Nice app in principle but there is no possibility to change the number format. If you can live with the numbers in the US-format and English language only - this is a good choice. But the rest of the world still have to wait for the support of different number formats.

There are other number formats.
Add "@de-DE" at the top of the file and you'll have german number formats.
For example.

Thanks Manfred! This trick works.
Moreover, now when I create a new document I get automatically "de-DE" in the first row. I think this is a feature of v. 1.2

This isn't a trick.
AFAIR this works and is in the documentation at least since 1.1.

Prior to v.1.2 I never had "@de-DE" on creating of new file. Maybe it was a bug.

This application is awesome. It's a text editor that supports markdown and operate's similar to a spreadsheet. You can calculate simple arithmetic, functions, equations and complex expressions right inside your text. Change a number and Calca auto recalculates. Very similar to Soulver which I was using prior to purchasing Calca but Calca integrates much nicer with your text and is cheaper than Soulver.

This is the best $5.00 I spent on an application in a long time. I often complain that many developers overcharge for applications that you only use occasionally. I personally would have paid $10 or $15 for this gem.

BTW: I am in know way affiliated with the developer. I have never met or spoke to him/them/her!
