About
Sixty-five days since your last bleeding. Not day 14 of anything.
Meridian is a log for the years when your cycle stops agreeing with the calendar. It counts
days, not cycles. Its only reference is your own median, never a textbook range.
WHAT IT DOES
1. The day is the unit. Every screen answers one question: how many days since your last
bleeding, and how that sits against your own months. Nothing is numbered against a textbook
cycle, nothing counts down, and no date is ever promised.
2. A report you can hand to your doctor. A PDF measured in months instead of cycles, with your
bleeding, your symptoms and your medication in one place, and with the symptoms that have
nothing to do with a cycle drawn inside the same chart. It works with no connection, and if your
plan ever ends your records still leave with you as CSV and as a plain PDF.
3. Not bleeding is a first-class entry. "I have not bled this month" is a button on the home
screen. It stays where you put it, with no countdown and no question about pregnancy.
4. No caps and no labels. A bleeding of 22 days is stored and drawn. A gap of 400 days is
stored and drawn. Nothing here is ever labeled abnormal, no warning triangle appears over your own
body, and no screen carries a verdict about it.
5. Your sleep and your heart rate variability, read from Apple Health, turned into one number
for today with the reason written next to it. No watch needed to use the rest of the app.
6. Hormone therapy as a state, not a footnote. Your months before and after, side by side,
described and never judged.
7. It says "We do not know yet" when it does not know. When your recent intervals disagree with
each other, Meridian shows you the spread they make and refuses to draw a date on top of it. A
window arrives the month your own months hold together, and not before.
WHY MERIDIAN
The meridian of life is the middle of it, understood as the highest point of the arc rather
than the beginning of the end. A meridian line is also a real instrument: a strip set into a
cathedral floor with a hole of light above it. Florence built one in 1475 and Bologna a much
bigger one two centuries later, both for the same reason, because the calendar had drifted away
from the sky and somebody had to measure what was actually happening instead of trusting the
chart. That is the whole app.
NO ACCOUNT AND NO SERVER
There is no sign-up, no email and no password. Your records live on this iPhone. Nothing is
uploaded to us because there is nowhere to upload it to. No chatbot: your symptoms never enter
a language model. Your data can be exported to CSV and PDF at any time, including after you
cancel.
WHAT IT COSTS
89.99 USD per year, or 13.99 USD per week. Both renew automatically until you cancel, and you
cancel in your Apple settings because we never see your card. There is no free trial, which means
there is no surprise charge on day eight either. Before the price ever appears you have already
seen your own 24 months drawn on screen, and the app has told you plainly whether it is a fit for
your situation. If it is not for you, ask for a refund within 30 days. The app has a screen that
explains exactly how, and Apple is the one who handles it.
WHAT MERIDIAN IS NOT
It is not birth control and it is not a fertility app. It does not diagnose anything, it does
not tell you what your body should be doing, and it is not a medical device. It is a general
wellness app that records what happened and shows it back to you.
