Is It Really Keto app for iPhone and iPad

"Confused by whether something is Keto or not? Just because it says Keto on the label doesn’t mean the ingredients are acceptable to someone practicing Keto.
There are different levels of Keto and this app follows the guidelines of strict Keto.
Simply scan the bar code of each item and the app will tell you if it’s keto.
Yes, it’s that easy.
Now your app has access to the largest database of foods. Every product has a bar code on the label – however not every company submits their bar code to the database.
Companies change their ingredients all the time but may not update the database for a while.
Kindly note the app only works with food products not vitamins, supplements or non-food items.
Also big box chains very often do not list their products in the database.
If the product does not have a bar code, you can enter the product name and ingredients and the app will tell you if it’s keto.
This will rapidly become your favorite app."
