As answered by people managing Motion Magic Physics Simulator and Cert Decoder.
Motion Magic Physics Simulator's answer
Motion Magic started from one problem: students get stuck trying to connect formulas to real motion. It was built to give them a space where they can try things out, see the results, and finally make sense of what’s happening.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
Motion Magic Physics Simulator's answer
Students taking their first introductory physics class who need something clearer than a textbook and more hands-on than a calculator.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Motion Magic Physics Simulator's answer
Most tools only show preset demos. Motion Magic lets you experiment, make mistakes, adjust ideas, and actually understand what the motion is doing instead of guessing from a diagram.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
Motion Magic Physics Simulator's answer
College physics students, Community college classes, and just Independent learners!
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Motion Magic Physics Simulator's answer
Motion Magic lets you build and explore physics problems the way you think about them. You place objects, push or pull them, change numbers, and see exactly how everything moves immediately.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
