Contact Lens Timer & Reminder

Lens Timer keeps count of the hours your contact lenses are in, so you stop at the daily limit your optician gave you. Tap when the lenses go in, tap when they come out. The app watches the clock so you don't have to.

Works with dailies, two-weeklies, monthlies and overnight lenses from any brand: Acuvue, Dailies, Biofinity, Air Optix and the rest.

ONE TAP, ANYWHERE
Lenses in or out from the app, from the home-screen widget, or straight from the notification. The widget is free and stays free.

COUNTS DOWN TO YOUR LIMIT
A contact lens timer that counts down, not up. Set your limit once: 12 hours by default, or whatever you were told. It shows the lens wear time you have left today, live, and turns red when you're past it. No mental arithmetic.

REMINDERS THAT ACTUALLY REMIND
Real notifications, not silent pop-ups: an hour before the limit, at the limit, then every 30 minutes past it until the lenses are out. A bedtime check at 11 PM if they're still in, so you don't fall asleep in them. Overwear is what every optician warns about; this is the contact lens reminder that catches it. Still in after 18 hours? It asks whether you're still wearing them. All adjustable, with quiet hours.

FRESH PAIR, FRESH CASE
Pair 3, day 26 of 30, fresh pair on Tuesday. Lens Timer keeps the replacement schedule for two-week and monthly lenses, or any interval you set, and reminds you the evening of the last day, with Replaced and One more day buttons. Replace contact lenses on time, every time. A lens case reminder every 90 days, or as often as your optician suggests.

RUNNING LOW
Count the pairs in the box once. It counts down, one per day worn for daily disposables and one per pair opened for the rest, and nudges you at five left.

OVERNIGHT LENSES
Wear ortho-k lenses at night? Overnight mode flips the timer: a minimum of hours per night instead of a maximum per day, and a bedtime reminder to put them in.

HOW YOU'RE DOING
A contact lens tracker for the numbers that matter: average hours per day, days within the limit, your streak, and the average wear on each pair. Forgot to tap? Fix the times in a few seconds. Share a summary with your optician at your next eye exam; you get a reminder the day before. Back up everything to a file and restore it on a new phone.

WHAT IT DELIBERATELY DOES NOT DO
- No account, no login, no email
- No cloud, no sync, no servers
- No ads
- No analytics, no crash reporting, no tracking of any kind
Everything stays in the app's private storage on your phone.

Lens Timer records what you do. It is not a medical device and gives no advice beyond the limit you entered; follow your optician's instructions.
