MS Edge Compatible
MS Edge Compatible
I've never tested with Windows Edge browser, so I couldn't find this bug.
But today, the problem of Microsoft Edge browser has been fixed.
And also, the android version of this app has been released.
Regarding the security of android apps, it is said that there are
vulnerabilities of reverse engineering and following repackaging attack.
But the technology of PWA (Progressive Web App) is said to be safe.
The technology of It depends on browser's one, so it's as safe as
the browser you use. Also, if you even don't like to install apk, still you
can play the browser version of this app.
I hope people to play this app with their smartphones anywhere at any times
regardless of the devices they use like ios, android, windows and so on.
There are another complicated issues. The problem of copyright.
To tell the truth, I'm not an expert of abacus so I referred to lots of books
of abacus and math. And this app is like a GCD (greatest common divisor) of them.
I've borrowed lots of mathematical ideas from them without consent.
I respect the authors of those books and want to pay homage to their ideas, so
the algorithm of calculation follows their ways. Although I've added another
original ways at first, but eliminated them later because I thought my ideas are not
sophisticated enough and not tested by so many people for a long time
and they'll confuse users.
If my app is profitable, there might be the legal problems of copyright, but still
it's not profitable. And I think this app won't infringe the rights of other books
but contrary this app serves as an introduction to those relevant books if users get
interested in them seeking more knowledge.
I've found that the development of apps require me to think various complicated matters.
But I'd like to keep updating this app when I have enough time.
