I am so happy to have found such a comprehensive planner for my Kindle Scribe. The included templates in the Scribe leave a lot to be desired. This planner is incredibly detailed and provides me with all that I need and more to organize my life. I cannot wait to play around with it some more. I would buy again in a heartbeat!
