DotToDot numbers & letters (formerly known as DotToDot number whiz) is an educational app for the iPhone, iPod touch and iPad that brings an old children’s favourite into the 21st century.
Dot-to-dots are a great way to develop children’s number recognition and counting skills, but now they are more fun and educational than ever:

Aged-based settings that make it more challenging for older children (4-5 year-olds just have to count up in 1s, older siblings may have to count in 2s, 4s or 7s or know the order of the alphabet)
Leaderboards so your kids can try to beat their own or their siblings’ best times
Practice for fine motor skills
Fun animation, graphics and sounds your kids will love
12 dot-to-dot puzzles

FAQ.

The app's crashing or getting stuck. What can I do?
First thing to try is to turn your iPhone/iPad completely off and then on again. If this does not resolve the problem, please report it as a bug to us via the help and support section within the app's Parentzone.
How do you move onto the next puzzle?
You move on to the next puzzle by touching the right arrow button in the top-right of the screen.
And, if there isn't a right arrow button?
If the player has the setting switch on that they have to unlock each puzzle, then they have to beat each puzzle's unlock time before they can move onto the next puzzle. The right arrow button will not be shown if they have not unlocked the puzzle.
You can switch this off through the player's settings.
How do change the age of a player?

Choose the player on the home screen,
When the screen appears that shows a dot-to-dot puzzle, touch the "player settings" button in the bottom right hand corner.
Near the top of the screen that appears there should be a "edit player" button - touch this
A new screen will appear and you can change the player's age here.

How do I delete a player?

Choose the player on the home screen,
When the screen appears that shows a dot-to-dot puzzle, touch the "player settings" button in the bottom right hand corner.
Near the top of the screen that appears there should be a "edit player" button - touch this
A new screen will appear and half-way down this screen, there should be a "delete player" button.

Why is the time given for completing the puzzle longer than I think it should be?
Is there a message on the screen saying how many times you touched the wrong dots? If so, you touched some of the dots in the wrong order, and each time you do this a time penalty is imposed.
