A long while back we created an intiative tracker app that came to this world as a sister app for ProDnD Dungeon Generator. We recently released a newer version of this app.
We heard a couple of common complaints from you and changed a variety of things. You can find more on our update log here. Without further ado here's a gif of how thi app works.
You can get the Android app here. (No iOS yet.)
