As answered by people managing Codédex and Screenwise App.
Screenwise App's answer:
Screenwise turns screen time into something children earn through learning. Instead of only blocking apps, it helps parents reduce screen time arguments while giving children regular practice in times tables, MTC, and 11+ maths.
Screenwise App's answer:
Most parental control apps only restrict access. Screenwise adds a clear learning incentive, so children work towards screen time by practicing maths. That makes it useful for parents who want less conflict, better habits, and real educational value from the same app.
Screenwise App's answer:
Screenwise is mainly for parents of primary school children in the UK who want to manage screen time while helping their children improve multiplication, prepare for the MTC, and build stronger maths habits.
Screenwise App's answer:
Screenwise was created to solve two common parent frustrations at once: too much screen time and the daily struggle to get children to practice maths. The idea was simple: connect screen time to learning, so children stay motivated and parents spend less time negotiating.
Screenwise App's answer:
Use this only if accurate: Screenwise is built as an Android app with modern mobile technology, focused on reliable parental controls, app usage management, and a simple learning experience for families.
Screenwise App's answer:
Screenwise is primarily used by families who want to manage screen time while encouraging children to practice maths. It can also be adapted for educational settings where teachers want to motivate students with short multiplication practice.

I've been learning Python on a website called codedex.io for about 6 months. It's been great for me so far. I just started on Classes and Objects. Give them a try, you might like them. Source: over 3 years ago
