I have been using this app for years. It was great, and then the ads started. Now, I cannot open it to log a single symptom without having to cancel out of at least four different ads for the premium version. The only reason I am still using it is because I don't have a way to export all of my information from past years. From a business perspective though, I'm not the one paying money, so me deleting the app will not make a difference. But my cycle isn't a business decision that I make :/
