In the recent past, a lot of research has demonstrated that an increasing amount of people, especially teenagers and young adults, is suffering from technology addiction. This new form of dependence can cause various health problems, starting from lack of sleep or decreased communication, and ending with depression, obesity and Attention Deficit Hyperactivity Disorder. To keep under control this problem, and possibly overcome it, different solutions have been experimented during the years. The most adopted proposal is represented by Digital Self-Control Tools, that are pieces of software, implemented as smartphone application or web extension, that help people in reducing their technology overuse by adopting interventions like timers, alarms, blocks of incoming notifications and screen-locks.
