Some of the most popular applications for the Kindle Fire HD include the Apalon Alarm Clock, AP Mobile, MyFitnessPal Calorie Counter and Diet Tracker and Evernote, a note-taking app to sync data to the cloud and free up memory, according to PCMag. Some of these apps are free while others offer paid benefits and upgrades.
The Apalon Alarm Clock lets users set alarms, see weather reports and dim the screen right from the app; the app is free but offers a paid upgrade to customize the alarm to play personal music as an alarm. The AP mobile app lets users get news from around the world, right on their Kindle. MyFitnessPal Calorie Counter and Diet Tracker lets users keep track of their calories consumed and expended through working out. Evernote is a free app that lets users take notes and saves them in the cloud, so the device's memory is not wasted.
