App (Code)
Like App Inventor, but with Python: design your screens with views, add buttons and widgets, and write the code that runs when each one is tapped.
- 🏠 Smart home with a password
- 🤖 Robot remotes
- 📊 Sensor dashboards
- 🧮 Calculators & tools
- 🎮 Games & quizzes
- 🗣️ Talking apps

All about App (Code)
Your mentor’s quick guide: how it works, what to try next, and answers to common questions.
Add views and parts. Each view lines its parts up — across (Horizontal), down (Vertical) or in a Grid. Tap a part for its settings.
Every button and widget has its own “when clicked” Python. All of it together is the full code — imports are added for you.
Try it with the Virtual Board, then connect your board by Bluetooth or IoT. Watch each line light up as it runs.
🧗 What to make next
A hello button · a counter · show text from an input · if / else
Calculator · quiz · dice game · timer and stopwatch
Password-locked smart home · robot remote · live sensor dashboard with alerts
🎒 What you need
- 💻A computer, tablet or phone with Chrome
- 🧩A TinkerPy board with a Project — or the Virtual Board to practise
- 🐍A little Python: variables, if / else — the examples teach you
- 🎨Ideas! Every view has colours, padding, corners and shadows
❓ Questions students ask
What is the difference between App (Blocks) and App (Code)?
App (Blocks): drag widgets, no code. App (Code): you design the layout with views and write Python for every button and widget, so your app can think — passwords, scores, timers, conditions.
Is this real Python?
It is Python made for apps: variables, if / elif / else, loops, maths, text and lists — and it starts instantly on a phone. No def, global or import needed in your events.
Can I use all the App (Blocks) widgets?
Yes — doors, fans, lights, sensors, joysticks, camera AI and more, plus new parts like text inputs, sliders, switches, progress bars and gauges.
How does it talk to my board?
bluetooth.send("A") sends a letter, just like App (Blocks). When the board sends data back, your “when data arrives” code runs.
App (Blocks) builds a remote control in a minute — just drag widgets.
