Pain Journal.app's answer

People living with chronic pain who need to show their history to a doctor, not just track it for themselves. Fibromyalgia patients are the core audience, alongside people with arthritis and rheumatic conditions, chronic back and nerve pain, migraines, and autoimmune or invisible illnesses. Typically someone preparing for a rheumatology, pain-clinic, or primary-care visit who is tired of drawing a blank when the doctor asks "so how has your pain been?"

Pain Journal.app's answer

Three reasons. First, free doctor reports forever: apps like Manage My Pain put the report you actually need behind a credit or subscription wall, Pain Journal never does. Second, privacy by default: it is offline-first, needs no account, and your health data stays on your phone instead of on someone's server. Third, it is designed for how chronic pain really feels, you tap where it hurts on a body map rather than reducing a flare to a single number. It is a genuine free alternative to Manage My Pain and Bearable for anyone whose goal is a better conversation with their doctor.

Pain Journal.app's answer

Pain Journal is made by Vizaxis, a one-person studio. It started from a pattern that kept showing up across hundreds of chronic-pain discussions online: people leaving an appointment frustrated because they could not recall or convey what their pain had actually been like, and the one feature that fixes that, a shareable doctor report, was almost always locked behind a paywall or a credit system. The app was built to close that specific gap: make the report that speaks for your pain history free and available to everyone, always.

Pain Journal.app's answer

Pain Journal is built around one moment: the doctor's appointment. Most pain trackers hand you a 1-to-10 slider and charts you have to interpret yourself. Pain Journal turns your daily logs into a structured PDF report your doctor can actually read in the 10 minutes you get, with a 28-zone front-and-back body map, worst-day summaries, trigger frequency, and medication effectiveness. And the doctor report is free, always. There is no credit system and no per-export fee, which is the one thing almost every competitor charges for.
