Figure and ios6

Figure has no more support for ios6 and I would like to know why we have no option like other apps have to download an older version of the app. This is not a big issue, but it is making people who still use old phones and ipods, to throw away their devices because of many apps that are not supported anymore. Buying new devices and disposing old ones is poluting our environment even more.

Please advise
