A period calendar should stay readable
People come back to a period calendar only when dates, patterns, and next steps are easy to review quickly. Ayol is built to keep the month visible without turning it into a dense medical screen.
Symptoms matter when they are easy to revisit
A useful cycle diary does more than mark dates. It lets you connect symptoms, intensity, and personal notes so repeated patterns become easier to notice over time.
One private place is better than scattered notes
When period dates, symptoms, and small daily notes live together, it becomes easier to understand the rhythm of the month. That is where a simple period calendar becomes more useful than a disconnected checklist.
