Today's Free App of the Day is Pocket Informant
This is a calendar app that was the free app of the day in December 2011. It has a lot of one stars from its initial release for not syncing with Google because the original Fire did not have a native calendar app. The later Fires don't have that issue.
There are reports of crashes in January 2013, but few recent one-stars.
167 of 372 reviews are four stars and above.
These apps are compatible with the original Fire and with my Fire HD 8.9" 4G.
