i'm building Cupmark, an android app for specialty coffee home brewers. Brew Lab gives you recipes + a brew timer and tells you what to change when a cup tastes sour or bitter; there's also a short Academy and cupping practice. it's in pre-registration on Google Play now (launch Nov 12), and pre-registering gets a Founding Pass: 30 days of Pro free + a Founding Brewer badge. would genuinely love feedback from people who brew at home: https://cupmark.app/?ref=reddit   submitted by   /u/anasqm88 [link]   [comments]
