Lensday - Track Your Lenses

BasilBase

About this app

Lensday tracks your contact lenses on your watch, so you always know how many days are left
before you should change them.

A glance at your wrist replaces the mental arithmetic. No more "was it three weeks ago, or
four?"


A RING PER EYE

The home screen shows two countdown rings, one for each eye. The number in the middle is the
days remaining; the ring empties as the lens gets older. Left and right are tracked
completely separately, because they rarely start on the same day.


ON YOUR WATCH FACE, NOT JUST IN THE APP

• Tile — swipe from the watch face for both countdowns at a glance
• Complication — put the days remaining straight on your watch face
• Optional reminder — a nudge in the morning when a lens is due

The reminder is off until you turn it on. Lensday uses no battery while it is closed, and a
reminder adds one short check each morning — a very small, ordinary amount.


BUILT FOR REAL LENS ROUTINES

• Pick your lens duration — daily, weekly, two-week, monthly or quarterly
• Mark a new lens the moment you open the blister, per eye
• Note when you take lenses out and put them back in
• Keep a running count of how many lenses you have left in the box
• See the full history of every change, in and out, with dates
• Overdue lenses turn red and keep counting, so you know it has been three days and not one


YOUR PRESCRIPTION, ON YOUR WRIST

Store the details for each eye so you have them when you reorder or sit down at the optician:

• Brand
• PWR (power)
• CYL and AXIS for astigmatism
• DIA (diameter) and BC (base curve)

No more digging out the box or the old prescription slip.


MADE FOR THE WATCH

Lensday is a standalone Wear OS app. It runs on the watch itself — no phone app to install,
no pairing, no account, no setup. Open it, glance, done.

COMPLETELY PRIVATE

Everything Lensday stores lives on your watch. There is no server, no account, no analytics,
no advertising and no tracking of any kind. The app has no internet access at all. Your
prescription never leaves your wrist.
