Tend: Fibromyalgia Companion

Track how you feel, notice your own patterns, and prepare for appointments in one private place. No ads, ever; your record is yours and reaches every device you use.

Tend is a quiet, private journal for living with fibromyalgia.

Most health apps meet a hard day with red badges, broken streaks, and dense charts. For a body already turned all the way up, that is the opposite of help. Tend is built the other way. It is warm and dim like candlelight. It leads with how you feel, not what you scored. It never scolds, and it welcomes back the day you return most of all.

A FELT CHECK-IN, NOT A FORM Tell Tend how today is — pain, fatigue, fog, sleep, mood, stress — in as much or as little detail as you have in you. Every field is optional, so a half-finished day still counts. Mark where the pain lives on a body map, note a flare, and add another moment when the day changes its mind. On a foggy day, you can simply speak instead of typing.

YOUR OWN PATTERNS, HONESTLY Over weeks, Tend reads your own entries back to you: how your metrics have moved, which areas have carried the most, and how sleep and pain have sat beside each other. If you connect Apple Health, read-only sleep, steps, and resting heart rate can sit beside what you report. A separate Apple Watch permission can add an overnight signal compared only with your own baseline; raw heartbeat data remains in HealthKit. Every finding carries the number of days it rests on. Skipped answers stay missing rather than counting as zero, and a card stays silent until your own record can support it. Tend describes timing and association, never cause.

GENTLE THINGS, WHEN YOU CHOOSE Open a body-area movement library with 34 illustrated options, or enter one of four short practices: paced breathing, a sleep wind-down checklist, slow self-myofascial pressure, and a pacing check. They are optional and self-directed, never a streak or an escalating plan. Tend does not prescribe them or claim that a practice will change your symptoms.

SOMETHING REAL TO HAND YOUR DOCTOR Keep your own record of medications and supplements, lab results, visits, flares, and the questions you think of at 2am. When an appointment comes, Tend composes a clear, printable letter you can bring — so the conversation starts from something real instead of a blank page.

PRIVATE BY DESIGN Sign in with Apple or Google. No password is ever created or stored, and Hide My Email is fully supported. Your record is kept on your iPhone and in your own Tend account, so a lost phone does not mean a lost record. No advertising or sale of health data. Six app-use events are linked to the Tend account UUID; they exclude health answers, notes, location, email, name, and free text, and you can stop future analytics in Settings. Apple Health can be read if you ask, read-only, and never written to. Optional weather uses a rounded approximate location with MET Norway and Open-Meteo and never sends health data. Export everything as JSON and CSV, or erase all of it, any time.

BUILT FOR THE HARD DAYS Fog mode strips the check-in down to one thing at a time. Flare mode dims the whole room and holds your own plan. An optional lock keeps your record behind Face ID or your device passcode.

A NOTE ON WHAT TEND IS Tend is a self-tracking and general wellness tool, not a medical device. It does not diagnose, treat, or tell you what to take, and it is not a substitute for your own doctor's care. How its summaries are made — and what they will not claim — is explained plainly in Settings.

Tend keeps real crisis resources one tap away, in Settings, for anyone who needs them.
