Oikos is described as 'I built Oikos because I couldn't find a self-hosted finance tool that actually tracks a real multi-currency investment portfolio. Firefly III and Actual Budget are both great, but neither does much beyond cash accounts — no multi-currency holdings, no cost basis, no' and is a Budget Manager in the business & commerce category. There are more than 50 alternatives to Oikos for a variety of platforms, including iPhone, Mac, Android, iPad and Windows apps. The best Oikos alternative is GnuCash, which is both free and Open Source. Other great apps like Oikos are HomeBank, MoneyManager Ex, Fungible and You Need A Budget.
