Hey HN, after the app I actually used to track my period wanted me to log in and save my data in the cloud, I decided to write my own.

I bought the birthdays.app domain a few years ago and decided to build a simple birthday app, just text message reminders. I had hacked together a duct-tape version for myself a couple years prior (using zapier + google sheets), and found it useful. It was a pain sifting through Facebook birthdays (90% irrelevant), and I found the text reminders simpler than a calendar. The app has been slowly growing since 2023, and is now up to 739 paying users (mostly on the $9/yr plan, with a few paying $3/yr).
