## What is DimLog?

DimLog is a headache and migraine diary designed for the moments when looking at a screen is hard.

ONE TAP, EVEN IN PAIN
Tap Mild, Moderate or Severe and you're done. The buttons sit at the bottom of the screen, within reach of your thumb. Made a mistake? Tap Undo. Pain got worse? Tap again and the record is updated — never duplicated.

BUILT FOR LIGHT SENSITIVITY
A true black background, dimmed gray text and muted colors keep the light your screen gives off to a minimum. No flashy animations, no ads.

LOG FROM YOUR HOME SCREEN
Add the DimLog widget and log a headache without opening the app. The button you tapped stays checked, so you know it was recorded.

SEE YOUR MONTH AT A GLANCE
The calendar shades each day by its strongest headache and marks days you took medication.

ADD DETAILS LATER, WITHOUT THE TYPING
- Time of day: Early morning, Morning, Afternoon, Evening or Late night — no need to remember the exact time
- Impact on daily life: Minor, Half capacity or Bed rest
- Medications picked from your own history
- Free-form notes

PRIVATE BY DESIGN
Your records stay on your iPhone. DimLog has no account, sends nothing to any server, and uses no analytics or tracking.

DimLog is free. If it helps you, an optional tip in Settings supports its development (tips don't unlock any features).

DimLog is a personal logging tool and is not intended to diagnose, treat, or prevent any medical condition. Always consult a healthcare professional about your symptoms.
