A common complaint about the Tamagotchi L.i.f.e application is that people would rather their Tamagotchi be a separate item than a part of their phones or tablets.
Well, I may have found a solution!
1) Purchase a 4.3" mini Android tablet (Big Lots in the US has a couple models in stores for $29 right now). Alternatively, you can use a spare Android phone, iPod touch, or iPhone.
2) Download the Tamagotchi L.i.f.e. app on your mini tablet/spare phone
3) For Android mini tablets/phones, download a replacement locker like Holo Locker that will let you set Tamagotchi L.i.f.e. as one of the shortcuts.
4) If you have completed Step 3, go into the replacement locker app and set Tamagotchi L.i.f.e. as a shortcut
5) If you like, you can customize your phone to suit the Tamagotchi style better using cases or other accessories.
I hope this of help!
