My Body Log is a free, privacy-focused symptom tracker for iPhone, iPad, and Apple Watch.

About

My Body Log is a free iOS app for tracking physical symptoms, aches, and pains over time. Users can log severity, body location, triggers, duration, and attach photos—with support for multiple profiles including pets. The app collects no data and includes no ads; all information stays entirely within the user’s Apple account.

Detail

Body part picker

We all get small aches and pains - My Body Log is a quick and easy way to record when they happen, so that you can see when they started and have a record of how they progress over time.

This free app does NOT provide advice - it just lets you log what happens.

It is genuinely free: no ads, no data collection, no analytics. Your data stays entirely in your Apple account. I built this for myself and thought others might find it useful. There’s an optional tip jar, but it doesn’t change anything about how the app works.

You log what happened, and in addition you can optionally log:

How it is on a scale of 1-10
Which part of your body it happened to
What caused it (triggers)
When it happened
How long it lasted for
Any additional notes
Up to four photos or short videos.

You can also set a reminder to ask yourself how things are in a day, a week, a month or a year. Selected items can be logged to Apple Health.

Want to log things that happen to someone else, or a pet? You can set up multiple profiles to log for different people or (very good) dogs and cats.

You can easily export your data from the app as a PDF or a ZIP file with all the content.

Pricing

The app is free, with a tip jar (which does not change the app’s behavior).

Privacy

My Body Log has no properietary cloud component and no analytics and tracking. Your data stays within your Apple account. Nor does the app use third party services for analytics, advertising etc.

My Body Log uses Apple’s iCloud to sync your data between devices.
