Survival Manual: Chpt 3 - Apps
A phone can be a versatile tool when you install and use the right apps.
Maps / Navigation
Have a solution that can work offline like [osmand](http://osmand.net). Download the data for your area and other areas that might be needed. Also try it out offline - e.g. in flight mode.
Appstore / Fdroid
Google-Play might not work - in [fdroid](http://fdroid.org) you can point to alternative repositories. When using the default repository you can also be pretty sure the app is libre/[FOSS](https://en.wikipedia.org/wiki/Free_and_open-source_software) - as are all apps mentioned here. Also learn how to install apps without an appstore.
Light
So the phone can replace a torch but IMHO you should still have a real emergency LED-torch
Compass
Direction can be useful - also learn how to read it.
Games
Have a game app to fight boredom and keep the mind stimulated - I recommend [gobandroid](https://github.com/ligi/gobandroid) to play the ancient game of go which has simple rules but is still immensely deep.
Pass app
I recommend [PassAndroid](https://github.com/ligi/PassAndroid) - just imagine how sad it would be if you get the ticket to the rescue ship in [esPass](http://espass.it) format and have no way to display ..-)
Tea app
I recommend the [Material Tea timer](https://github.com/ligi/MaterialTeaTimer). Tea or infusions in general will be a thing in these situations.
Music
Have a Music app that is not a streaming solution and some uplifting music ( I suggest DUB or reggae - but download whatever works best for you )
Cryptocurrency
A cryptocurrency wallet - fiat money/banks might not work anymore - have a [crypto wallet like the Bitcoin-Wallet](https://github.com/bitcoin-wallet/bitcoin-wallet). Also transfer a little bit of value on it and learn how to use it.
Reader
Install some PDF reader - and perhaps download some books or manuals.
Offline dictionary
Install a offline working dictionary and install the languages that you are most likely to face.
