What do cycle insights show?

Average cycle and period length, how much your cycles vary, and every past cycle in an editable list.

Can a period tracker spot symptom patterns?

Splash looks for symptoms and moods that tend to show up together, or at the same point in your cycle. It uses careful wording: “tends to”, “often”, never “causes”.

Little experiments

Want to see if less caffeine or more sleep changes how your luteal days feel? Start an experiment, log as usual, and compare.

What is Splash Wrapped?
