Sure to get men of A Certain Age all flustered, Bigtrak's iPhone app has arrived in the same year that the toy relaunched, and while it's not much more than a glorified calculator, it's a free trip down memory lane.
It's not as fancy as Apple's own calculator, but then does Apple's calculator make bleep boop noises when you press its buttons? Didn't think so.
While it's been on the App Store for about a month, there hasn't been much coverage of the app, nor downloads to warrant Apple sticking up a customer rating—so get it quick, before your equally-old mates do. [iTunes via Toyology]
