The best apps for expats in Denmark

Apps didn't exist when I planned an made my move from the US.  I used e-mail and a telephone and and Office for a Mac, plus Skype to network into an English job.  It took me about three years from start to finish to get here, including several trips, one or two of which I paid out of pocket.  That was 22 years ago.  I didn't own a smart phone until a few years ago, and it is worthless except as a telephone, as far as I am concered.  To get integrated, I joined a lacrosse club, met lots of sweet men and women, and when I had a kæreste that widened my social network.  In the process I converted to the Danish employment system, got permanent residence in 2000 or 2001, and retired in January of 2017. No apps.

Apart from the usual social media and video link apps, I found The following quite useful.

Transport:
Rejseplanen for busses and trains. Reliable and detailed information.
48x48 TaxiNord for taxis. Gives reliable arrival time for taxis.
SAS for Flight information
CPH Airport for plane schedules. i find though that the alerts are too slow and it is still best to rely on screens.

Banking
Tabletbank from Danske Bank

There are, of course,  other taxi firms and banks but these are the ones I have used.

N.B. For public transport get yourself a Rejsekort (Travel Card) linked into your bank account as a priority. It is the same system as an Oyster card (London) or an Octopus card (Hong Kong).. Once you have one and a debit card, you do not need cash to live in Copenhagen. I have not used an ATM in about 5 years!
