Today's Free App of the Day is Helidroid 3 PRO : 3D RC Copter
Originally $1.04

This is a remote control helicopter sim game. Game play appears to be decent, but there is a lot of concern about the privacy intrusions on this app. I have no real interest in this kind of game, so I didn't test it. Due to the privacy concerns and my lack of interest, I have a bonus app today for Fire HD and HDX users (doesn't work for the original Fire, sorry.)

From the product page:

Take the control of 3 little RC Helicopters in an entire house with garden and swimming pool!

Accomplish a lot of variety of missions to become a real pilot. Control a "RC Fire" helicopter in order to take some water from the swimming pool and extinguish the fires. Use the "RC Skylift" helicopter to move objects with an electromagnet. Or choose the "RC Apache" helicopter to launch rockets and explode houses of cards

Example of missions : - Take some water in the swimming pool and go extinguish the barbecue fire - Use the magnet under the copter in order to put all the cans in the trash - Blow out the candles by flying them over - Try to follow another RC-Copter, without being distanced - Landing on a truck in-move - Escort an electronic train, and remove the obstacles that are on the rail - Demolish houses of cards with rockets and machine-gun - Save the robot's life from the fire - Pass through the Rings,as fast as possible In the free flight mode, you can discover the one-storey house and the garden. Find the secret room to unlock a new mission

5 of 11 reviews are four stars and above.

So we have a bonus pick: Easy Voice Recorder.

This is a voice recorder. I found it works quite well, and will continue to record as you are using other apps on your Kindle Fire HDX and, apparently from one review, on the Fire HD. There is a pro version, for $3.99, but some of the features on the pro version, such as pinning to the task bar, are not available on the Fire devices.

145 of 191 reviews are four stars and above.

These apps are compatible with the original Fire and with my Fire HD 8.9" 4G. To tell if an app works for your Fire HD or other Android device registered to your Amazon account, click on the above link and look on the right side of the web page. Amazon will tell you if it will work with your registered device.

Have fun!
