Use the same measurment (portion, g etc.) for adding food as last time
I very often have to change the measurments from portion to gram or the other way around.
It would make sense and save time to store what measurment was used last for a specific food.
The probability that you use tha same measurment again for the same food is pretty high.
It is enough to store such information locally on the phone. It is not tragic to lose such data when you change the phone.
