Based on the app marketing and business advice on http://bit.ly/1yGoIDU - Go to the website for more strategies and tactics to grow your app business. In 2009 when I was working on my first app as the mobile product manager for a San Francisco Bay Area based startup, one of the first questions I had to answer was “what features do we add in our new app?” This is a very important question and the first version we developed at the startup took us 14 months to complete and when we released it in the app store, it got hammered. For the first 6 days we got nothing but negative feedback and our best rating was a 3 star. To make things worse, none of the users who downloaded the app were using the app for more than 20-30 seconds and within 2 days we lost 98% of all users (my guess was that the remaining 2% of users were our friends and family). This experience really shook us up. We had been hearing about app success stories and even before we released the app, we were already making plans of how we would be celebrating our app’s extraordinary success. Based on this experience, we decided to overhaul the complete app and start from scratch. This was the toughest decision of my life – having to throw away 14 months of work and to start again. Looking back, I am glad that we started from scratch again. The second version of the app did a lot better and you know the only difference in how we developed the two apps? For the second app we used the Lean Pirate framework to decide what features to add to the app. We created the Lean Pirate framework based on the concepts in the Lean Startup movement and the pirate metrics for mobile apps which I mentioned earlier. Lean Pirate Framework – What Features to Develop in a New Mobile App The lean startup movement suggests that before you build anything you must validate your hypothesis. More uncertain a hypothesis is, more is the importance of testing the hypothesis. While Pirate Metrics for mobile apps requires that an app focus on 5 key metrics, which are Acquisition, Activation, Retention, Referral, Revenue. So by combining these two we came up with the Lean Pirate framework whose core principles are: Your app should do just one thing really well You need to identify the ONE killer feature in your app and only develop that. Any additional features should not be developed unless they are required as per the other principles in the framework. E.g. if you are creating an invoicing app, your app should do just core invoicing really well, you shouldn’t add any features which you imagine will make the app useful. So adding project management or CRM functionality into the app will just make the app more bloated and non-user friendly Quick path to value Your app should demonstrate its value as soon as easily and as quickly as possible. Unless the user experiences the value of the app there is a large possibility that the user will get busy with something else and neve
