Hey Dudes, Dunno if this is the right place to post this... Anyway, I fell short of my target gravity on a brew day recently and thought there'd be a simple way to work out how much DME to add to correct it. Lots of googling brought up a lot of discussion threads in various forums and articles, but nothing along the lines of a calculator. So I made one. It works as a phone app on iOS and Android or through a browser Its pretty simple - its just a spreadsheet uploaded to Openasapp.net First you click on this link -> https://oaa.app.link/launch-app-f43f73f9-acda-47c0-9ec9-85bfd323546d and it takes you to a landing page with further instructions (no spam or foul play here I promise) From there, follow the instructions to send the actual app link to your phone and open it. Still needs a little fine tuning, its basically a spreadsheet hosted on a website with a cool interface. Hope this is of use to someone!
