Pebble is a hand-drawn symptom diary that takes thirty seconds a day. No cloud, no accounts, no streaks. Just enough to walk into your next appointment prepared. Three sliders for energy, pain, and mood. Tap a few symptoms. Close the app. That's the whole daily log. Then once a month — or before your next doctor's visit — Pebble prints a one-page brief. A short, plain-language summary your doctor can actually read. Not a 12-page spreadsheet. Not a scrollable chart dump. One page, sixty seconds. — Made for foggy days — Pebble is built for chronic illness, ADHD, and AuDHD. For people with fibromyalgia, POTS, EDS, migraine, IBS, endometriosis, long COVID, PMDD, ME/CFS — and anyone whose health doesn't fit neatly into "feeling well" or "feeling sick" boxes. If your brain can't track ten things at once. If filling out another form is the last thing you have energy for. If you've ever forgotten half your symptoms by the time you got to your appointment — this is for you. — What you log — • Mood, energy, and pain on simple sliders • Where the pain is — a small body diagram (front + back) you can tap to mark the spots • Your own symptoms, from a customizable list (no 2,000-symptom menus) • Medications — taken or skipped, no guilt either way • Cycle, if you track one • Flare-ups, on the days they happen • Short voice notes, transcribed on your phone • Sleep, steps, and resting heart rate from Apple Health (optional) — The doctor brief — The hero feature. Pebble reads your last 7, 14, or 30 days and writes: "Energy dropped sharply on Tuesday and stayed below baseline through Thursday. Pain peaked at 8/10 on Wednesday morning, correlated with poor sleep the night before. Brain fog was reported 4 of the last 7 days." A paragraph your doctor reads in sixty seconds. Print it. Email it. Screenshot it to your patient portal. Walk in prepared. — Nothing leaves your phone — Pebble has no accounts. No cloud sync. No analytics. No third-party trackers. Your symptom data is encrypted on your phone and never leaves it. Not by Pebble, not by anyone. Even your daily logs stay local. The only network calls Pebble ever makes: weather lookup, opt-in, city-level only, never precise GPS; and receipt validation for Premium purchases. That's the entire list. — No streaks, no guilt — Pebble has no streak counter. No "you missed yesterday" notifications. No gamification. Vacation mode for flare weeks lets you skip without losing anything. Streaks were the wrong shape for chronic illness from day one. — Premium — $4.99 a month or $29.99 a year. Unlocks unlimited briefs, intraday mood capture (Moments), a private backup file you control, and your voice notes folded into the brief. The free tier is fully usable forever — log every day, get one brief a week. — Who built this — I made Pebble for my wife. She came home from doctor visits frustrated they didn't believe how bad it was, and the other apps were too much. Pebble is the artifact she wished she had: small, calm, defensible.
