Works, but not the most ethically safe
Dont get me wrong; this app does do what it claims to do. However, hypothetically speaking, "consent" can be easily compromised, such as in blackmail. Good for the one who wants to keep constant tabs on a person, bad for the poor sap who knows he or she cant escape the half-hourly or ten-minute checkup.
