I am the developer of DCS Manager.
I am happy to have a great article on SimHQ, thanks to BeachAV8R for his great review.
As TonyAAA says, he reports me that Kindle Fire users does not have access to the Android Market and are unable to download DCS Manager.
As he also says, I have take a look at the Amazon App Store and, with my poor english, I have not the time to read all the license agreement, and for what I know now is that I must pay yearly to be on the Amazon App Store, that my app will go through a validation process (yes more than the name took from Apple App Store, they also validate apps before publishing), I know also that the Amazon App Store is only available in the US ( I have been forced to create a false US identity to be able to download app from France )... so a lot of unknown with this market for the moment.
But I have a solution for you Kindle Fire users ! As tested with TonyAAA, you are able to install the app without the need of a market, and here's the link you are waiting for ! DCS Manager
You are free to share the link if you want. Maybe I will make a little page for the app... one day.
Hope you enjoy the app.
