electronics to track it all?

Options
Hello, I'm looking to help out my mom, she started her journey a month ago, no carb diet, now she's bored with it. I'd love to get her something she can easily use (she doesn't have a computer, no ipod or iphone, etc.) I'd like her to have something electronic she can keep in her purse or something that will count her calories, track her progress (ideally I need her to have something uncomplicated like MFP she can take on the go) any suggestions? I thought about an android. She's 100% determined, but I'm afraid she's going to get bored with the old fashioned way of writing down calories. She has no internet service, so no way to look up info. on dieting, etc. Any help would be a blessing! Thanks so much!
