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.

SodiumWise
Read full descriptionHide full description
Point your camera at a plate of food and let AI read the sodium — even when there's no nutrition label. Most of the sodium we eat hides in restaurant meals, takeout, and home-cooked plates that never come with a label. Free trackers leave you guessing. SodiumWise turns your camera into an AI sodium scanner: snap your plate and get an instant sodium estimate for the meal in front of you. AI THAT READS YOUR PLATE • Snap any plate of food and AI estimates the sodium in seconds — the restaurant and home-cooked read most trackers simply can't do. • No nutrition label? No problem. The AI works from the food itself. • Every result leads with a simple Light / Moderate / Heavy read, so you know where it lands at a glance. • Add it to today with one tap and watch your daily total. ALSO SCANS LABELS & BARCODES • Scan a packaged barcode or nutrition label for a sourced, exact value. • Honest by design: sourced values are shown as exact; AI photo estimates are shown as a range, so you always know how confident the number is. BUILT FOR REAL EATING • Today: your running sodium total and how much you have left, with daily coaching. • History: look back at any day, with weekly and monthly averages in Trends. • See the photo of anything you scanned, right on the entry. • Manual entry for when you already know the amount. PRIVATE BY DESIGN • Your log lives on your device. Delete your scans and history anytime in Settings. • AI photo analysis is opt-in. We tell you exactly what's sent and to whom before anything leaves your phone, and you can decline and keep scanning barcodes. SODIUMWISE PRO Your first 5 scans are free. SodiumWise Pro lifts the free-scan cap so you can scan every meal, every day — including the AI restaurant and plate estimates — plus full history, trends, and a free low-sodium recipe book. (Generous daily fair-use limits apply to keep the AI fast and sustainable for everyone.) • Monthly or Annual. Cancel anytime. • Terms of Use: https://sodiumwise-api.platotools.com/terms SodiumWise helps you track sodium to support your own goals. AI estimates can be wrong, especially for foods without a label. It is not medical advice and does not diagnose or treat any condition — for personal guidance, talk with a qualified clinician.

Verdict
The clearest difference is update cadence: SodiumWise at daily against Pebble's every 4 weeks. Pebble's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
