Plateknow is made by AI Joy Apps, an independent app studio in Taiwan. The App Store and Google Play list it under the founder’s developer name, CHEN GUAN-JHEN — the same studio, one name for the stores and one for everything else.

What Plateknow is

An app for iPhone and Android that reads calories and macros from one photograph of a meal, as a range rather than a false-precise number, and checks in later on how the meal sat.

The studio

AI Joy Apps also makes 2Live, a live-wallpaper app, and 垃圾車, a garbage-truck tracker used across Taiwan. Its site is aijoyapps.com.
