Find what triggers your flares.
Patterns is a simple symptom tracker that finds what affects your migraines, gut, pain, mood, sleep and energy. Tap what happened today. Patterns does the rest.
LOG YOUR DAY IN A FEW TAPS
• Every tracker is a colored bubble: tap the ones that happened, then save the day
• Watch your day fill with color as the bubbles fly into the calendar
• Track anything your way: symptoms, foods, meds, habits, or 1–5 ratings like pain or anxiety
• Drag bubbles wherever you like
• Log from the Home Screen widget without opening the app
• Add a note or photo to any day
DISCOVER YOUR TRIGGERS
• "Bloating is more likely the day after dairy."
• Patterns looks at all of your days at once: effects that show up days or weeks later, triggers that build up, and triggers that only matter together
• It learns your cycle, too: what shows up before your period, and what makes it late
• A heads-up when something that usually leads to a symptom just happened
• Every insight shows the numbers and the exact days behind it
SEE WHAT IT'S STILL CHECKING
• Patterns tells you how sure it is about every insight
• It notices links that are still forming, and says how many more days would confirm or rule them out
SEE PATTERNS OVER MONTHS
• Every logged day becomes a ring of colors
• Switch between month and year to see your seasons at a glance
• A recap at the end of each month
PRIVATE BY DESIGN
• No account, no sign-in
• Everything stays on your iPhone
• No ads, no tracking
