Which month had the largest increase in the number of "Happy" users ?

Hope you are keeping well. I just wanted to give you an update on the progress so far of our app initiative. It has got off to a somewhat difficult start as you can see but we are confident that the upcoming update, when released, will solve some of the technical issues that we've been having. This should reduce the volume of IT complaints and increase the number of users using the app. We're currently under budget with a total development spend of $417,150. As you know this app is a direct replacement for a commercial solution (Ksort) which we were paying around $30,000 in licences per month to support. In a simplistic sense, we will be "breaking even" on the cost of this new app in just over a year, which is great news. However, this is not just a cost-saving exercise. This app has a purpose and our biggest priority is ensuring that our users are at least as happy with the new solution as they were before.
