Pester — Reminders That Nag

Lucas Moeller

About this app

DESIGNED FOR PEOPLE WHO FORGET

Built by a parent of a kid with ADHD who needed reminders that actually refuse to be ignored. If you or someone you love dismisses notifications and immediately forgets, sets reminders that never fire loud enough, or needs aggressive, repeated prompts to stay on track — Pester was made for you.

No categories. No tags. No projects. No planning features. Just a title, a time, and relentless persistence.

Unlike quiet notification apps that ping you once and give up, Pester keeps nagging — firing the same reminder every few minutes until you mark it done or snooze it. No more "I'll do it later" followed by "I completely forgot."

WHAT MAKES PESTER DIFFERENT

• Auto-snooze: Set a reminder and walk away. If you ignore it, Pester fires again in 1, 5, 10, 15, 30, or 60 minutes — your choice per reminder. It doesn't stop until you act.

• Lightning-fast input: Type "Call mom in 30 minutes" and Pester understands. Natural language parsing means you spend less than 3 seconds creating a reminder. Or tap a quick-time button — Morning, Noon, Evening, +1 hour — and you're done.

• Action from your lock screen: Snooze for 10 minutes, 1 hour, 3 hours, or tomorrow — all from the notification shade. No need to open the app. Or tap Done and move on.

• Repeating reminders: Daily, weekdays, weekends, specific days of the week, or monthly. Your "take vitamins" reminder fires every morning without you lifting a finger.

• Survives reboots: Restart your phone and your reminders are still there, still firing on schedule. Most reminder apps silently break after a reboot — Pester doesn't.
