Been using Epoxy River Calculator for a couple months now. It’s basically an app that lets you easily figure out how much epoxy you need for your DIY river projects. Pretty solid if you’re into that kind of thing.
Here’s what you do: you enter the length and depth of your pour, then start adding width measurements. The app will calculate the total volume as you go. There’s also a reset button if you mess up a measurement. It’s got a pretty clean interface and the calculations seem pretty accurate.
Look, if you’re into DIY epoxy projects, you’ll probably like this. It’s not perfect – sometimes the app crashes if you enter a ton of width measurements – but overall it does the job. Worth checking out if you need to figure out how much epoxy to buy.
