VST CoffeeTools™ for iPad
Design coffee brew targets and compare measured TDS/extraction data on a brewing chart.
Useful for users who understand the measurement assumptions
Dose/water/beverage conversions link design targets with recorded results.
Keep in mind: Calculations do not measure TDS without suitable equipment or guarantee taste; calibration, temperature and retained-liquid defaults affect comparisons.
