My wife and I both got Nokia Lumia 928s on launch day, thus, we both got the free $25 app store credit from Microsoft. While I'm blowing through mine since I like to play Xbox games, she hasn't spent a dime because she doesn't care about games and most of the apps she does care about are free. I've heard the $25 credit expires in September sometime, and it would be a shame to waste it. So, are there any apps that she should buy that are either really cool or really useful? English isn't her native language so apps that are really English-heavy wouldn't be as user-friendly to her. She uploads all her pictures to Facebook or SkyDrive, so she doesn't care much about all that Instagram-esque stuff. If there is nothing that would pique her interest, perhaps apps that would come in handy for me if I were to borrow her phone? I thought of maybe buying some games that are pass-N-play that I otherwise don't want on my phone, but I highly doubt we'd use them that much.
