Essential home roaster tool

Tool is very helpful in tracking my roasts and creating consistency in my output. I must also say that Danny has incredible to work with. Great developer and professional support! Have a cup of coffee and catch your breathe.

Great, well designed, modern app

I avoided this app for a long time because I *wrongly* thought it was dead and from the iOS 6 area of skeuomorphism. Screenshots on their website are dated, the roaster graphic threw me, along with infrequent updates. I finally bought it today on the verge of writing my own app, and oh boy am I glad I did! I’ve really been missing out for a long time. It’s well thought out, feature rich, and works very well. If you home roast, and don’t want to use Artisan, this app is a must have. I have a Behmor, and it has custom profiles just for that which is great and niche because I can’t easily put probes in there and the automatic modes are already profiled.

Great app - with one bug.

Great app! Love it. One issue: turning on the iOS setting “Increase Contrast” obscures the description for all Preference settings. Sorry for posting bugs here. I didn’t want to create an account on the forum.

Top notch software and invaluable to a home roaster. I think this would be my most missed app if an os upgrade ever broke it. Please keep up the great work on this.

Overall good app

I’m new to roasting but I started using this app to document my progress and results. Quite satisfied with its capability. Since I’m using a Behmor 1600+ I don’t have an easy way to log bean temperatures but I can log the basic B reading for comparison purposes. Help files are full of great documentation. If I had a wish list it would be for two items - ability to store a low to medium resolution image with a roast, and the ability to make a blend from existing roasts.

Great App

I have been using RoastMaster for nearly two years and can't imagine roasting without it. Stat is transmitted to the app on my iPad via Bluetooth. The app provides consistency and milestones to help me roast the way I want. It also tracks inventory, cuppings, scores, ratings, etc. I have created curve templates so I can follow a precise roasting profile and modify it as desired. Very full featured and highly recommended.

I fully agree that both the app and Danny are extremely helpful. It is really comprehensive in covering so many aspects of roasting coffee. But there is one feature that really brought me back after a year or so of using it, then a couple of years of not using it. It now generates, DURING A ROAST, a curve of any reading or setting that one wishes to time plot. In other words, at any desired moments, one can enter data that are read from any source, and the data will be graphed vs time. That is great for observing the progress of, for instance, beand mass temperature. (But you could also use it to generate a time plot of the outdoor temperature, if you so wished, though I haven't checked for the upper time limit on such a plot.) Some roasters spend a lot of time and money on fully automatic roaster control from their computer. This is for the simpler person like me who wishes to do things more manually, and get a nice 'feel' for things. It is also helps remind those like me who need to do certain manual things during a roast, but sometimes miss because of inattentiveness. I like it!

I started using Roastmaster as a hobbyist, and have continued with it as I transitioned into a small business owner/micro-roaster. And this app has performed exceptionally at every step of the way. The developer is a roaster himself, a coffee industry professional, and a talented app developer...and all-around great human! I can't say enough good things about the app and developer. Tip o' the hat!

Not worth the cost

This app has its usefulness, but it is not worth the $10 I paid. It has a very non-intuitive feel, and features seem to change with no warning or pattern. Sometimes I am able to compare a current roast profile with a historic one, but then that feature drops out mid-roast. For the cost, I expected much more.
By Jpinec

Very useful!

I have been using this for years and I love it. Any chance of an iwatch app coming for manual data logging?
