Create a small prototype for a mobile app (spelling trainer)

I am attaching wireframes for a mobile app-prototype.

The app should be a simple spelling trainer (for children)
At the bottom of this text, I will provide you with a list of 10 words to use for testing purposes.

The features are very simple:
- User opens the app
- User can "start" the session or "quit"
- If user clicks on "start", the app should RANDOMLY choose one of the words from the list.
- Every word should be asked at least once, before another word is asked a second time!
- Every word should be read aloud (you need to integrate some open source text-to-speech functionality that you can find). For now, English is enough.
- When the user has typed the word and hits the "send" button, the app checks the spelling against the correct spelling.
- The app then gives feedback in the way shown in the wireframes.
- Then, repeat.

Look at the wireframes for details.

Here is a word list to work with:
- developer
- freelancer
- quality
- ambition
- payment
- love
- freedom
- kindness
- honesty
- deadline
