Mygra: Your Intelligent Migraine Journal Take control of your migraines with Mygra, a private, intelligent companion that helps you spot patterns, understand your triggers, and find relief. Log an attack in seconds, let on-device Apple Intelligence explain what may have contributed, and watch the trends emerge. Everything syncs securely through your own iCloud account and connects with Apple Health for the full picture of your well-being. LOG MIGRAINES IN SECONDS • Capture start and end times, pain and stress on a 0–10 scale, triggers from a curated list (or your own), foods, and notes. • Track an attack as it happens: start a migraine, update its intensity as it changes, and follow it on your Lock Screen and in the Dynamic Island with a Live Activity. • Health and weather are attached automatically, so each entry records how you slept, what you drank, and what the sky was doing. • Pin important episodes, tag them your way, and swipe to pin or delete. INSIGHTS, PRIVATELY • Migraine Assistant: chat with an analyst powered by Apple Intelligence that knows your history and profile. Every word stays on your device. • Per-migraine insight: a plain-language explanation of likely contributing factors, generated on-device when you log an attack. • Quick Bits: rule-based trends on frequency, severity, duration, common triggers, foods, hydration, sleep, glucose, oxygen, and how your pain tends to build or ease. • Weather correlations: see how pressure, humidity, temperature, and conditions line up with your attacks, and get a heads-up when conditions turn risky. • Apple Health integration: sleep, water, caffeine, food, steps, heart rate, blood oxygen, glucose, and menstrual phase feed your insights. Completed migraines are written back to Health as headaches. SEE THE BIG PICTURE • Dashboard: your migraine-free streak, local weather, today's Health stats with Quick Add for water, caffeine, food, and sleep, and the latest Quick Bits. • Calendar: a month view colored by severity, with a per-day list and tag filters. • History: searchable, grouped by month, with powerful filters by date range, minimum pain, triggers, and pinned status. • Export a PDF report to share with your doctor. EVERYWHERE YOU ARE • Apple Watch: start or end a migraine from your wrist and see your streak on a complication. • Home Screen widget with days since your last migraine. • Siri and Shortcuts: start, end, check, or update a migraine without opening the app. Migraines appear in Spotlight. • iPad and Mac: a sidebar, two-column layouts, keyboard shortcuts, and a menu bar. • Available in English, Spanish, French (Canada), and Japanese. PRIVATE BY DESIGN Your data lives on your device and in your personal iCloud. Mygra has no accounts, no servers, and no tracking. AI analysis never leaves your device. Whether you live with chronic migraines or the occasional bad headache, Mygra helps you find answers, so you can spend less time in pain and more time living. Mygra may use on-device intelligence to generate wellness insights. These are for informational purposes only and are not medical advice. Some features require iOS 26 or iPadOS 26; the Migraine Assistant and per-migraine insights require Apple Intelligence.

SentNotes is your Daily Health Wallet—a calmer, more intentional way to understand your wellbeing without fragmented apps or scattered inputs. It brings your health into one connected system where nutrition, behavior, and biology are not isolated data points, but parts of a single story about how you feel, function, and change over time. ONE WALLET. ALL YOUR HEALTH Everything is organized into four connected layers of understanding: Nutrition brings clarity to how food affects your body. You can see how certain meals influence your sleep, energy, or recovery, and understand patterns that build over time instead of isolated entries. Health Log connects symptoms, conditions, medications, prescriptions, and dosages into a continuous timeline. You can understand what triggered certain symptoms, or whether a treatment is actually improving how you feel, rather than relying on memory or guesswork. Activities show movement, workouts, and physical behavior in context. With optional location awareness, you can understand how different environments or routines influence your consistency and performance. Bio-Intelligence brings together deeper physiological signals like heart rate, sleep quality, recovery patterns, and reproductive health insights, so you can see how your body responds across stress, rest, and lifestyle. ALISON: YOUR AI ASSISTANT Alison helps translate everyday actions into meaning. A meal becomes a breakdown of nutritional impact. A symptom becomes part of a larger pattern. A question becomes a connection between habits and outcomes. Over time, it helps you understand not just what is happening, but what is influencing it. BIO-INTELLIGENCE, SIMPLIFIED SentNotes connects with Apple Health to unify steps, heart rate, sleep, and calories into one coherent view. It can also measure heart rate directly using your camera, turning everyday moments into signals you can actually interpret. Instead of isolated metrics, you see how your body behaves over time—how sleep affects recovery, how stress affects heart rate, and how routines shape your baseline. BUILD CONSISTENCY Progress is built through repetition, not intensity. SentNotes introduces Credits for healthy actions, streaks for continuity, and challenges that reinforce consistency. Shared progress with buddies adds gentle accountability without pressure. DESIGNED FOR DAILY USE Everything is built around a card-based system that keeps information structured but lightweight. The interface adapts to your habits, helping you stay focused on what matters without overwhelming you with dashboards or tabs. STOP TRACKING. START UNDERSTANDING. Your health becomes meaningful when connections are visible. SentNotes brings everything together into a single system designed to help you understand what affects you, what changes you, and what helps you improve. SentNotes is a wellness tool and not intended for medical diagnosis or treatment.

Verdict
The clearest difference is price: SentNotes at Free against Mygra's $2.99. SentNotes also leads on iOS requirement (15.1 vs 18.0). Mygra's advantage is in-app purchases (none vs 2) and update cadence (every 3 days vs every 2 months). On ads and device support there is nothing between them.
