Your child builds a game. Then reads the Python behind it.

Codekin is a block coding app for children aged 7 to 13. Kids snap blocks together to drive a rickshaw, fly a kite or guide Bit the robot through a maze. Every block shows the real Python line it stands for.

Coming soon on Google Play

Free to learn. No account. Lessons work without internet. Short, child-safe ads between games, or remove them once for US$2.00.

Made for how children in our part of the world learn

Five languages

Bangla, English, Hindi, Chinese and Arabic. Switch any time. The English name stays under each block, so kids pick up the words programmers use.

Reads every step aloud

A child who cannot read well yet can still follow along. Every instruction is shown and spoken in the chosen language.

Works offline

Every lesson, puzzle and quiz is inside the app, so learning works the same on a bus, in a village or on a phone with no data pack. The internet is used only for ads and for Google Play purchases.

Real Python, not pretend code

Blocks turn into Python and Python turns back into blocks. With a grown-up's OK, older kids can type the code themselves and see their mistakes explained line by line.

Games they know

Rickshaw Runner, Kite Festival, Cricket Batsman, Mango Collector, Hungry Fish, Snake and a Jungle Monkey. Plus a calculator and a counter app they build themselves.

Help when they are stuck

Every lesson step has a hint. Every puzzle has three: an idea, the first blocks, and finally a working answer they can run and study.

What your child learns

Sequences: steps run in order, and a computer never guesses.
Reading and writing Python: what a program prints, which line is the loop or the decision, and how to fix a broken line.
Loops: repeat, forever, and repeat until.
Conditions: if, else, not, and, or.
Events and variables: what starts a script, and boxes that hold a score.
Functions: making a block of your own and using it again.
Algorithms and debugging: 29 Robot Maze levels, five of them start with a bug to find.
Computer basics: input and output, the processor, memory and storage, files, 0s and 1s, hardware and software, the internet and staying safe online. Nine short cards, each with a quick question.

There are 11 guided lessons, 53 puzzles with stars, 12 short "What is a loop?" style cards, 9 Computer basics cards, a daily challenge and badges to collect.

Quizzes to check what they know. Seven practice quizzes (42 questions) ask children to read real Python and say what it prints, tap the loop or the line with the mistake, and put lines in order to build a working program. A 15-question final quiz at the end of the course gives a score and a pass mark, and parents see every result in the progress report.

Questions parents ask

What age is Codekin for?

Ages 7 to 13. A seven year old can start with the short instructions and read-aloud. A twelve year old can move on to typing Python.

Does it show ads or ask for money?

Learning is free. The app shows a short ad now and then, only between games and quizzes, never while your child is playing or answering. Ads are set for children: no personalised ads and no advertising ID. A grown-up can remove ads for good with a one-time purchase of US$2.00 (shown in your local currency), from the grown-up area behind the multiplication question. Every lesson and quiz is the same either way.

Does my child need an account or internet?

No account, no email, no sign in. Lessons, puzzles and quizzes all work offline. Progress stays on the phone and is never sent anywhere.

Can I see what my child has learned?

Yes. Open the grown-up area (it asks a quick multiplication question first) for a progress report: lessons, levels, stars and ideas learned, world by world.

The voice does not speak Bangla. What do I do?

Read-aloud uses your phone's own text-to-speech. Open your phone settings, search for "Text-to-speech", and install the voice data for your language. See the help page for steps.
