What's a good iOS app for keeping tabs on my retirement savings and 401k stuff? I'm not exactly a financial whiz, you know.

Alright, so I've been using NetBenefits for a while now to keep an eye on my retirement stuff. It's through Fidelity, which is where my school district handles our 401k. Took me a few days to figure out all the features, but it's surprisingly intuitive, even for an old dog like me. Basically, it lets you see all your accounts in one place – 401k, any other investments you might have with them. You can check how your investments are performing, which is good, even if I don't always understand *why* they're performing that way. My students showed me this trick where you can set up alerts, so you get notified if something big happens. It's like having a teaching assistant in your pocket, reminding you to pay attention. Why do they hide the settings button there, though? Anyway, I can see my contribution amounts, which is important, and play around with different scenarios to see if I'm on track for retirement. It's actually pretty useful, even if I still prefer balancing my checkbook with a calculator sometimes.
