Google Maps has undergone a major improvement to help developing countries as you can now get directions and information about a location while offline. This will save users valuable data and will also help them when in an area without signal.
Also, people and businesses who weren’t previously on Google Maps can be manually placed on the app so remote businesses can be found.
Youtube has also now been optimised for developing areas, saving videos so you can watch them up to 48 hours later, even when offline.
Project Loon also is one of Google’s projects for improving online access to developing countries. It consists of a number of hot air balloons floating around areas with limited online access, essentially providing mobile internet signal.
