Worried how your wiggleworm will learn to write his letters? Let a fat juicy caterpillar, smiling snowflake and a fluffy spider teach him. Yum Yum Letters gives kids a gentle introduction to handwriting.

• Learning letters: letter names + sounds + demonstration of letter formation
• Uppercase and lowercase letters, lined paper, white or animated background
• Popular school fonts (ZB, HWT, D'Nealian)
• Motivation system with mini-games rewards
• Customizable settings for up to 30 students
• Detailed progress reports (mistakes marked, video of tracing, reports to email)

This “smart” app is so cheery and full of positive reinforcement and encouragement, kids will view tracing as a game. They have a choice of scratching out letters on a frosty window or munching through alphabet imprinted leaves to get to a shiny red apple. Parents also get choices as they can set the app to follow ABC order or present letters developmentally based on starting point and/or type and difficulty of strokes.

After completing a series of letters kids earn a reward which may be helping the caterpillar turn into beautifully decorated butterfly or making a snowflake from jewel-like ice crystals. What little ones won't realize is even these mini-games are building their motor skills and helping develop the control they will need to write.

This seems good until after playing a few times the game no longer loads. It just freezes after the Kinder Matica animation. The same issue is happening on two iPhones and an iPad. The game is worthless until this is fixed.

The list of features added - lower case letters, pre-writing elements, new games and characters as well as a number of useful features for parents and teachers - progress reports, tracking mistakes made, recording of the child's tracing and possibility to email the reports.

Handwriting and learning letters made into a game!!


Yum Yum Letters will have your students or children immersed in a game-like experience, while they are practicing letter recognition and handwriting skills! Kids can choose from two fun environments to play in. They can use their finger to scratch ice away from a freezing surface as they write, or they can lead a hungry caterpillar along lines to form letters. Each environment has its own reward game, and the frequency of which can be set in the secured parents section. In the frozen section, kids will be enticed to keep playing with a rewarding snowflake activity. In the other section, children will love making creative butteries that come to life! Parents can also choose the font. The HWT font is offered, which is great for kids who have fine motor delays, as well as very young children. Also, the app offers an easy mode, which is ideal for some kids with special needs, as well as a setting for the frequency of the reward games, and a very detailed report for up to 30 students. You will not be disappointed by this app. Kids will be engaged and learning the entire time. The charming graphics and inviting music complement the learning experience. I highly recommend this app for younger kids and those with special needs.
