2025-02-27	RA*****	I use VST Coffee Tools Pro every day to dial in and calibrate my coffee setup, and it’s been a game-changer. The app provides precise extraction measurements, helping me fine-tune grind size, brew ratio, and TDS for consistently great coffee. Whether I’m making pour-over, espresso, or another method, this app gives me the data I need to optimize every cup. It’s intuitive, reliable, and indispensable for anyone serious about coffee brewing. Highly recommended!

2018-01-28	es*****	i have two requests: can we add hundredths of a gram to the dose in percolation mode? this app is set up great for batch brewing, but i brew with 12g doses in my v60. (a good recipe for a high extraction) in my case, changes in dose of one tenth of a gram result in a change in extraction of nearly a quarter of a percent. (21.75% versus 22%) because of this i bought a cheap scale that reads to the hundredth of a gram to weigh my doses, letting me view a more accurate extraction resolution. it doesn’t seem ridiculous to weigh a low dose (even espresso) with more accuracy than a tenth of a gram. but as things are, i calculate my extractions by hand. secondly, could the LRR be optional? there are often times when i’d like to input my actual BW and BEV weight and they are not quite matching my usual LRR. then i have to manually fiddle with the LRR until it is adjusted correctly.
