Klar App
Read full descriptionHide full description
Klar is a family task app built around one idea: everyone knows what they need to do. A parent creates the family, assigns tasks to each member, and sets a deadline. Klar handles the rest — sending reminders that get more frequent as the deadline approaches. When a task is done, the parent is notified. No nagging required. BUILT FOR FAMILIES — Assign tasks to any family member with a deadline — Recurring tasks — daily, weekly, biweekly, or monthly — Three roles: Owner, Parent, and Child, each with the right level of control — Everyone gets their own view — children see their tasks, parents see the full picture REMINDERS THAT ESCALATE Klar reminds the right person at 7 days, 3 days, 24 hours, 6 hours, 1 hour, 30 minutes, and 15 minutes before a deadline. Miss the deadline and both the assignee and parents are notified immediately. EARN MONEY FOR CHORES Add a compensation amount to any pool task. Kids claim what they want to do and earn real money. Parents pay with Swish directly from the app. NO ACCOUNTS REQUIRED No email addresses, no passwords. The family owner creates member profiles and each person gets a unique join code. Enter the code once and you're in. HOME SCREEN WIDGET See your open tasks without opening the app. Parents see their children's tasks at a glance. Children see their own.
