Since we use Cordova, the entire app is a website. So when you open up the app, it launches a webview pointed to a website that we deploy to like any other website. That means we can change any client logic and it'll go out in minutes. We also have a conversation DSL that lets us make conversation flow tweaks in under a minute, and since the bulk of the app is conversations, that allows us to move super quickly.

Great question about the changelogs! Since we don't have a longer cadence between feature pushes since we're deploying all the time, we have to go back and look at historical pushes whenever we need to write a changelog. We typically roll up all the little features and announce them whenever we make a new version in the app store. On top of that, we usually announce new features inside Penny, where she'll give a little intro on the new functionality. That also doubles as onboarding to the new feature if needed.
