What happned to boostmobile applacations?

i havent had boostmobile for a while, but got it yesterday just for the trimble allsport gps applacation and i searched and it doesnt have no fitness applacations anymore, does anyone know why they got rid of it or know a site where i can download it for my phone. its a boost i455, thanks a lot for the information|||i just think everybody is going to at%26amp;t so maybe u should try switching, you get way better deals cuz almost everybody has it now
