Scam

App is inaccurate on time and frankly makes no sense. Paid for upgrade and it is the same, but no ads. Now it crashes constantly and I have to delete and download again therefore losing all my data.
I have no idea what the measurements used are but it is not minutes/hours. The notifications to say you are over your time do not work. Essentially this app is garbage. Save your time and money.
