Lens Due

Lens Due helps you track contact lens replacement dates for each eye—left and right can have different schedules—and reminds you locally when a lens is due. Mark a replacement in one tap to reset that eye’s timer.

WHAT YOU CAN DO
• Set a schedule per eye (daily, weekly, biweekly, monthly, or custom days)
• See remaining days on Today
• Get on-device notifications when a lens is due (optional day-before reminder)
• One-tap “Replaced” to restart the cycle
• Optional per-eye stock count and replacement history
• Home-screen widget showing left/right days left

BUILT TO STAY SIMPLE
• No account. No cloud sync. Your schedules stay on your device.
• Core reminders are free—no subscription lock on replacement alerts.
• Made for daily / biweekly / monthly contact lens wearers who want a clearer timer than a plain calendar event.

NOT A MEDICAL DEVICE
This app is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Always follow the replacement schedule and care instructions from your eye care professional and lens manufacturer. Lens Due is a personal reminder tool only.

Privacy: data stays on your device.
