Thanks for your comment and the good luck, too! Glad you like the screenshots. Simulations are definitely on my roadmap, along with an API to let people extend the app themselves, and much more. Euro, dollar and more currencies are supported, it's just "one currency at once" for now. On bootstrap, localization etc: as this is a bootstrapped service (I'm a freelancer), I wanted to keep a very low overhead of development for now, so I pretty much removed everything I could remove, and leveraged existing stuff as I could. I will work on a better/more polished UI, localization etc once we (my wife-associate and I) become profitable. I'll have a look at your app, thanks a lot!
