of most apps within a period of 3 months, over ¾th of their customer base is long gone, which in all sense affects your ARPU and in turn your net revenue. App Entrepreneurs have a retention problem rather than a discovery problem. The ASO techniques are extremely important in getting apps visibility on the app store and maybe a few downloads but with the plethora of apps on the app store and the relatively low barrier to delete an app from a mobile, the major challenge for an app maker/ marketer is to increase the user retention and with it the Lifetime value of their users.
