### 5/5 — No Notes

It does exactly what it says it does. Perfect.

### 2/5 — No ounces?

Wow no conversion for good old ounces

### 5/5 — Simple, compact, useful.

*2021-04-05*

A very handy tool for quick coffee to water ratio calculations, specially when you’re testing new brews. Would be cool to have the possibility to save fave presets but it’s already really useful and reliable as it is.

### 4/5 — Perfect!

*2018-01-26*

Finally, someone made a simple, easy to use, easy to read, and deadly accurate coffee ratio calculator. Not only does this calculate PROPERLY, it gives you the yield. Which means it accounts for coffee bean absorption. Hats off to the developer!  THANK YOU!
