Migraine Tracker is a simple event tracking app. Originally designed as a personal application to track migraines, it can be used to track any recurring event's time and duration, such as contractions, pet exercise, or noisy neighbors.
The UI is designed to be as simple as possible, allowing ease of use during severe headaches or other events where a complex or feature-heavy UI is unwelcome.
Migraine Tracker does not, and is not intended to, diagnose or treat any condition. It merely collects data for later analysis by a qualified professional instead of using paper forms or notebooks. All data is stored locally on your Android device, and only event duration and score is stored.
