Pros and cons of Calculus doodlus app for iPhone and iPad

Calculus doodlus app good for

Finally supports 4 inch screen - Thank you for the update of this awesome app!
I wasnt expecting much when I picked this up, but its now become my favourite calculator on my iPhone and my iPad when I want to keep track of several calculations and variations. I still use the Apple calculator for quick one-off calculations, because Calculus doodlus remembers all calculations, and as far as I can tell theres no way to delete a single page or calculation -- the only option is to delete all pages. I wish I could edit a previous calculation by positioning the cursor on a number and changing one digit, with the result of the calculation changing, as I sometimes make mistakes and would prefer to correct the calculation than type it all over again.
I bought this app largely for the paper tape. Once I started using it I found it to be easy and intuitive. I was surprised how much I liked using the drawn style font and liked being able to have each digit appear exactly to my taste.
This calculator is great. I use it all the time. I am a contractor and need to be able to review my entries. Well done.
This is my main calculator. It works well and having the numbers in my own handwriting is great. I like the quizzes too. A little mental exercise always helps.
Great it would be better if there was a training games for the tests and handwriting with letters then i would give it 5 stars

Some bad moments

This is a fun calculator app! My favorite one when I need to do some quick math. It looks just like scratch paper! We even use it to keep score in our games. I really like that you can edit each number to fit your own handwriting. My daughter is learning Japanese and uses those Kanji symbols!
The app is easy to use and just right size wise. Awesome app!
The app is awesome, easy to use, and a quick-draw solution for everyday calculations; however, I preferred when I could customize the color choosing from a color spectrum instead of 10 or 12 preset options, as it is now.
Loved it before but now even more with landscape mode added. Awesome!
I just love it, soooo flexible. Awesome. And great addon of quiz (for all of us math geeks). Buuuuut, i would of given it 5 stars for this version if it didnt crash when I delete a plus sign or faster load on past pages. Always room for improvement. I use iOS 5.1 newest and iPhone 4s. Keep it up.
Love that it Displays similar to how students have to "show work" when they do math homework. My son with dysgraphia uses it for all his math assignments. Prior to this app, he had to have a scribe for math. Would love to see more functionality added, such as the ability to add letters or symbols by tapping on the screen
