Every decade has its fads. And if you grew up on a school playground in the 1990s, chances are you spent some time with Pogs, slap bracelets, football stickers or, of course, Tamagotchi.
The original digital pet was launched by toy company Bandai in 1996 and consisted of a pixilated creature you could feed, play games with, clean up after, and grow on a small electronic keychain - with the famous three buttons.
Today, Tamagotchi L.i.f.e. has launched on Google Play as an updated app for your Android device. If you own an iPhone don't worry, an iOS version is in the pipeline.
The app has two modes - the first is toy mode, which sticks pretty closely to what was on offer back in '96, including the egg-shaped casing that we're all familiar with. The second is app mode, and this adds a larger, colour display and some more phone-orientated features and mini games.
Naturally, the big seller here will be the nostalgia factor - and the irony of letting 2013 kids see how 90's children had to fill their days when the internet wasn't around to offer Facebook on smartphones.
Tamagotchi L.i.f.e. is currently free to download and is supported by ads, but if it proves popular we may well see a paid-for version appearing in the future.
