About Pain Canvas
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.
