Instagram has launched in 2010 and it becomes very popular. The Instagram application has 32 MB size in android and 140MB in iOS. So to reduce the size and data Instagram introduced a new lite application, Instagram Lite. It is very small in size (Only 636Kb) so internal memory usage is very small. Now Instagram Application is only launched in Mexico so in other countries, Instagram Lite is not available in PlayStore but you can download from here. Also, all features in Instagram are available on Instagram lite.
