Ask Grok like this
“I use Code on the Go on a phone. I have never written Kotlin. Give me the smallest Hello app, file by file, and explain each file in one short everyday paragraph.”
Keep them tiny · Stage 5
Huge apps are many tiny apps glued together.
Wait until Python files feel normal. Then pick one phone IDE. Then make a button work. These three ideas are enough for weeks 6 to 8.
B
A counter
Plus and minus. The number goes up and down. Same screen, two buttons, one sticky note that holds the count.
C
A notes box
It remembers what you typed. That is the to-do script wearing an app coat.
Still later
Stage 4 Git and Stage 5 the IDE sit on the Path when those pages open. You already have the library for both.
Next step
Pick extras for more tiny files, or one IDE later. Not both tonight.
