LensTime: Contact Lens Tracker

Contact lenses don't come with a memory. LensTime does. If you've ever stared at a lens and thought "wait, when did I put these in?", LensTime is for you. It quietly counts down the days for each eye and keeps reminding you until you actually change them. No ads. No subscription. No account. Just a reminder that works. TWO PROBLEMS, SOLVED 1) "How long have I been wearing these?" Monthly and biweekly lenses expire on a schedule, no matter how often you wear them. LensTime tracks the days for you, so you stop guessing and stop wearing lenses past their time. 2) "Did my numbers change? Did I have astigmatism?" Nobody remembers their old prescription after an eye exam. LensTime keeps every exam and shows exactly what changed: "Left SPH up 0.25". Just the numbers, never advice. LEFT AND RIGHT, TRACKED SEPARATELY Real life isn't symmetric. One lens tears, the other is fine. Changed just one? Tap that lens in the case, say why if you like, and tap "I Changed the Left Lens" or "I Changed the Right Lens". Only that eye starts over. The other keeps its own countdown. Changed both? "I Changed Both" is right on the home screen. REMINDERS THAT DON'T GIVE UP - An early heads-up a few days before the change date - A reminder on the day itself - After that, a nudge every day for a week, then weekly, until you mark it done All at the time you choose. Already changed it? Mark it straight from the notification. LOG AN EXAM IN SECONDS In a hurry? Take a photo of the prescription and add the numbers later. Every field opens at your last exam's value, so only what changed needs a turn of the wheel. Cylinder and axis stay folded away unless you have astigmatism. KEEP YOUR PRESCRIPTION HANDY SPH, CYL, AXIS, base curve and diameter, all on one screen and ready to copy when you reorder.
