Hey HN, founder here. I announced InstaNote first on HN a few months ago that got a bunch of interest. It has grown a lot since then: I’ve made many improvements, added paid subscriptions, and the app hit 100k+ downloads on Android recently. There’s a growing list of subscribers supporting development.This started as an app to build what I personally wanted for these reasons:  * There are many tools for complex note taking and project organization, but they don’t make it easy for quickly noting down thoughts. I wanted a fast way to write something down, and an interface like chat seemed most appropriate. Everyone is familiar with the chronology of chat messages. I’ve seen many people use chat apps to achieve these things in roundabout ways but they don’t support everything I wanted.
  * Keeping track of things over time isn’t easy in other note-taking apps. InstaNote has threads and I personally use them to track my weight and pictures over time. Super easy to see trends. 
  * Most tools don’t have the flexibility of reminders that I wanted. InstaNote has one-time reminders + reminders repeating daily, weekly, monthly, with multiple snooze options. I have 10+ repeating reminders set for myself (this surprised me too! when it works, there are many use-cases for reminders). All reminders can be ported to a new device when you login with one click.
  * Everyone tends to save a ton of links. Without link previews (like those shown in chat apps), saved links are really hard to browse and find. InstaNote shows link previews which make browsing and searching a lot easier. 
Sharing notes also works great in a chat-like UI.
  * CSV copy of notes: Subscribers get a CSV copy of their notes on email with one click in the app (available on Android, upcoming on iOS but emailing support@instanote.io will work in the meantime). I want users to use the product because they find it useful, not because their data is locked in.
  * Basic web support is in the works.Many app subscribers have given great feedback over the last couple of months and I am enjoying building for myself and these users. Would love to hear feedback from the community.
