handyCalc v0.3

handyCalc v0.3 released:

– Great improvement in solving equations, based on Newton method, now solves much faster and finds more roots.

– Improved graph animation, which is more smooth and does not blink now.

– Several improvements.

Now you can try more complicated equations. handyCalc will try to find all possible results. And if there is something left behind, it will give you a chance to find it on the graphs.


Also the tutorial about solve equations has been updated. link

    handyCalc is awesome! You have done an amazing job. A damn shame you didn’t win the ADC.

    If I was still in school, I would for sure buy a phone app like handyCalc. An actual calculator with similar features costs about sixty bucks! Why would I fork that over when I already have a capable device and I just need to spend a bit for some software. I think you have a marketable product here.

    I think you should make a version for the iPhone. I just got an iPhone 3G. Your app will make top 25 on the iPhone App Store if it’s free or low cost.

    The only graphic calc on the iPhone is really buggy and costs money. You can dominate the iPhone market if you make handyCal for iPhone.

  7. Nice thinking and different aspect of the topic. Liked it.

  8. Great app! When I was taking my physics / math classes back in college this would’ve made me get better grades! if I were still a student I would definitely buy this app.

    Almost perfect all in one calc. You should make it solve integrals and derivatives as numeric analysis. I mean not necessary to solve like “integral x = x^2/2 +c”, but if the boundries are given like “integral x from 0 to 5 = 12.5” as a numeric solution which could be easily implemented.
