Owl was I said, I will not lose my keys. So I installed the application g-tag on my smartphone, set the thing and ... I have my smartphone that sounds as soon as I move away from my pants in lequl is usually found my keys. That is when I go to bed. As long as I have not given my pants, the smartphone rings occasionally. The application is intrusive if one puts geolocation (I take it off when I do not have) and if not, impossible to retouver his keys jingling key door. BOn, therefore, it does not make much sense. But it works in the unnecessary.
