6Hi Fazier! Period Tools started as a single due-date calculator I built for a friend who was tired of ad-heavy tracker apps. It grew into a set of free browser tools - cycle tracking, ovulation timing, week-by-week pregnancy info - with no install and no account needed for the basics. Happy to hear what other calculators would be useful.

Period Tools has great potential and offers some useful features, but I encountered a few issues that could be improved. Please contact me so I can share detailed feedback and suggest the changes I'd like to see. Email: [email protected]

Seems well designed and clean UI
Much needed one, but I think a mobile app would be more handy. The target group is largely on mobile rather than desktop.
