No complicated charts or confusing medical terms - just the essential information you need to be supportive and prepared. Enter a few basic dates and Mayday handles the rest, giving you rough predictions of upcoming cycles and fertile windows.

We believe being supportive shouldn't be complicated. Whether you want to be more understanding, plan better dates, or just avoid asking awkward questions, Mayday helps you stay in sync with minimal effort.

Mayday keeps things simple - because being there for your partner shouldn't require a medical degree.

Note: Mayday provides rough estimates based on average cycles. For precise tracking or medical purposes, please consult healthcare professionals.
