It captures the key features of behavioural addiction — daily-life disturbance, withdrawal, tolerance, loss of control — adapted to smartphone behaviour. Scores from 10-60 fall into three bands: normal use, at risk, and likely addiction (≥32).

About the online SAS-SV
The SAS-SV measures problematic smartphone use across daily-life disturbance, withdrawal, tolerance and loss of control. It's not about screen time alone — it's about whether your phone use is starting to work against you.
This free version uses the standard 10-item SAS-SV. You answer how strongly you agree or disagree with each statement, and you get a total score from 10 to 60 plus a severity band.

Important: Smartphone addiction is not a formal diagnosis but problematic phone use is a well-studied behavioural pattern. If your score is high, consider whether you're also experiencing depression, anxiety or loneliness — addressing those usually helps.
