We are coffee people that wanted a better way to calculate extraction of our coffee's. Using modern tools & basic specs from our coffee's we are able to now measure the extraction & rely more on science in conjunction with taste in order to produce the best cup of coffee for ourselves and those we serve.

We wanted to produce a beautiful design that helps represent the amount of work we put into our coffee which & our roasters put into sourcing & producing fantastic coffees.

Why would I use this?

Café's: Using quality roasters & quality beans isn't the only thing necessary in serving an awesome cup of coffee. Preparation & Brewing play an important role in a good cup of coffee. Our Optimal Coffee Extraction app will help you find out if you are inline with the SCA guidelines for perfect extraction.

Roasters: Want to find perfect specs for your coffee's that you can give to your café? Finding the proper dose, time, & final output for espresso & filter coffee is a helpful thing to pass onto your café's and other wholesale clients to uphold proper quality standards.

Things needed for this app to work:
A Refractometer, either Atago or VST would work.

Gorgeous interface & useful tool

I am a coffee fanatic and coffee shop owner, my team and I use this app to help dial in our coffees especially when we have palette fatigue. It is always great to have this tool to make sure our coffees are properly extracted.

Sleek - Easy to use

As a former barista using this for my at home setup, it was exactly what I was looking for. It’s a clean, sleek app that’s easy to use and does exactly what it says it does. The dark mode is beautiful and my tired pre-coffee eyes appreciate it as well.

Love interface, but...

every time I try to log a measurement, the app crashes and I lose the data. Calculations work.

Edit: logging works now. Updated to 5 stars.
