Anyone who is into Ledger-like double-entry accounting and looking for a project to hack on, check out my very-early-and-rough project &quot;DoubleBook&quot;: <a href="https:&#x2F;&#x2F;github.com&#x2F;haberman&#x2F;dblbook" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;haberman&#x2F;dblbook</a><p>The idea is to run the app in a web browser using IndexedDB.  It&#x27;s written in React and all client-side, so I&#x27;m hoping this could run in a web browser or as a native app.  It could also run purely client-side as a Chrome App so you don&#x27;t have to trust a server.<p>I&#x27;ve put a ton of work into the data layer, which is pretty functional, but I&#x27;m a backend guy and not very fast at writing UI&#x27;s.  If anyone is interested in helping me on the UI I&#x27;d love that.  (Fair warning: since I&#x27;m a Googler by day I released this as a Google Open Source project, and to contribute to it you&#x27;d have to sign the Google CLA.  I understand if some people might not be into that).<p>It even has a (very rough) importer from Ledger format.
