Ratios are fixed for each new type, e.g., 1:16 for pourover. Useless if you want stronger or less robust cups. I uninstalled after using for a couple of minutes.

Fantastic Ap suitable for all coffee brewers. Helps to determine the correct ratios using either Metric or Imperial methods. Has it all.

Does exactly what it says on the tin, and doesn't collect any personal data. Perfect.
