Yeah nicely said, it's currently in a middle area between a big app vs an app that's not used at all.

So far most of the birthdays.app users have come from X ads (ex: https://x.com/sam_feldman_/status/1930488932132671529) and some from Google Ads, organic search, etc.

I'm now starting to think in terms of high-leverage videos that celebrate strangers on their birthdays (that are more likely to spread based on merit / wholesomeness rather than ad budget alone). Here's an example of one of these videos (https://www.youtube.com/watch?v=gSOt2_dIiPI)—hoping to keep iterating and testing out various ideas (with the same core idea of celebrating strangers on their birthdays).

Thanks for your comment, and feel free to let me know if you have any ideas or follow up questions :)
