Hi,
here a small app for children to learn how to speak numbers. With 5 wheels you can construct number with 5 digits. Then with a button the number will be spoken by the app.
This is e.g. useful for different languages, because e.g. in German or French it is not so obvious how the number is to pronounce.
Very cool! I find the numbers above and below the current value distracting. Other people might like them but I would prefer just the value with the up and down arrows (and I’d suggest an actual image for those buttons rather than a “v”) unless you had a true scroll wheel chooser.
