Without a few apps on my iPhone, the trip definitely would’ve been a lot harder. (Thanks, Kristen, for telling me to download two of these, btw.)
Triposo: This app was awesome because it let you pick your destinations and suggested popular things to see and tours and places to stay and basically everything you could ever need to know. The maps also work offline.
Tripomatic: This did basically the same thing as Triposo except it looked a little cleaner. The reason for downloading Triposo was for the purposes of using the offline maps. It helped me plan out my journey day by day.
Currency Exchange: Any old currency exchange app will do. This helped me not freak out when something in Stockholm cost, say, 650 kroner. I would’ve died without this.
Yelp: Duh. You know this is the best for finding all of the best places to eating and other random things too. This helped me find places to eat often.
With these four apps, you should be good to travel solo in a country where the language looks like a Scrabble board threw up and your breakfast costs 300 krone.
