SymptomLog is a private daily diary for one person living with one long-term condition. Log how the day actually went in under a minute, then show your doctor a record instead of trying to remember. At setup you choose your condition — migraine, IBS and gut health, autoimmune, fibromyalgia, chronic pain, endometriosis, allergies, mental health, or something else — and your starting symptom list is built around it. WHAT ONE DAY LOOKS LIKE Tap the quick-log card on the home screen. Pick one of five moods, from Terrible to Great. Slide each symptom you track from 0 to 10. Tap anything that may have played a part: poor sleep, stress, weather change, a certain food, alcohol, exercise, a missed dose, menstrual cycle, dehydration, overexertion, travel, illness. Add a note if you want one, then save. That's the whole thing. The home screen shows your logging streak, your total days logged, and a week-at-a-glance strip, so you can see which days you missed and go back and fill them in. An optional reminder at a time you choose nudges you once a day. IT STAYS ON YOUR PHONE There's no account, no sign-up and no cloud sync. Your entries are stored on this device — no copy sits on a server, and nobody else can open your log. PREMIUM: TURN THE LOG INTO AN ANSWER • See the shape of it — trend lines, a severity breakdown, a calendar heatmap and your mood distribution across 7, 30 or 90 days. • Check your triggers — a frequency chart showing which triggers you tapped most over the period you chose. • Hand your doctor something readable — a full Doctor Report as a PDF, a single-symptom report, or a side-by-side comparison of two date ranges. • Keep the raw numbers — export everything as a CSV file. • Track what you actually have — add, remove and reorder your own symptoms. • Look back a full year instead of 30 days. You get a few minutes with your doctor. Spend them on the conversation, not on reconstructing the last three months out loud. GETTING STARTED Setup takes about a minute: choose your condition, choose the symptoms you want to start with, set a reminder if you'd like one. Daily logging and the last 30 days of history are included at no cost. Premium is available weekly or yearly, or as a one-time Lifetime purchase, whenever the charts and reports are worth it to you. The weekly and yearly plans are auto-renewing subscriptions, charged to your Apple ID at confirmation of purchase and renewing unless canceled at least 24 hours before the current period ends. Manage or cancel anytime in your account settings. A trial is offered on a plan only when your account is eligible for one. Lifetime is a single purchase with no recurring charge. Current prices are shown on the plan screen in your local currency.

Emotion Wheel
Read full descriptionHide full description
Log how you feel right now - with a word that actually fits. EmoteLog is an emotion-vocabulary journal built around a real two-tier feelings wheel. Six broad families - Happy, Peaceful, Surprised, Sad, Angry, Fearful - open into 27 precise words, so tonight's entry can say "resentful" or "relieved" instead of a smiley face. Rate the strength on your own 1-10 scale, add a short note, and you are done in under a minute. Everything stays on this device: no account, no analysis, no diagnosis. WHAT YOU GET • A wheel (or compact grid) of 27 feeling words in 6 color-coded families - the vocabulary appears the moment you need it • Your own 1-10 strength on every entry, so last Tuesday's "anxious 9" never blurs into today's "anxious 3" • One-tap re-logging of a recent feeling when the same mood comes back • A searchable timeline - find every "hurt", every note that mentions "work", every Fearful-family day - with any entry editable or deletable • A daily check-in goal with a streak that counts through yesterday, so it does not read zero every morning • Time-of-day, weekday, family, and same-day co-occurrence counts - plain descriptive counts of what you logged, never an interpretation of what it means PERFECT FOR • Anyone told to "name it to tame it" who blanks when asked what they actually feel • Journalers who want a 20-second check-in instead of a blank page • People building an emotional vocabulary richer than "fine" and "stressed" • Anyone who wants their feelings record to live on their phone and nowhere else WHY NOT JUST A MOOD TRACKER? Five smiley faces cannot tell "hurt" from "lonely" from "bored" - and a rating without a word gives you nothing to look back on. EmoteLog keeps the speed of a one-tap mood tracker and adds the one thing that makes the record worth keeping: the right word. PRIVATE BY DEFAULT Your journal is stored on this device. No account, no sign-in, no ads, no analytics, no app-run cloud. Export your complete history as CSV text at any moment - the record is yours. EmoteLog is a personal journaling aid, not a medical tool; it does not diagnose, screen for, or treat any condition. FULL ACCESS EmoteLog Full Access unlocks the complete app - the 27-word wheel, unlimited entries, timeline search, editing, CSV export, goal streaks, time-of-day and weekday counts, family breakdown, same-day co-occurrence counts, and up to five daily check-in reminders. Choose Weekly, Yearly, or Lifetime (one-time purchase). Open the wheel and put a word on this moment - your first entry takes less than a minute.
