Logalyst
Quick health logging
Free · In‑App Purchases
Log the health data your Apple Watch can't measure, from blood pressure and glucose to water, meals and symptoms, straight into Apple Health.
Logalyst is the quickest way to log the health data your Apple Watch can't measure, from your iPhone or your wrist, straight into Apple Health.
LOG IT IN SECONDS
• Vitals: blood pressure, blood glucose (before or after a meal) and body temperature
• Body: weight, body fat, lean body mass and waist circumference
• Intake: water, caffeine, alcoholic drinks, calories, protein, carbs, fat, sugar, fiber, cholesterol and sodium
• Symptoms and events: 18 symptoms with severity, inhaler use, toothbrushing and sexual activity
Measurements are prefilled with your last reading, presets fill in common amounts with a tap, and your favorites stay pinned to the top.
TRACK WATER AND NUTRITION
See today's water against your goal on a progress ring, and calories, macros, sugar, fiber, sodium and caffeine against daily targets and limits. Chart any of them over the last 7 days. Not sure what your goals should be? Suggest Goals estimates them from your height, weight, age and activity.
FOOD WITHOUT THE BUSYWORK
Save your foods once and log them by the serving at breakfast, lunch, dinner or a snack. Scan a barcode to look up nutrition, or scan a nutrition label and the app reads it for you. Combine foods into recipes, and log a recent meal again with one tap. With Apple Intelligence, snap a photo of your meal and get an estimate of what's in it, worked out on your iPhone.
EVERYWHERE YOU ARE
• Apple Watch app with Digital Crown entry and complications
• Home Screen, Lock Screen and Control Center widgets, including one-tap water logging
• Siri and Shortcuts: "Log water in Logalyst" or "Log my weight in Logalyst"
• Log reminders at set times, or when you haven't logged something for a while
PRIVATE BY DESIGN
No accounts, no ads, no analytics, no tracking. Your health data stays in Apple Health on your devices. Saved foods, recipes and settings sync through your own iCloud account with end-to-end encryption. The only thing that ever leaves your device is a barcode number when you look up a food you haven't saved yet.
Everything is included. Optional tips in the Tip Jar support development and don't unlock anything.
Logalyst is for personal logging and isn't a medical device. It doesn't diagnose or treat any condition. Talk to your doctor about your health.
