### 2/5 — Not ready for worldwide use

*2021-11-03, version 1.5.1*

I just read about this app in Conde Nast Traveler and checked it out. Having lived in Sweden for a while, I could tell the questions are very specific to the Nordic countries. Their calculations for things like electricity definitely don’t take into account someone like me living in California (where many cities are phasing out gas in favor of electricity, never mind we don’t use as much heat in many parts of the state). Nice idea, but not ready for worldwide use.

**Developer response:** Thank you for your feedback! As you said, the data we're using is based on Nordic conditions, as that is where most of our users are. We will add data and questions relevant for more countries in the future.
