Hello, I’m 14 years old, I’m learning about khmer just now! I started using this app when I was 7. And yes the creator is right! I learn about constants,vowels,jobs,vegetables, all those stuff just from this app! I suggest if your Asian or if your any kind of type, you should download the app (if you want to learn khmer, your choice) the app is great!!!! You should use it if you want have a great day!!
