## What is LensLog?

When did you open these lenses?

LensLog is a reminder app that tracks your contact lens replacement deadlines and your spare stock. Just log the day you open a pair, and LensLog alerts you ahead of replacement day for 2-week and monthly lenses - then keeps reminding you every day until you actually swap them. Wearing lenses past their deadline puts your corneas at risk. "I can't remember when I opened these" ends here.

WHO IT'S FOR
- You keep forgetting when your 2-week or monthly lenses are due
- You wear a different power in each eye
- You've run out of spare lenses at the worst moment
- You never want to miss restocking your dailies

KEY FEATURES
Automatic replacement dates
Enter the opening date and LensLog calculates your next replacement day and days remaining, with a meter that shows the timing at a glance.

Reminders that don't give up
Alerts 3 days before, the day before, and on replacement day. Past the deadline? LensLog nudges you every single day until you log the swap - because your eyes matter.

Per-eye tracking
Different power (PWR), BC or opening date in each eye? Track left and right on their own cycles.

Stock tracking & reorder alerts
Register how many boxes you have, and LensLog tells you when to order more. For daily lenses, it predicts your stock-out date from the days you have left. Save your usual shop's link and restock in one tap.

Comfort log
Record wear time and comfort to see, on a chart, which day your comfort starts to drop - your replacement cycle suddenly makes sense.

Photo management
Add a photo of the box or blister pack (the subject is cut out automatically) to tell lenses apart at a glance.

Home screen widget
See your next replacement day and days left right on your home screen.

Daily eye care tips
A practical eye and lens care tip, every day.

Free to use (track 1 lens type). Go Premium for unlimited lenses, per-eye tracking, purchase links, and an ad-free experience.

Note: This app does not provide medical advice. Always follow your eye doctor's instructions for wear time and replacement cycles.

Clear vision, zero worry.
