### 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.

### 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.

### 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!

### 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!

*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?

### 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 🗣🗣🗣

### 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
