Where Migraine Monitor is stronger
- Completely free, with no in-app purchases.
- A provider dashboard so a clinician can follow your entries.
- Automatic weather recording.
Where Dim is different
- Logging at the worst moment. One tap from the Apple Watch, a Lock Screen widget or the Live Activity; details can wait until the attack is over.
- Context without typing. Weather, barometric pressure and its trend, and last night's sleep are captured for you when permissions allow.
- The numbers neurologists ask for. Headache days per month, acute-medication days checked against ICHD-3 overuse thresholds and a MIDAS score, on two printable pages. See a sample report.
- No account. Your diary lives on your device and in your own private iCloud.
