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 reminds you — every single day if it has to — 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: -2.25 → -2.50 (increased by 0.25)". Just the numbers — never advice. LEFT AND RIGHT, TRACKED SEPARATELY Real life isn't symmetric. One lens tears, the other is fine. Tap "I replaced my lenses" and choose Both, Left only, or Right only — in three taps. Each eye keeps its own countdown. No other tracker does this properly. REMINDERS THAT DON'T GIVE UP - An early heads-up a few days before the change date - A reminder on the day itself - A gentle nudge every day after, until you mark it done All at the time you choose.
