It is a fairly good idea, but i doubt the capability of device when some foods are hidden and how to measure the size of it?
How fast does it take to process? What if there is no internet connection?
What if the foods are hidden underneath?
Many loop holes in how the product can function properly but the idea is a good idea none the less and with more time, the idea could have been near flawless.
The idea is pretty good but there are many flaws. What happens when the device runs out of battery?
I think you would need to charge it.duh lol
