## What is VST CoffeeTools for iPhone?

PROFESSIONAL COFFEE TOOLS for the BARISTA, SPECIALTY ROASTER and COFFEE BEVERAGE EQUIPMENT DESIGNER

Best New Product SCAA EXPO 2010

VST CoffeeTools™ allows professional and home users to quickly compute proper brew formulas using any method of brewing coffee or espresso. Used with a coffee refractometer (not included) VST CoffeeTools will apply measurements of brew formula and coffee TDS to compute normalized extraction yield – a crucial metric for ensuring the sweetest coffee and espresso. 

COFFEE BREWED TO GOLD CUP STANDARDS
•Use VST CoffeeTools™ with any VST coffee refractometer to compute brew recipes and measure results to meet internationally accepted Gold Cup standards as practiced by the Specialty Coffee Associations of America (SCAA) and Europe (SCAE), as well as the Norwegian Coffee Association (NCA) and European Coffee Brewing Center (ECBC). 

COMMUNICATE
•Recipes & Measurements can be eMailed and shared with customers, clients and colleagues for quick, detailed communication of all brewing parameters. Full database sorting, import and export is supported.

COFFEE MODE
•VST CoffeeTools™ for Coffee offers professional baristas and specialty roasters the tools to design, measure, diagnose and refine any brew method to ensure excellence in coffee brewing.
•Metric, English (U.S. Custom) or mixed units, and conversions of weights and volume is fully supported.
•Compatible with all drip and immersion brewing methods and works with any VST Coffee refractometer displaying % TDS to 0.01% – temperature corrected for coffee. Accuracy recommended: +/- 0.05% or better. 
•Save, share, import measurements and details, including TDS, Ext Yield, Dose, Brew Formula, CO2, Moisture, Brew Time, Brew Method, Temperature, Pre-Infusion, Grinder/Setting, Roaster, Roast Style, Farm/Farmer, Barista Name/Notes and much more.

COFFEE LITE MODE (discontinued)

ESPRESSO MODE
•VST CoffeeTools™ for Espresso offers professional baristas and specialty roasters the tools to design, measure, diagnose and refine espresso extraction.

•Presets for Single, Double or Triple shots as Normale, Lungo or Ristretto can be loaded and custom preset for personal preferences.
•Works with any VST Coffee refractometer displaying % TDS to 0.01% or 0.1% – temperature corrected for coffee. Accuracy recommended: +/- 0.1 % TDS or better.
•Save, share, import measurements and details, including TDS, Yield, Dose, Brew Formula, Shot Time, Temperature, Pressure, Pre-Infusion, Grinder/Setting, Roaster, Roast Style, Farm/Farmer, Barista Name/Notes and much more.

SUGAR MODE
• Sugar mode allows beverage industry professionals to measure Sucrose, Glucose, Fructose and Invert Sugars at any temperature from 15-40 Deg C for use in concentrates and related sugar-based beverages.
•Simply enter Refractive Index and Temperature from any refractometer to compute and displays all values for Specific Gravity, Density, Total Weight, Mass Fraction and Dry Substance weight.
•VST CoffeeTools™ for Sugars is accurate to +/- 0.00003 nD per ICUMSA Tables (1998 & 2000). Final accuracy depends on accuracy of instrument.

CORN MODE
•CORN mode allows beverage industry professionals to measure High Fructose Corn Syrups HFCS42 and HFCS55 at any temperature from 10-50 Deg C for use in concentrates and related HFCS-based beverages.
•Simply enter the Refractive Index and TEMP from any refractometer to compute and displays all values for Specific Gravity, Density, Total Weight, Mass Fraction and Dry Substance weight.
•VST CoffeeTools™ for CORN Syrups has been tested against the Corn Refiners Association tables for syrup composition, and is fit to be accurate to better than +/- 0.0001 nD and less than +/- 0.02 % Mass Fraction. Final accuracy depends on accuracy of instrument.

### 3/5 — Oh please kind sir,

*2022-10-22*

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!😁

### 1/5 — Seriously?

*2021-11-15*

50$ for easy math calculations with ugly interface

### 1/5 — Trash app

*2021-09-20*

Trash

### 1/5 — Just plain broken

*2021-03-11*

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.

### 4/5 — A Useful Tweak

*2020-05-14*

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.

### 1/5 — Rubbish

*2020-05-12, version 1.4.1*

This used to be useful but it has been stripped of function, which has put me off buying anything from this company.

### 5/5 — I want to download again

*2020-03-07, version 1.4.1*

I used to pay.

but it can’t be used

my pay number.

### 1/5 — Just a sales tool

*2019-11-23*

This app does very little beyond allowing you to buy plug-ins that cost significant money.

### 5/5 — My IPhone icon looks OK

*2019-06-29, version 1.4.1*

However My IPAD icons looks not ok. There’s no coffee cherry, But only circles and squares.

### 5/5 — Liquid Retained Ratio

*2018-01-22*

Coffee mode LRR.

Why it cannot be set to zero?

I think it could be set to zero.
