The user interface for a branching probabilities app became more complicated than I thought warranted the creation. The small gain in functionality over the currently available apps did not balance the complicated interface it required. I may get back to the roster app I was working on. Or, the project may be completed as a web app. I have been working on a website for my local league, the Austin Blood Bowl League.
I have had requests for an iOS version of the app. Google Play store requires a one-time payment of $25 to become a developer, Apple requires $25/year. I made the Android version because I wanted it for myself. I do not own an iOS device. It is possible that I will make an iOS version, but it is not on the immediate horizon. If others were to donate an iOS device and/or cover the cost of registering with Apple, I would gladly develop the app.
The ad-supported BB Interception app passed 500 current installs the day after its one year anniversary. The only suggestion I have received for features is to make it a more encompassing passing reference, such as including Safe Throw and fumble probability charts. I am very happy with the simplicity currently implemented. I know of one improvement I can make to the ad-free version. I can reduce download size and storage footprint. Since, it will not change any computational efficiency, this update has a low priority. Also, there are only 10 users of the ad-free. Maybe if more people purchased the ad-free version, I would make this change sooner. *hint* *hint* :)
