## Roastmaster Reviews in United States

### ****- "Needs update and more support"
I’m super excited to try this out, it is feature packed and looks intuitive. The main problem I have is that it’s a bit dated, iOS 14 vs current iOS 18 and the support for cheaper, off the shelf Bluetooth probe thermometers (ThermoPro) is nonexistent.
-- rantmakes, 2025-03-09

### ***-- "Update?"
This app has the capability to be a great app for roasting if they update it. If you have a Behmor 1600 and only use single origins your good. I can only inventory my single origin beans, wouldn't let me list my blends that are from multiple origins. So far this is a waste of $10
-- Mike Rothwell, 2022-01-06

### ****- "Like the full suite of Office"
Except for coffee! And like the full suite of Office, I only use about 5% of what’s offered! I log inventory, roast times (nose, eyes, ears mainly) but overall, a useful tool for a roaster business. If there were just one item I’d like added, it would be the development percentage added to the roast screen! My mental math, converting the mins/secs to hit 25-30% DT is just too much every roast! Since dev time is a percentage function, why not add it?!?
-- Droo16, 2021-08-02

### ***** "Amazing roasting app!"
I tried all the major roasting software apps/programs. I used Cropster and Artisan extensively and came back to Roastmaster. The scope is pretty much one of the best you can use and it has all the features you could possibly want! 
I just hope they push an update before apple makes it redundant.
-- Marginal Man, 2020-10-22

### ***** "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.
-- BVC Roasters, 2020-05-29

### ***** "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.
-- hannibal87, 2020-04-30

### ****- "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.
-- picree, 2019-07-02

### ***** "Fantastic!"
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.
-- maitri1, 2019-03-09

### ****- "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.
-- pj47tech, 2019-02-03

### ***** "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.
-- Lbdina, 2017-04-19

### ***** "Retired"
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!
-- Bats & Crows, 2017-02-04

### ***** "Essential"
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!
-- Coffee Roaster Small biz guy, 2016-09-29

### **--- "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.
-- Jpinec, 2016-07-05

### ***** "Very useful!"
I have been using this for years and I love it. Any chance of an iwatch app coming for manual data logging?
-- CaptBrwnStubble, 2016-04-08

### ***** "Must have app for roasters"
When I started down the journey of coffee roasting, I was using traditional paper logs. But I'm an iOS person and I wanted an app to log my roasts. This app is perfect. I'm still digging in to all the customization and info that it can hold and, with every update, it just gets better and better.
-- SixStringBuzz, 2015-11-04

### ***** "If you roast- you NEED this ap! UPDATE!"
I wrote the first review for this app when it was released, and just did my 303rd roast with it. The features just keep getting better! Keep up the good work! Here's my initial review, for grinds and grins! ☕️
I was sitting at home this morning meditating on the full city+ Sumatra I roasted last night thinking, you know, I should make an app that let's you keep track of your roasts, so you can duplicate the art you just created the day before. I, however am not the programming type, so I figured I should see if there was "an app for that". Indeed, there is! This program is a must for any serious roaster. The UI is polished, and shinier than the finish of a French Roast out of the oven. It let's you track what kind of beans you have, how you have roasted them in the past, cupping scores, and stuff I never thought about, in a simple to use way. Now I can stop using my iPhone timer to keep track of what I consider vital information. Keep up the good work! And thanks for nit releasing a half-baked app!
-- Neo442, 2015-10-28

### ***** "HUGE update!!"
Thank you! ❤️
-- jcw5002, 2015-09-25

### ****- "A Must for Any Roaster"
This is a wonderful app that has doubled my toast quality and made made roasting coffee even more fun. It is very deep and very customizable. At the same time, it is easy to use even when your in the middle of an intense roast session. 

I roast with my grill and a drum so I have to manually enter my curves. It is very easy to do and that's not something most roast software devs have accomplished. I also love the variety of data you can enter which makes it perfect for those that take this science/art seriously. 

There are a few things I'd like to see improved. Mainly, the graph is a bit hard to read. Despite the customizability, it can get very cluttered and the dark background makes it hard to decipher. Here are a few other things in the roast section I personally feel could be better:

- Easier to read graphs
- Can change minimum temp of graph -- not just 0
- section for moister loss percentage 
- section for development percentage 
- section for preheat temp
- ability to hide unwanted sections (like agtron or roaster voltage)
- it should remember or save curve names and parameters when adding a curve
- in the bean inventory, it shouldn't go into the negative numbers. Just 0.

Otherwise, this is an amazing app that I'll continue to use as I develop my roasting skills. Great work!
-- Musicbender, 2015-04-05

### ***** "Now a vital part of my roasting"
The hardware portion was a little intimidating, but after installing Phidgets hardware and connecting it  to my Diedrich IR-12 it just works. So all I do is use the software and haven't given the HW a second thought. As it should be. 

Profiling my roasts is automatic now. With the ability to zoom in I can see trouble coming and adjust if necessary. The delta curve tells me more information than just the temp curve. The ability to save roasts as profiles makes repeating a roast much easier. You can even cup and score your roasts in the app. 

All kinds of features are customizable- the delta curve size, how data is presented in the analyzer, when control points are recorded. I keep learning more about it as I dig deeper. The developer is responsive and genuinely interested in making the app work for all of us, home or biz roaster. 

The Dropbox integration is nice. I noticed if I pass a database back and forth via Dropbox it sometimes comes up as the old version. This maybe a Dropbox issue, quitting both Dropbox and RM and then sending the database over seems to get it right. 

My only gripe is that data entry could be simplified. Like sliders for cupping scores, data points that are numbers and such. 

This app is now an integral part of my roasting day. It's my living. The app has paid for itself and the hardware since day one. Thank you for making my life so much easier and my coffee so much better!
-- AZRichG, 2015-03-02

### ****- "Excellent for home coffee roasting"
I recently upgraded from an air popper to Behmor 1600 Plus for home roasting. I wanted better logging than paper for repeat ability and tracking. This app fits the bill. I've logged a couple dozen roasts and am pleased with the results.  The only woefully absent feature is database syncing via iCloud or Dropbox. I don't always have my primary iOS device on hand and would love the ability to log a quick roast using my iPhone. Overall, well recommended.
