The Practical Diet Alexa Skill allows you to use your account on https://practical.app with only your voice. With its extensive database, you can log nearly any food just by saying "Alexa, tell Practical Diet to log <food quantity and name>". For example, you could log your lunch by saying "Alexa, tell Practical Diet to log two McDonald's cheeseburgers". Tracking your water intake? "Alexa, tell Practical Diet I drank twelve ounces of water." Prefer the metric system? That's fully supported as well ("Alexa, tell Practical Diet to log one hundred grams of Sargento cheddar cheese.").
It's just as easy to get the data out as it is to get it in. Need a summary of your day? "Alexa, ask Practical Diet for a summary." (or "Alexa, ask Practical Diet for a summary for yesterday" or even "Alexa, ask Practical Diet for a summary for last Wednesday"). Tracking macros? "Alexa, ask Practical Diet for my macros". If you've entered macro goals on the Practical Diet website, you will get not only your macros, but advice on what to eat for the remainder of the day to hit your goals.
“Alexa, ask Practical Diet for a summary of yesterday”
