Visually compare, add, subtract, multiply and divide two fractions with a unique and simple interface.

Oh No Fractions! is built on the amazing feedback and response we had with the original free Curious Hat Lab app.
We added 4 new fraction operations, so now you can perform the following operations on two fractions:
- Compare
- Add
- Subtract
- Multiply
- Divide
The visualization of fractions with simple, effective and interactive graphs, allows the user to explore the solution at each step.
Statistics are kept for each successful and unsuccessful attempt to solve the problems.
This feature is very useful, in the classroom for example, to monitor the child progress.
Stats can now be shared via email.
Oh No Fractions! was featured multiple times by Apple in the Education Store.
Latest reviews of Oh No Fractions! app for iPhone and iPad
My daughter really learnt fractions with this app. Greatly recommended
I wish the app would allow larger fonts. I cant read it.
The only mode of operation is a slider that you move to select the appropriate denominator and consequentially, the numerator. One quickly learns that the correct answer is when the numbers and hash mark on the scale turn white. So all one needs to do is to move the sliders until they change to white. You think a kid wont learn this gimmick quick? I wouldnt call this learning fractions.
Please change the term "nominator" to "numerator" to refer to the top number in a fraction.
Great idea, poorly executed. The slider bars are not sensitive enough. I spent a minute trying to set it at 2, and could only make it bounce between 0 and 8.
