About TaskBlue
TaskBlue is for parents whose child has their own iPhone. During focus, for example at school or during homework, the distracting apps disappear from your child's iPhone. Everything else keeps working. Every focus hour removes about 100 g of plastic from the sea. HOW IT WORKS • Set it up once on your child's iPhone, no parent app needed • Pick the distracting apps, for example games and social media • During focus they disappear from the home screen, afterwards they are back • Calls, messages and maps keep working WHEN FOCUS RUNS • Place: automatically at school or tutoring • Schedule: fixed times, for example for homework • Lock Up: until a time you set • Manual: hold the circle for 3 seconds BLUE • Blue is a little sea turtle who lives in your child's sea • Every focus makes Blue's sea cleaner and Blue happier • With the plastic collected, your child gets Blue hats, costumes and colors • No real money and no purchases involved, only focus time • Widgets show Blue on the Home Screen and Lock Screen ALARM • Keeps ringing until your child scans the BlueTag • A morning focus can start right after THE BLUETAG • Small NFC tag without a battery that stays with you • End focus early: with the BlueTag or your parent code • For real emergencies there is an emergency exit, three times in total • Get the BlueTag at taskblue.app OCEAN IMPACT • Every focus hour funds the recovery of about 50 g of ocean plastic, up to 5 kg a month • Your child sees in the app how much plastic they have pulled out of the sea PRIVACY • You see neither your child's location nor their messages • Location stays on the iPhone • Uses Apple's Screen Time framework
