LensTracky Lens Tracker

About this app

LensTracky helps you track your contact lens replacement cycles — so you never have to guess, count back on your fingers, or risk wearing expired lenses again.

Your eyes deserve better than "I think I changed them... last week? Maybe the week before?"


VISUAL CYCLE TRACKER

Progress rings for left and right eye show exactly how many days you have left. When lenses expire, the ring turns red. No math, no calendar checks — just open the app and know.


REPLACEMENT REMINDERS

Get a notification on replacement day at whatever time works for you. Still haven't swapped them by afternoon? LensTracky nudges you again automatically.


LEFT & RIGHT EYE INDEPENDENTLY

Different prescriptions or different cycles per eye? Handle each eye separately with its own timer, parameters, and reset button. Finally, an app that gets it.


PRESCRIPTION STORAGE

SPH/PWR, CYL, AX, BC, DIA, brand — all in one place. No more digging through old packaging when you need to reorder or walk into the optician.


ONE-TAP RESET

Changed your lenses? One tap and your cycle resets. A quick confirmation keeps you from doing it by accident. That's it.


SUPPORTED CYCLES

Daily, weekly, bi-weekly, monthly, or any custom interval — LensTracky fits your lenses, not the other way around.


PRIVACY FIRST

No account. No cloud. No tracking. Everything lives on your phone and stays there.


THE BORING (BUT IMPORTANT) PART

Overworn lenses are one of the leading causes of eye infections. It's not dramatic — it's just easy to lose track, especially with monthlies. LensTracky fixes that with zero effort on your part after the first setup.

Free. No subscription. No upsells. Just open it, tap, done.

If you wear contacts, you need this. Download LensTracky today.
