Introducing RoastWatch, an iOS app for Roasting Coffee

roastWatch banner

For long time readers of the Compass, you might have guessed that we enjoy participating in every step of the coffee process, including roasting. After I began getting into iOS app development, I started searching for a project to cut my teeth on. That project is RoastWatch.

RoastWatch, a portmanteau of “Roasting” and “Wristwatch”, is a simple, yet powerful iOS tool to help you track and log your coffee roast profiles. It was designed visually to be an extension of the iOS operating system and functionally as an extension of the stock iOS stopwatch app.

RoastWatch is a simple, yet powerful iOS tool to help you track and log your coffee roast profiles.

The UI elements will feel familiar to the iOS stopwatch, while built with more powerful time/event logging features.

99 Problems But a Probe Ain’t One

RoastWatch was built for the dearly beloved “probe-interface”-less roasters of the world. With the “record” button and the temperature control panel, logging temperatures with associated times is easy, especially if you don’t have a probe to interface with fancy roasting software. RoastWatch also allows you to record custom events while you’re roasting. You can build a custom event list to quickly mark events during roasting while maintaining consistency from (space ghost) roast to roast. Adjust your temperature logging preference under the “Settings” menu for either Celsius or Fahrenheit.

Charting and Data Logging

You can save all your roasts and search them later. Pictures and Names associated with roasts are editable. RoastWatch also charts your roasts in real-time, or at least as real-time as it gets without a thermocouple probe attachment! Record events while roasting and easily slide the temperature scale. After you have completed a roast, v1.0 export options include email or exporting via .csv (for importing into excel or Google drive etc.).

Conclusion

Development for RoastWatch has been simply awesome. It’s been both fun and challenging to work on something that is going to help the roasters of the world track and share roasting profiles. I hope to answer questions you may have, and hope that you strongly consider sending me feedback. The app is $3.99 USD in the US App Store. Why isn’t it free? Well it essentially comes down to that I want to be able to cover my developer costs and the time I’ve spent on RoastWatch, while acknowledging that the market for coffee roasting apps/tools is, I believe, quite small. That being said, I think you’ll enjoy using it as much as I’ve enjoyed developing it. Version 1.0 is available as an iPhone app only, but I am hoping to definitely port it to a more iPad friendly version in future releases.

RoastWatch was developed by Darren Jennings, Co-founder of The Coffee Compass.

  1. Thank you for “…maintain consistency from (space ghost) roast to roast.”

    • Ditto on that.

      And congrats on completing what looks like a nifty app.

      I’ve been roasting and logging in databases on my phone since the open source HanDBasE community contributed a home roasting schema over 10 years ago.

      Over that time, I’ve been been surprised how little the temperature details and profiling came to matter to me in actual practice. Mostly because the seasonality of greens rendered more thorough details irrelevant — i.e., because before I could dial in on a coffee much further, I (it) was out of stock.

  2. Let us know when it’s ported to iPad.

    • Ryan, I’m glad you’re interested in an iPad only version. I’ve tested it out on the iPad, downloading the app as “iPhone only” and I did not lose any functionality. Of course you would be emulating an iPhone, so it will just feel a little clunky since it won’t be utilizing the full resolution of the iPad. I’ll send you a free code to your email address to redeem the app and you can try it out. I hope to make an iPad only version in future releases.
