STORY ----------------------------------------------

When Kalley shows her dad her drawing for a new machine, he is baffled by the confusing collection of hammers, gears, fire, smoke and conveyors. As Kalley explains each part of her invention, the drawing comes to life even as its overall purpose becomes less and less clear to her dad. It is only when Kalley explains the machine’s final component that her master plan to keep her dad from commuting is revealed.


So, there really is a ‘Kalley’. She really drew a machine. Her dad couldn’t build it. So they made an app out of it instead. Full story at kalleysmachine.com.

FEATURES ----------------------------------------


Kalley’s Machine was crafted with interactivity as the first priority. Satisfyingly touchable controls put kids in charge of each twist and smash of the machine. Controls come in a wide machiney variety:

● Cranks
● Sliders
● Dials
● Levers
● Switches
● Buttons

With the machine, kids can:

● Smash Stuff
● Inflate Stuff
● Shrink Stuff
● Burn Stuff (or lightly toast it)
● Paint Stuff
● Grab Stuff
● Drop Stuff
● Mold Stuff Into Shapes
● Do A Few Other Things Including...


Kalley’s Machine is a story based on a 4 year-old girl’s drawing. As such, it includes cats. They are completely irrelevant to the story. However, they are way fun to harass.

Tease them. Scare them. Puzzle them. Adore them. We think you’ll love the cats.


Cuz it’s a story, right? Of course, you can read the story the old-fashioned way. But, to aid new readers, we’ve also included two helpful interactive story features:

● Read-to-Me, narrated by Kalley and her dad with highlighted words.
● Touch-to-Read, where words are spoken when they are touched.


Honestly, we designed this story to be fun. But if you're not careful, you might actually learn something too!

The interactive medium offers kids great chances to explore some basic concepts which are both safer and less messy than their real-world alternatives. Creative parents may recognize the opportunity to discuss:

● Subtractive Color Mixing
● Pressure/Temperature Relationships
● Gear Ratios
● Air Pressure/Vacuums
● How Overcooking Can Burn Stuff


We have made this app super-safe for kids by having:

● No Ads
● No In-App-Purchases
● Parental Gates in Our Parents Section

What’s New

Version 1.4.0

The cat party is now full on automatic! All six available cats are ready to play upon update!

We originally included a cat party after the story to encourage sharing. You had to post about our app to get more cats. We have ditched the sharing nonsense and just given you the cats up front. ENJOY!!

Great interactive book interesting for Maker Ed

I generally don’t take the time to review apps . .but this one got me really excited. I am an education professor and also an Apple Distinguished Educator and i only heard about this App when it was free for a day. its an interactive book that has appropriate reading strategies. I just spent about 30 minutes using it with my 4 year old nephew. He played it again and again and liked each of the machines. One thing that I thought was cool, he kept asking why the “marshmallows” reset on each screen. Auntie I made it small, why is it big again? it lead to a good discussion on how programmers make each page work.. (His daddy is a computer engineer).

The reading level is appropriate and it gives good feedback and allows each word to be spoken. The only bit of suggestion for improvement I would include would be to have something interactive on the last page or the the end page. My nephew was a little disappointed that everything was just “over” . .but he went back and started the book again.. (Maybe an interactive hug) ..

So who would be interested.. I think this is really appropriate for maker education as well.. i could see using it as an intro to a lesson on designing machines.

My kids love the cats!

Please allow parents to disable swipe

My toddler likes this game, but she finds it very frustrating that when she is just touching the screen to make something move, over half the time she swipes to another page. Since this app is premised on kids touching the screen, please at least allow parents to disable the swipe feature.
