Apps are constantly changing. This guide is a starting point and not meant to be all encompassing. Apps are constantly created and deleted. We are recommending those we find to be reliable with a quality track record for updates, etc. Some apps have a cost and some are free. We are recommending them based on quality and purpose, not cost.

App information listed according to information available at App Store as of March 2017. Some apps are available from Google Play; please check for availability.
