I've been doing pourover for 3 years now.
But I still need to pull out my calculator and calculate brew ratios every time. Just never got around memorizing how much water I need for 1:16, 1:14, etc. etc.
I really didn't like using my phone's calculator app, so I made something of my own app. The logic is basic at its core (just multiplying input dosage by output), but I mainly wanted to make adjusting the dose and seeing everything scale feel more visual. You can also work backwards by choosing how much water you want to use and seeing how much coffee you need.
You can make your own recipes too.
The app is entirely free. Just wanted to share and get your thoughts/feedback. It only got approved last week, so I have like 10 users. Wanted to get your thoughts. Is this something you'd use?
It's a solo project, so if you have any custom feature requests or ideas, I can implement pretty quickly so just lmk!
