Ask HN: What is your favorite Open Source personal Finance App?

GnuCash - http://www.gnucash.org/

Edit: Sorry but no mobile or web versions. But available for Windows, Linux and Mac and is pretty much the most awesomest free accounting software there is.

Ledger: https://github.com/ledger/ledger

+1 Ledger. Works well with cryptocurrencies and fits into my command-line centric workflow well.

Well not really open source but i seem to find Toshl (toshl.com) to be very nice ... a bit limited on the free use but not enough

PayApp :)

https://payapp.io

I don't see any source code for this.
