Why the new app?

This app appears to have the same description and functionality as the old version of the app, which was renamed “GraphicalGW”. Oddly, the old app has the exact same icon and name as this brand new app, which makes no sense to me. Vernier, why double up on apps? Why not keep the original name with the original app?
