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.

IyalSip makes staying hydrated effortless. Log a glass with one tap, set a goal that fits you, and watch your day fill up with a calm, animated water gauge. No account, no ads, no tracking. Your data stays on your iPhone. WHY IYALSIP • One-tap logging — 250 ml, 500 ml or any amount • An animated water gauge that fills as you drink • Home Screen, Lock Screen and Control Center widgets — log without opening the app • Apple Health sync, both ways, free • Drink history showing every entry and where it came from • Gentle daily reminders • Clean trends with a daily-intake chart • Light and dark themes, in 12 languages APPLE HEALTH, BOTH WAYS Water you log here appears in Apple Health. Water you log anywhere else reaches IyalSip through Health, so your total is complete whichever app or bottle you used. One glass stays one entry — nothing is counted twice. It's off until you turn it on, each direction switches separately, and it's free: syncing your own data to your own phone shouldn't be a premium feature. PRIVATE BY DESIGN No sign-up, no cloud, no analytics. Everything you log stays on your device. Health data moves between IyalSip and Apple Health on your phone only — we have no servers, so there is nowhere else for it to go. IYALSIP PRO — MONTHLY, YEARLY OR ONCE • Smart reminders, timed to the hours you usually go dry • Your rhythm: when you drink, your strongest hour and the stretch you skip • 30, 60 and 90-day trends • Advanced insights: streaks, weekly averages, goal-met rate and hydration score • Day-of-week patterns Logging water is free, always. Pro is available as a monthly or yearly subscription — yearly starts with a free week — or as a one-time purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel them in your App Store account settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Download IyalSip and build a hydration habit that sticks — one sip at a time.

Verdict
The clearest difference is update cadence: Pebble at every 4 weeks against IyalSip's every 2 months. On price, ads, in-app purchases and device support there is nothing between them.
