We are on a mission to help you brew great coffee every time. Use KoHi and your favorite specialty coffee beans to take your brewing process to the next level.
KoHi is a coffee brewing timer, calculator, and recipe manager with a clean and clever interface. No more guessing at the ideal amount of coffee and water to use to achieve the perfect brew—KoHi does the math for you. We currently support Chemex, Hario V60, Press Pot, Clever, Kalita, AeroPress, Bonmac, Woodneck, and Gino brewing methods. It is the prefect companion for your favorite manual brewing method.
KoHi’s advanced brew calculators and timers help you brew with laboratory precision for consistent extraction every time. Tell KoHi how much coffee you would like to brew, and it calculates the exact amount of beans and water to use for the perfect cup of coffee. KoHi also paces you through the pre-infusion and infusion phases of brewing for a more accurate and consistent brew.
KoHi's recipe manager lets you create and store your own recipes too. Share your favorites with friends on Twitter, Facebook and email (iOS 6.0 or greater required for Twitter and Facebook).
Experiment, taste, share and enjoy coffee creations with KoHi.
*Note: You will need a gram scale to use with the KoHi app.

The cursor in the recipe editor is back: -Our cursor now shows users where they are in the textfield.
Huey Lewis was right: -It's hip to be square -The UI has fresh new elements for 2014
Code clean up: -Removed an unused code library -Removed some legacy functions
1.14.13 (Nov, 2013)-

The pixels area all happy again and your coffee will now taste better.
1.14.12 (Nov, 2013)-
YIKES! There is a bug. If your dots are colliding with the instructions, you are not alone. We fixed it. However, it's going to take a few days before the new, new version replaces this broken version.
We are sorry for the booboo. Thanks for using our geeky little coffee app.
--- Some subtle and pleasant changes for iOS versions 6.1 and 7:
User Interface -new navbar buttons for iOS7 -fixed segue bug for iOS7 -gradients for launch icons
File Manager -fixed recipe iteration code
1.13.12 (Aug, 2013)-
-Fancy new dots
-Updated Email, Twitter and Facebook scripts
KoHi 1.11.10 provides more accurate brew amount predictions in the recipe manager and now indicates when user action is required during the brew process.
Bug Fixes: -improved code to handle smaller brew amounts for some recipes.
Enhancements: -More accurate brew amounts for base recipes. -More accurate brew amount calculations for new recipes and user updated recipes. -Larger screen flash during brew phase transitions.
Features: -New UI component to signal user action is required during the brew process.
Performance: -Improved code structure.
Notes: This update primarily improves KoHi's estimated brew amount calculations. Predicted brew amounts for custom recipes will be more accurate. We recommend that user's review all custom recipes and adjust the water amounts as necessary. Quick tip: just tap in a ratio or water amount field of the recipe manager to activate the edit mode. Then swipe down to update the recipe with the new brew amount.
Or, don't change the custom recipes. The brew timer will simply use the existing recipe to make a little bit more coffee than it did before.

App Store Reviews
AverysMommy313, 5 stars:
I use the app every day. Whether its with my chemex or French press. It's perfect.
I love the detail it goes into with each specification, and the walk through process of the brew. It would be 5 stars if you add more brew styles (like Kalita Wave) and how many intervals you pour in (or a constant pour as compared to a pulsed). very useful for a brew geek.
