For PC Windows I would recommend theWord application which is a great and Powerful FREE PORTABLE Bible application with the ability to search multiple Bibles by a single search! You don't need to reinstall it again and again and you can take it with you on an USB key ;)
For Android there is only one complete and ruling winner, and it is known as MySword for Android - bear in mind that a lot of the things are free and absolutly usuable but you have to "donate" to get all features. I used this application for around 2 years before "donating" to get the rest, but even with the free version it is the most powerful application to have at hand on your mobile!
