Oh please kind sir,
you have put so much in to this, could you find the heart to UPDAT? Now crashing on entry with iOS 15 on iPhone 13. 3 stars because I still have hope!😁
Seriously?
50$ for easy math calculations with ugly interface

Just plain broken
Happy to pay money for something that works. Unfortunately this app for coffee extraction doesn’t. The back end calculation is simply off. My TDS is 1.15, my dose is 37.5 and my end brew weight is 514. Using a calculator you arrive at about 15.75% extraction, but the “tool” says 16.4%. This will make you a worse brewer. Also, you’re forced to set a LRR, instead of having this being a deliverable. You can’t adjust the water weight and the end beverage weight independently. These numbers are locked. Another flaw.

A Useful Tweak
One way in which VST could improve the app for some, while allowing a greater use, and being an industry leader once again, would be to allow for a hundredth place in the dosing. There are more scientific scales like the OHAUS SCOUT or the U.S. SOLID 5000g/0.01g being seen in the industry as coffee is increasingly looked to as a science.
With doses as small as 12g in pour overs and espresso, the difference of a tenth of a gram is nearly a percent of the mass. The difference between tenths of a gram in an extraction yield percentage reading is also considerable at around a quarter of a percent.
Of course most people brewing coffee are not currently using a scale with readings to the hundredth of a gram, but if the app allowed for such, there would almost certainly be an eventual increase in the amount of people who found it a useful tweak. After all, there are more brewers now who are aiming for previously unattainable levels of accuracy in their brewing and charting methods.
