The app has various long standing bugs and usability quirks. It has a premium version with additional mostly cosmetic features, and a paid platform for use by healthcare workers. There is also data lock-in, so you cannot switch to another app. Their export to .xls function does not include much of the data contained within in the app. Data seems to expire after one year, as it cannot generate any reports earlier than that. They said these issues would be fixed and that there would be a web interface _years ago_. This app is proprietary trash and _nobody_ should be using it.
