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. ### 4/5 — Need help *2023-10-11* Hello, I have a question: Wenn I make a Copy of a Roast,I always have to bind the Probst again to the sensors. how Can I Copy a roast including the Data Curve? ### 3/5 — Update? *2022-01-06, version 14.0.0* 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 ### 4/5 — Like the full suite of Office *2021-08-02, version 14.0.0* 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?!? ### 4/5 — HB烘焙机可以用吗 *2021-02-24* HB自带的温度计有蓝牙通讯，不知道能不能兼容这个软件，不知道怎么设置 ### 4/5 — 终于更新了 *2021-01-15* 比较难上手的烘焙软件 ### 4/5 — Great app - with one bug. *2019-07-02, version 11.0.0* 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. ### 4/5 — Overall good app *2019-02-03, version 11.0.0* 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. ### 1/5 — Linguage *2017-04-11* Preciso de linguagem em espanhol... ### 5/5 — Always one step ahead *2017-02-07, version 10.0.0* The latest updates are great! The app is designed by a roaster for roasters and it shows. ## Most critical reviews (10 lowest-rated) ### 1/5 — 开始圈钱了 *2026-08-12* 之前用了好几年，挺好用的，虽然app要花钱，温控探头要花钱也可以接受，现在不充值不给你烘焙了，一年快3000块，之前下软件就交了一次费用，现在还想骗钱？ ### 1/5 — Stealth switch to subscription *2026-08-10, version 26.0.0* I paid money for this app and now it suddenly switches to a subscription only service? I won’t be subscribing and I advise you to find another app to use. It is not that good. ### 1/5 — Subscription??? *2026-08-08, version 26.0.0* I purchased the app with no mention of limited functionality and no mention of a subscription. Now I can’t use it without paying more than I was originally told. I hope the developer reconsiders his business model and grandfathers existing users. ### 1/5 — Charge you for the app and then hit you with subscription *2026-08-07, version 26.0.0* Been using this app for over 8 years. Updated today to find no longer usable without buying into tiers of subscriptions. Long time users are being locked out. ### 1/5 — Paid for the initial app years ago. *2026-08-07, version 26.0.0* After close to 2000 roasts, they change up and want me to pay $4.99/mo. No way! There are way too many free coffee roasting apps out there that do the same and perhaps better job of clocking roasts. Thanks but good bye! Too overpriced! ### 1/5 — Long time user, priced out *2026-08-07, version 26.0.0* Sad to leave, but I’m not going to pay for a feature that was previously free. Can’t print a label now without subscription. Sad times. ### 1/5 — More $$ after the $10 purchase *2026-08-05, version 26.0.0* Been using Roastmaster since 2010. Updated today, and it’s no longer usable without buying entitlements. You should have released a new app instead of bricking the app for long time users. ### 1/5 — What’s with the update? *2021-01-17, version 14.0.0* Was a great app, not too sure about this latest update though ### 1/5 — 三豆客500g机子无法连接蓝牙探头。 *2018-08-14* 购买了以后连接不上，说无法连接云端，找了苹果公司说是私密。app售后完全不知道怎么联系 ### 1/5 — 真是晕死 *2017-04-17* 软件闪退，没法用 ## Most praised reviews (10 highest-rated) ### 5/5 — Great App and so feature packed *2021-03-25, version 14.0.0* I recently upgraded my roaster and wanted to use my ipad for tracking roasts. I took gamble on this app as the reviews are so old. What can i say it’s fantastic, i have purchased a ThermaQ Bluetooth temp unit. Setup was very simple and had probe readings up and running in minutes. In terms of functionality its huge, i have all my green beans stored and tracked plus each roast has huge amount of data against it. Its a complicated program so you need to spend bit of time learning and the webcasts are great plus the help files built in to the app. If you are into your roasting and want an app to log and track everything to do with on your ipad this is the one. Great app thanks ### 5/5 — Solid and reliable *2021-02-22, version 14.0.0* We’ve roasted nearly 8000 batches using this app. It rocks. ### 5/5 — 簡體中文版 *2021-01-28, version 14.0.0* 已經更新到最新版本，而且又是中文的，更容易使用，就是使用分享的人太少了 ### 5/5 — Amazing roasting app! *2020-10-22, version 11.0.0* 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. ### 5/5 — Essential home roaster tool *2020-05-29, version 11.0.0* 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. ### 5/5 — Great, well designed, modern app *2020-04-30, version 11.0.0* 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. ### 5/5 — Fantastic! *2019-03-09, version 11.0.0* 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. ### 5/5 — Great roasting App *2018-07-15* We have logged thousands of roasts on several different roasters using iPads bluetherm duo’s and this app... it works extremely well with lots of things to tweak behind a relatively simple interface if you so desire... ### 5/5 — Great App *2017-04-19, version 9.0.0* 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. ### 5/5 — How change language??? *2017-02-19, version 10.0.0* I want Chinese or English!!
