LensSwap: Contact Lens Timer

Track every pair, get reminded before they expire, and log how your eyes feel each day. Stay on schedule and keep your lens routine effortless.

Tired of guessing when you last changed your contact lenses? LensSwap keeps your replacement schedule on track so you never wear an expired pair again.

Set up your lenses once — daily, weekly, biweekly or monthly — and LensSwap counts down for you. When it's time to swap, you get a clear reminder. Tap once to confirm the change and the next cycle starts automatically.
