Mask Minder: Masking

Mask Minder reminds you to mask up the moment you walk into a building — automatically, privately, on your device. Now with calendar-aware alerts for high-risk events.

Mask up — automatically.

Mask Minder is a privacy-first mask reminder for the immunocompromised, COVID-conscious, and anyone who just doesn't want to walk into a doctor's office bare-faced.

HOW IT WORKS • Add the indoor places you visit (or let Mask Minder learn them) • When you arrive, you get a reminder before you forget • Optional: connect your calendar for pre-event alerts before flights, appointments, and other high-risk events

SMART, NOT ANNOYING • Motion detection knows whether you walked into a building or are still in the car • No reminders when you're already home • Customize schedules so the app respects your day

PRIVATE BY DESIGN • Location, motion, and calendar data never leave your device • No accounts. No servers. No tracking. • Optional Face ID lock on your visit history

MASK MINDER PRO ($4.99 one-time) • Outbreak intelligence — local respiratory virus trends • Calendar-based mask alerts for high-risk events • Mask insights — see your masking habits at a glance • Custom schedules and granular control • Premium app icons • Face ID lock

Built by one developer who masks every day.
