I am using this app for many years, I was always pretty happy with it.But recently, since this year it gets slower and slower, until the moment now where it becomes sort of a frustrating app, that is so slow and giving you results and being able to make any changes, that it takes a half to finalise the daily measurement.In addition to that there is zero support, writing to the company, results and no answer to your issues with the app.For example it takes up to 10 minutes to change three 15 minute segments within the gauge. And more often, you can’t even click the gauze, nothing happens if you click it.You can click for one to 2 minutes until it then finally opens the settings of the 15 minutes segment adjustment: to make one change and then stuck to make any other change fire minutes, any other change does not get accepted.
