Your symptoms should not be trapped in yet another app. Tend is the mood and symptom diary that writes every check-in into Apple Health itself - moods as State of Mind, symptoms as real Health samples. Your record is yours, it works with every Health-connected app, and it outlives Tend itself.
A CHECK-IN THAT TAKES SECONDS
Log how you feel in a couple of taps. Add what is going on around it - energy, stress, sleep quality - and whether you took your meds. On harder days, Tend asks less of you, not more. Start tonight: one check-in takes seconds, and it is yours to keep.
SYMPTOMS, NOT JUST MOODS
Track dozens of built-in symptoms - headache, fatigue, nausea, bloating, dizziness, brain fog, and more - each saved to Apple Health as a proper sample. Living with something the list does not cover? Add your own custom symptoms. Tend was built for migraine, IBS, PMDD, chronic fatigue, and anyone whose symptoms do not fit a tidy box.
PATTERNS YOU CAN ACTUALLY READ
Tend quietly looks at what your iPhone and Apple Watch already know - steps, active energy, sleep, mindful minutes - and connects it to how you said you felt. No dashboards to decode. Just plain sentences, like "Your mood tends to be brighter on days you walk more." Tend shows associations in your own history, so you can spot what tends to move with what - it never claims causes, and it never tells you what to do about your health.
A STREAK THAT FORGIVES
Meet Sprout, the little plant that grows with your habit. Miss a day? Sprout does not wilt, guilt-trip, or reset you to zero. Life with a body is unpredictable - your streak bends instead of breaking, and coming back is always celebrated.
EVERYTHING, FROM THE FIRST CHECK-IN
One yearly plan, or a one-time lifetime purchase. No monthly nagging, no ads, and nothing about you is ever sold. That includes all of it:
- Unlimited mood and symptom check-ins

- Links between your meds and how you feel, from your Health medication log
- Next-day patterns for caffeine, drinks, and sleep
- Detailed symptom options with severity and time ranges
- A doctor-ready summary to bring to appointments, with private on-device AI recaps

BUILT FOR EVERY BODY
Tend is designed with deep accessibility: VoiceOver labels throughout, audio descriptions for every chart, full Dynamic Type, and calm animations that respect Reduce Motion.
PRIVATE BY DESIGN
No account. No sign-in. Your health data stays in Apple Health, on your device, under Apple's protections - Tend has no server that stores it and never uses it for ads or tracking.
Tend is a wellness diary, not a medical device. It does not diagnose, treat, prevent, or cure any condition, and it is not a substitute for advice from a qualified health professional. If something feels wrong, talk to a person, not an app.
