Tend is a private journal for pain, fatigue, fog, sleep, mood and stress. It finds patterns across weeks of your own entries, then gathers them with your medications, labs and questions into one page to bring to your next appointment.

Everything Tend records
Nothing to set up Skipped stays skipped Silent until it is sure
An illustration of a Patterns card, not your data.
Tend records pain, fatigue, fog, sleep, mood, stress, where it lives, flares, morning, afternoon, evening, medications, supplements, labs, visits, questions, the night before, practices, movement, pressure, weather, pacing.
Six questions, the whole day
Pain
& where it lives
A body map, front and back
- 0 to 10, or skipped
- Painted on a body you can see
- Morning, afternoon, evening
- Today's peak
- Which side, and how far it spread
Fatigue
& fog
Two scales, both optional
- How much you had in you
- How hard reading was
- Fog Mode, when it is bad
- Spoken entries on the worst days
- What you managed anyway
Sleep
& the night before
Four fields
- Hours, roughly
- How many times you woke
- Quality, 0 to 10
- Whether you woke up rested
- What you took to get there
Mood
& stress
Two scales, never a verdict
- How the day felt to be inside
- What was pressing on it
- More than one moment per day
- A day can hold two feelings
- Left blank stays blank
Medications
labs & visits
The whole paper trail
- Doses, and whether you took them
- Supplements alongside them
- Lab results, with their dates
- Appointments, past and next
- The questions you meant to ask

What the app says to you
Every line written for a bad day.
“You showed up. That counts.”
“It won't always be this loud. Flares pass. Rest is the work.”
“A day can hold more than one feeling.”
“Gently now. Nothing to catch up on.”
“Fixed. Days are allowed to change.”
“Let it be small today. Flares pass. So will this one.”
“Today is weathered. Rest is the work.”
“Noted. The day can change.”
These are lines the app itself says, not customer quotes. Tend has not launched, so there is nobody to quote and no reviews to show.

Frequently asked questions
What is Tend?
Tend is a private iPhone app for people living with fibromyalgia. It combines an optional daily check-in, records for medications, labs, visits and questions, conservative summaries of your own entries over time, and a printable letter to bring to a doctor's appointment.
Does Tend collect or upload any data?
Tend requires Apple or Google sign-in and syncs your record to your Tend account. Beginning with Tend 1.0.1 build 8, six product actions are linked to the account UUID in PostHog, but answers, notes, health details, email, name, location and free text are excluded. There is no advertising or cross-app tracking. The public website separately counts limited, anonymous, cookieless pageviews. Optional weather sends a rounded approximate location and IP directly to MET Norway, never health data. You can export or delete your record from Settings at any time.
What does a check-in involve?
You record how the day went across pain, fatigue, fog, sleep, mood and stress. Every field is optional, so a half-finished day still counts, and on a foggy day you can speak an entry instead of typing it.
Does Tend give medical advice?
No. Tend is a self-tracking tool. It records what you enter and shows you conservative summaries of your own entries. It does not diagnose or treat anything, it is not a medical device, and it is not a substitute for care from your own doctor.
What does Tend do with the patterns it shows?
Every summary is computed on your iPhone from your own entries and nothing else. Skipped answers stay missing rather than counting as zero, findings carry the number of days they rest on, and a card stays silent until it has enough answered days. Tend describes association and timing, never cause, and a pattern in your own days is not a diagnosis.
How much does Tend cost?
Tend is currently offered at no cost and contains no in-app purchase.
