The free vocabulary trainer for schoolchildren. Listen, write, defeat bosses: with Vocabulary Champion, your child practises the words from their school textbook in short rounds – and will want to carry on straight away tomorrow.
Here’s how it works
No download required: the app runs in the browser and can be pinned to the home screen.
A username and password are sufficient. Parents give their consent; an email address is not required.

The words from the textbook, sorted into groups. Alternatively, the teacher can make them available to the whole class.

The robot reads aloud, and your child writes down the answers. Every correct answer earns experience points and coins.

Online or as an app
One account for everything: anyone who practises online and later downloads the app logs in with the same username. Progress, medals and coins are the same across all platforms.
Get started straight away, no installation required
For iPhone, iPad and Android · coming soon
Features of the vocabulary trainer

Every correctly spelled word flies at the boss, letter by letter. If you make a typo, you get ‘???’ back. This way, your child sees the correct word at the exact moment of the hit.
The robot says the word, and your child types in the translation or writes a dictation.
Daily and weekly missions with rewards keep your child engaged every day.
From Bronze to Platinum: progress is visible, for example as a ‘Spelling Pro’.
With the coins you earn, your own robot can get a helmet, crown or cape. All without spending any real money.
Enter the date and groups: the app counts down the days, plans daily practice and tackles uncertain words first.


Explanatory video
Create an account, enter vocabulary, practise, defeat the boss, plan for a class test: the video shows the app just as your child uses it.
Who is it for?
Beating the boss is so much fun that I don’t even realise I’m learning vocabulary.
No more arguments about learning vocabulary: my child practises on their own, and I can see what they’ve already learnt.
I enter the lesson’s vocabulary once, and the whole class practises with it, without needing the children’s email addresses.
Data Protection
A username and password are sufficient. A parent’s email address is optional, required only for the ‘Forgotten password’ feature.
Stored in a data centre in Ireland. The password is stored only as an unreadable hash value.
No in-app purchases, no advertising networks, no profiles created about your child.
In the parents’ area, you can delete the account along with all associated data.
Vokabel-Champion is currently being tested. Try out the app together with your children and let me know what works well and what’s missing. All feedback goes straight into the backlog.
