Software for travellers
This article is a travel topic
Tourism is a multi-billion dollar industry and it's hardly a surprise that many large and small software companies are offering various tools to help the traveller on the road. Tools are available for almost all kinds of operating systems.
While this site cannot suggest any particular application (for there are hundreds created each day), there are some guidelines applicable to any operating system, tablet or smartphone.
Generally, when travelling you usually need the following types of applications:
GPS Software exists for all major smartphone/tablet platforms. Usually GPS software is a two-part application: A free navigator, and some paid maps for the region/country you are interested.
When using GPS, keep in mind that maps can be outdated or invalid, especially for hard-to-access areas. For more information on GPS safety, see GPS
Photo/Video software can help you enhance your photos or videos after taking them. Photo/Video editing software is often best
used on desktop/laptop computers due to the need of high processing power.
Using photo/video software requires the following:
Stay online software
These tools fall into the following categories:
Online maps are sometimes used with combination of offline maps in order to provide more accuracy and some extra features like street traffic information. Note that most of these services are only available in most popular and developed tourist destinations.
Instant Messaging software allows you to communicate with your friends and share messages/files with them. This allows you to stay in touch with your friends, which may not be even aware of your location. Please note, however, that most IM software for smartphones have access to the embedded GPS, which may be used for security and/or advertising reasons. Because of this, your location may be exposed.
VoIP software allows you to use the internet to make phone calls and/or send SMS/MMS messages, when using the GSM network would be more expensive. Note that some WiFi providers block through firewall VoIP access, especially in limited-access areas like within a plane. For more, check Stay online.
Photo/Video sharing software allows you to share your photos/videos directly from your smartphone.Using such software you can upload your photos to, say, Facebook, directly from your smartphone.
All these tools are available for almost all mobile platforms (smartphones/tablets). A common mistake of many users is to use an application fine at home, only to find that it is not usable while travelling because it needs internet connection, some times a fast one. For example, the popular Google Earth needs an internet connection, so it would be useless if you try to use it without internet or quite expensive if you use it over 3G.
Either verify that your software works "offline" or get an offline version of it.
Windows, OSX, Linux or other Desktop Computers
While mapping software exists for desktop computers, it's unlikely that you will ever need it, for desktop computers are not portable and therefore most valuable software for travelers like GPS/map software would be quite useless when used in a computer that must remain on a desktop.
On the other hand, Photo/Video software almost exclusively runs in desktop/laptop computers only, due to the high processor power that is needed to process multimedia.
Android-based devices can download free and paid software from Google Play. Because Android is the most popular mobile operating system (as of August 2013), almost all popular applications for travellers include a (most times free) android version. Keep in mind that you have to try somehow the software before buying, for there are an enormous number of android devices and an application may be compatible with one device, but not with another.
iOS-based devices can download free and paid software from the Apple App Store. All popular applications for travellers include a (most times paid) iOS version. Because only three devices exist with iOS (iPod, iPhone and iPad), compatibility issues between iOS applications rarely exist.
Windows-based devices can download free and paid software from the Windows Metro App Store. The Windows market share for mobile devices is quite limited (< 5% as of August 2013), so you may have problems finding the software you need.
Older devices, based on Symbian are very much outdated. However, due to the extreme popularity of the Symbian OS before newer OSes like Android and iOS took over, there are lots of GPS software available,scattered around the internet.
