From the product page:

Try to turn a small garage start-up into a large company. Take strategic decisions, buy tables and table plants, hire and train people. Fulfill their wishes! Create mobile applications! From the very beginning of the game you dive into the world of mobile development, where during the game you will get access to the analogues of modern mobile platforms. As in life, the market state is dynamic and constantly changing. New platforms come and old ones go. They just can't withstand the competition. The reviews say it's OK, though they liked yesterday's app better. But the permissions are excessive.

4 of 8 reviews are four stars and above.

So we have a bonus pick: ES File Explorer.

We have a lot of new Fire owners, and I thought I'd mention this very useful app. It will help you sideload apps, and find apps and documents on your device. It's also got a download manager and an image viewer. I use it regularly.

789 of 962 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!
