The idea is not improvised, is based on a theory that was raised last year when the exempleado Google, Tristan Harris proposed it as a way to return the cell less addictive. The idea of Harris basically says that if the phone is more “bad” or less attractive, we will no longer use it. An article in The New York Times reinforces the strategy and according to the author, Nellie Bowles, her-yes it worked.

The concept is based on neuroscience, which ensures that as animals we are (rational, but in the end animals) respond to color stimuli. Less stimulus, less attraction. The principle has already been applied by manufacturers, how is the case of the Blloc Zero18, a cell completely minimalist with a black & white screen to encourage you to spend less time using the device.

Less addiction, the new trend

All the giants of mobile technology seem to be looking for the way to return their platforms more efficient, and ensure that the users spend less time using their cell phones. In the Google I/O the company presented several options to detach the people from the phones; so did Apple just during the WWDC 2018 where he presented the apps for iOS 12 Screen Time and Do Not Disturb button to tell the user the amount of time you spend using the mobile device; also the social networks such as Instagram have the same goals.

Well, until specific apps for them have been created as is the case of Siempo, an application that in addition to helping you better manage your phone, to use it less, it also makes your phone “annoying” to inhibit its use.
