Welcome to iteachsci.com

Welcome to my site! These are just a few of the web apps I've been working on. They all have issues, but the benefits far outweigh them. Enjoy and use at your own risk. NO personal information is stored anywhere outside of your browser / computer. This also means that you must back up any files you create or risk losing hard data entry work. Always keep a backup!

If you've gotten this far, you know who I am and know how to get in touch with me. So... if you have any questions just text, call or email me. I like coffee☕ and beer🍺. If you enjoy the apps, buy me one the next time you see me!
