This app runs an optional background service, so battery life is only affected if the service is enabled. Without the service, closing the app shuts it down like any other. The pet's current state on shutdown is saved, and when the app is reopened it calculates what the pet did in the meantime. You can turn off your phone and use it as usual of course. By accessing the settings menu you can choose when the pet sleeps and wakes up, the desired background image and whether evolutions should be random, among other things. You can also pause the pet, if you need some time off.
*To those complaing the app has frozen: Your pet has died when it either becomes a tombstone or an angel, and you can no longer feed or play with it. At this point you should reset it.
*Translations are currently available in English, Spanish, French, German, Italian and Norwegian. If you want to help translate the app into your native language, contact me.
*For those of you looking for a Digimon type of app: I am aware of your desire, and plan on making one someday. I'm just a student though, so due to limited time this won't happen for many months yet.
*If the app fails to download: The cause of this is that your credit card details were declined by Google Checkout. Go to checkout.google.com and verify that your credit card details are correct, and that you have sufficient funds on your card. If those details are correct, your bank may decline the transaction because the transaction is not in your native currency. Contact your bank if this is the case. The app will not begin downloading until your credit card has been charged.
This app is of no use whatsoever without a corresponding bluetooth enabled device designed to accept the correct serial commands. So unless you know what to use this app for, don't bother downloading it. See my website for details.
This is just a small app which sends predefined bytes via bluetooth to another bluetooth serial module. Currently used to control a modified RC car. Construction details for the car are free and can be found on my website.
