I was about to return my new opus until I came across this app! ### 5/5 — Prefect *2023-06-27, version 1.2.0* Helps a lot, well designed ### 5/5 — Must Have For Opus Owners *2023-04-22, version 1.1.0* I love being able to tweak and save different grind settings depending on my brewing method. ### 5/5 — Great Buddy App for Opus *2023-04-04, version 1.1.0* Well done, definitely makes it easier to track grind setting for different brewing methods! My only addition would be to make it so your saved brewed methods could have the titles changed or make it so you can add more. Just in case you have a bunch of different beans you want to go back and forth with. ### 5/5 — Amazing app *2023-03-24, version 1.1.0* Makes dialing in the Fellow Opus way easier! No more complex math, spreadsheets, or sticky notes. Super easy and fun to use - THANK YOU! ### 5/5 — Life Saver *2023-03-06, version 1.1.0* Works perfectly. ## Most critical reviews (10 lowest-rated) ### 2/5 — Lost all my data! *2025-02-05, version 2.0.0* Great app for helping to dial in on quite a confusing grinder but the latest update wiped out all my saved data. This is super annoying! ### 2/5 — Buggy *2023-08-20, version 1.2.0* Just downloaded. Really buggy. Coffee screen won’t open. App seems to freeze. Unusable. ### 3/5 — App data deleted in recent update *2025-02-03, version 2.0.0* This app has been super helpful, but after a year plus of storing the different beans I’ve been trying I find this morning that the app was updated and all of my stored data is gone. What a huge bummer. ### 4/5 — Noooooooo! (But, okay I get it) *2025-02-09, version 2.0.0* You wiped all my saved brews and grind settings!!! Edit: oh it’s the last thing mentioned in update notes, not shown in the App Store’s preview. :-/ Otherwise a brilliant app. No ads. Simple to use. Design complements the Fellow grinder. I use this daily, and saving different bean sources means no fiddling to dial in grind when I get a new bag. Again, no ads • a passion project for the developer and a gift to Fellow grinder owners. We need more like this on the App Store. ### 4/5 — Noooooooo! *2025-02-02* You wiped all my saved brews and grind settings!!! Edit: oh it’s the last thing mentioned in update notes, not shown in the App Store’s preview. :-/ ### 4/5 — Thanks! *2025-01-31, version 2.0.0* Thank you Tim. Love the app and the design. Newest update 2.0.0 however deleted all my saved coffee settings 🫠 CoreData? ### 4/5 — Does what it says on the tin. *2024-10-24* It’s a convenient tool for not having to figure out the opus’ grind settings. The configure brew button does nothing on my device at least but I can just write this stuff down on paper. ### 5/5 — Thank you! *2025-10-02, version 2.0.0* This app is a great way to organise and level up your coffee game. A must if you own the Opus. ### 5/5 — Nice to have *2025-07-11, version 2.0.0* This a great app that does exactly what is says. Love the UI, clean, elegant, and no ads. I wish I could do shot journaling too. ### 5/5 — The best thing I didn't know I needed *2025-01-17, version 1.2.0* Thank you to the generous developer who did this public service to all of us with this great (and confusing) grinder. One of the best-scoped and thought-out free apps I've seen in years. Thank you 🗣🗣🗣 ## Most praised reviews (7 highest-rated) ### 5/5 — Just what Opus owners NEED *2024-12-15* Awesome app, thank you. Does one simple function and does it elegantly. Lets me understand the relationship between the adjustment rings, and record a single unified grind value for various beans. I only wish that the saved beans and values would sync across my devices like Living Earth syncs my saved cities. Willing to Beta test for you. ### 5/5 — Game changer for this grinder *2024-12-14, version 1.2.0* Once I receive the fellow opus I regretted it because of the difficulties understanding the grinding ratios for espresso. This is a game changer for the unit and would not keep it if this app to not exist. Thank you i hope feellow knows they owned you one or five ### 5/5 — Fellow Opus Companion *2024-06-16, version 1.2.0* What an incredible app to go along with a grinder that doesn’t have its own app created by the company. I can finally understand how to use my machine and inner ring! It also helps with telling you the microns size of the grind! You did a fantastic job matching a beautiful UI to Fellow’s aesthetic. I wish they were paying you to create an actual decent app for their Stagg Kettle so I could use my phone to check on it! Either way, cheers to you for making this a free and very functional app. So incredibly helpful and makes my coffee life so much easier. If you had a donation link of any sort, I’d love to contribute a little just to say thank you! (No ads anywhere is just icing on the free cake!) Thank you for this, truly! You’ve made this grinder a much better experience to own. ### 5/5 — Saved a lot headache *2024-05-21, version 1.2.0* Thank you, use it every morning. Happy brewing ### 5/5 — Excellent to Dial In! *2024-02-27, version 1.2.0* These app helped me a lot with my fellow opus, it’s excellent to dial in and understand the outer and inner burr grinder settings. if you want to understand better your fellow opus you should download this app ### 5/5 — Excellent Opus Companion *2023-12-28, version 1.2.0* Must-have companion for the Fellow Opus. Simplifies the workflow and allows for repeatability when switching up brew methods. Super intuitive UI that makes sense of a wacky grinder. To put this out there for free without ads or tracking is incredibly generous. Thanks a ton! ### 5/5 — Perfect! *2023-12-24, version 1.2.0* Thanks a million for making this! I’ve loved my Opus for my Aeropress and now moving into the espresso world. I was feeling a bit overwhelmed by the transition but then found this app! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
