it never suggests a dose

Your own data, given back as a letter.

Comfrey reads the diabetes data you already generate. Once a week it writes you a few plain sentences about what tends to move your blood sugar. Fewer numbers than you started with.

Comfrey is not open yet. Join the list and you will hear when the first letter can be written from your own record. There is no account and no card to read it. See what it reads.

A sample letter, written from one person's record.

this week's letter

Sunday, sent at 08:00

Your mornings held steady this week, start to finish.

On the two nights you slept badly, the evenings afterward drifted higher than usual — though a later dinner could also explain it.

Weekends looked calmer than weekdays. Saturday in particular ran even, and nothing you noted seems to pull against that.

Very little else changed, and that is worth knowing too. A quiet week is a real answer, not a missing one.

Next week I will keep watching how the nights before a busy day tend to go. This is what your glucose does; the diary is what starts explaining why.

Comfrey

the shift

Every other tool turns your life into numbers. Comfrey turns the numbers back into life.

A sample of one day's readings in mmol/L — one every five minutes, forever.

The same week, read back to you.

“Your evenings ran higher on the days you skipped lunch. Two of those followed a short night, which could also explain it.”

your record

It reads what you already have. You do not start over.

Bring the data your meter or monitor already keeps. Comfrey works from the record you own, and the diary only adds the small context numbers cannot hold.

what it reads

Your glucose history, from where it lives now.

A short export still works. If it covers fewer than fourteen days, Comfrey says so plainly and writes anyway, noting that the letter will be short.

Tapping here changes this sample only; nothing is recorded. In Comfrey the note is skippable any day, with no reminder about it in the letter.

the question

Between letters, ask your own record anything.

In your own words, about your own history. You get a sentence back, drawn from your data — never a recommendation, and never a dose.

A sample exchange, from one person's record.

you — Do weekends look different for me?

comfrey — They do. Your Saturdays and Sundays ran steadier than weekdays over the last month, with the calmest mornings of the week.

you — How much should I dose before a big dinner?

comfrey — That one I leave alone. Dosing is between you and your clinician — I can show you what past dinners tended to do, if that helps the conversation.

Comfrey holds this line on every dosing question, by design.

the discipline

What Comfrey will not do is the point.

Living with diabetes is enough work already. Comfrey is built to lower the volume, not add to it.

Never a dose

No correction, no ratio, no target, no threshold. Those belong to you and your clinician, and Comfrey stays out of them.

Never a nudge

It does not grade your day, cheer, or warn. A quiet week reads as a quiet week, not a problem to fix.

No streaks or scores

No points, badges, or time-in-range leaderboard. Missing a note breaks nothing and is never mentioned back to you.

No red zones

Nothing on your record is labelled abnormal or coloured like an alarm. The letter describes; it does not judge.

the plan

One plan, priced to be forgotten about.

When Comfrey opens, the first letter comes with no account and no card. If you want the next one, and the ones that follow, one plan covers everything.
