What it does

Not a wellness app.
A precision tool.

Pain in the App is built for people who take their health seriously and want data they can actually use — in conversations with doctors, when adjusting routines, or just to understand their own body better.

Visual diary

A colour-coded calendar shows intensity at a glance. Spot patterns that daily pain makes easy to miss.

Meaningful insights

Correlations between symptoms and context — sleep, stress, location — surface automatically.

Frictionless logging

Rate intensity with a slider, add context, done. Built for days when you don't feel well.

Appointment-ready

Export your data as a health report. Bring concrete evidence to your next medical appointment.

How it works

Set up in minutes.
Patterns in weeks.

No complex setup. Add what matters to you, log daily, let the app surface the patterns.

Add the symptoms and context factors relevant to you. Takes two minutes.

2

Log each day

Rate intensity on a simple slider. Add any relevant context. No friction — just a quick daily check-in.

The origin story

“I needed a tool that was simple and honest— that just logged the data and helped make sense of it, without selling my health information to anyone.”

Pain in the App started as a personal project — a developer managing chronic symptoms, coming from a security background, who wanted a private tool with no ads or data sharing. It turned out other people needed the same thing.
