We know that some of you really loved it. We loved it, too. We needed it. But, there is only that much we can do on top of Google's app. Appser can never become a top-of-the-line product. And what's the point of working on it if it can never get there.
Therefore we decided it's in everyone best interest to cease development and remove the app from the store.
On a lighter note, we just updated Presentation Note and are working on some really cool products that will launch later this year.
