About this app

The app promotes the use of base twelve, also known as base 12, duodecimal, dozenal, or uncial. There is a simple calculator, calendar and clock to demonstrate its uses. There is also a tab full of information to introduce people to the concept. Please take a look, play with it and learn why there are many promoters of the dozenal system!

Nice design. Like the font! One little thing... The "Save" button and the "Humphrey Point" box are cut off a bit on the right. "Save" looks like "Sav/e"; and the Humphrey Point simply says "Humphrey P". But it's checkable, and it works. (Samsung FE s21)... Maybe replace "Save" with "MS" (Memory Store). And instead of "Humphrey P ;" just go with "Humphrey"... just a thought

Thanks! I'll keep working on the font. I hope I've fixed the display issues; I'll keep working on it. I greatly appreciate the input, I may change these in future updates.

I love this app, but if I were to add something, it would be Widgets and a timer function, that's all

Bug in this calculator. According to the calculator: 1 / 5 = 0.2 (incorrect for base12), when it actually equals 0.2497(repeated). And multiplying 0.2 by 5 results in 0.A (which is correct). The math there is inconsistent.

Unfortunately, this got neglected and needs to be re-published to comply with new standards (it can no longer be updated). However, this helped a lot! There was a greater than symbol used when it should have been less than causing incorrect rounding during conversion. It should hopefully be fixed once it's re-published. Thanks so much!
