Advertised as free
But as soon as you open the app, it asks you to install another one and pay .99 cents. When I declined there was an obnoxious watermark added over the graph to prevent data from being usable in any professional setting. I know .99 cents is only .99 cents but advertising as free and then making the app unable to be used is shoddy business practice. Buy your own coffee, I’ll just use graphing paper. Alright. I had not considered that perspective. Changing my negative review to a neutral review since I was not a fan, but the reason for my chief complaint is understandable.
