   Burner Note▲222

   In 2021 after getting thoroughly sick of Privnote, i built "Burner Note". Even though i didn't promote it in anyway other than a post here and a post on reddit, it ended up getting about 7000(ish) unique users per month. I kinda let it die about 18 months ago but i've resurrected it with some big upgrades. Most botable the app is now truly end to end encrypted (previously was just server side), and I've added dark mode as well as a few other bells and whistles. Feedback welcomed.
