User reviews

Great Idea!

Since this app is in its infancy stages, it starts with a great concept. It would be nice to be able to edit logged data and the timeline at the bottom of the graph is illegible, it should be readable and or free flowing when the user moves the cursor back-and-forth. I will purchase this app, hoping that the developer will make improvements upon this app as I have not seen another one like it yet.
