The publisher was Chin-Apse Pty. Ltd. This is app was something of great use to many people. It is a simple calculator of common blasting ratios and statistics. modern browsers support HTML and CSS better now, as such the app that died on the Apple Store can now live again. Created code is in HTML/JS/CSS. Thank you. Brent Buffham © 2021.
