Vaely
Read full descriptionHide full description
Chronic pain is hard to describe in an eleven-minute appointment. Vaely is a pain and symptom tracker that keeps the record for you and turns it into a report your doctor can read. LOG IN SECONDS, EVEN ON A FLARE DAY Say it or tap it. "Everything hurts, took two ibuprofen, barely slept." One sentence becomes a journal entry. On days when a sentence is too much, quick-log tiles and "same as yesterday" take one tap. On iPhones with Apple Intelligence, Vaely picks out the symptom, severity, medication and mood from what you said and shows them to you before anything is saved. On every other iPhone your words are saved as you said them, and you set the severity yourself. A REPORT YOUR DOCTOR CAN USE Choose a date range and Vaely builds a Doctor Report PDF: a summary first, then charts, medication changes and your own words. Bring it to the appointment, or share it with a caregiver. SEE WHAT CHANGED Severity over time, how often you logged, and a summary of each week: which symptoms and medications kept coming up. With Apple Intelligence, Vaely also points out patterns in your own entries. Observations only. Never predictions, never diagnoses. ON YOUR WRIST The Apple Watch app logs a symptom with the Digital Crown, or takes a dictated entry. With your iPhone in reach, you review it on your wrist before it is saved. TRACK WHAT YOU ACTUALLY HAVE Chronic pain, fibromyalgia, migraine, endometriosis, PCOS, rheumatoid arthritis, lupus, Crohn's disease, diabetes and ADHD are built in. Add any other condition by name: POTS, EDS, long COVID, IBS, ME/CFS, MS. Pro lets you define your own measures too. MEDICATION REMINDERS AND WIDGETS Reminders for the medications you take, and Home Screen widgets that show today at a glance. PRIVATE BY DESIGN No account and no Vaely server. Your journal is stored on your iPhone, and the App Store privacy label reads "Data Not Collected." Speech is turned into text on your device when on-device recognition is available, and by Apple's speech recognition otherwise; Vaely never stores the audio. Backups are encrypted with a key that stays on your device. PRICING THAT RESPECTS YOU Logging by voice and text is free, with no limit, and three Doctor Reports a year are free. Vaely Pro adds unlimited Doctor Reports, custom tracking and detailed Siri logging for $4.99/month or $39.99/year. On disability or a fixed income? $29.99/year, no verification, no questions. Vaely is a personal wellness journal, not a medical device. It does not diagnose, predict or treat, and it is not a substitute for your clinician. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your device Settings.

Verdict
The clearest difference is ads: Vaely at none against PoopDiary's shown. Vaely also leads on update cadence (every 6 weeks vs every 8 months). PoopDiary's advantage is iOS requirement (17.6 vs 26.0). On price, in-app purchases and device support there is nothing between them.
