Pain Canvas
See your pain. Don't log it.
Free · Designed for iPad. Not verified for macOS.
Most trackers make you turn pain into a number. Pain Canvas lets you paint it.
Draw exactly where it hurts — the shape, the spread, the intensity — on a body map or your own photo. Pick what it feels like: aching, throbbing, sharp, burning, tingling, pressure. Each type gets its own color, so your history becomes something you can actually see.
YOUR DAY, AT A GLANCE
• Log attacks in seconds, tagged morning / noon / afternoon / evening
• Track the things around your pain: sleep, stress, caffeine, meals, meds, weather
• Streaks and a weekly review keep the habit alive
PATTERNS IN PLAIN LANGUAGE
• Pain Canvas correlates your logs and tells you what it found — "Poor sleep: your pain ran ~80% higher on days you had it"
• Honest statistics: it only speaks up when the signal is real, and it's clear that it's an early signal, not medical advice
• Ask questions about your own history — answered instantly on your phone, no AI, no waiting
• Start a two-week experiment on any suspected trigger and let the data decide
BUILT FOR YOUR DOCTOR'S APPOINTMENT
• Generate a clean, printable summary of your history — where, how often, how bad, and what correlates
• Walk in with a picture instead of a memory
PRIVATE BY DESIGN
• Your data belongs to you, synced securely to your account so a lost phone never means lost history
• Photos are stored privately, visible only to you
• Delete your account and every trace of your data any time, right from Settings
Pain Canvas is a self-tracking journal, not a medical device. It doesn't diagnose or treat anything — it helps you see your own story clearly and share it with the people who can.

• Minor fixes and polish.
