This app is what was lacking on my phone. The large font is perfect and it makes my phone complete. I will not ever be uninstalling this one. I look forward to more apps from this developer any day.
Really Useful I'm afraid as I get older my mental arithmetic isn't as good as it used to be and it can be very reassuring to have this little app on my device (particularly at work!!)....EXCELLENT!!
Real calc. Every device I have had, I use this calculator. It has everything you'll need. I used this for all my math classes through college! I've found nothing wrong with it! Natural Calculator
