    This sophisticated and minimalist smart scale brings new heights to connectivity - it's the world's first dual bluetooth scale! JIMMY has a detachable magnetic display bar that connects to the weigh scale via bluetooth and at the same time connects to the companion JIMMY App (available for iOS and Android). You can even control JIMMY with your Apple Watch!

    Place the display bar anywhere you want thanks to the handy magnet on the back. Put it on the side of your espresso machine or anywhere else at eye level that a magnet will stick. By separating the display, Hiroia created a highly water-resistant, heat resistant scale that fits comfortably on a drip tray, all while making it easier to see the timer and weight measurement. On top of all that, the display is easy to use in any light condition - it's super bright and designed so you can read it from any angle.

    JIMMY has customized modes for both pour-over and espresso, switchable with a gentle touch. And the JIMMY App has four different modes to bring out your inner coffee geek. Espresso Mode to record and save your brews or espresso extractions, Pour-over Mode where you can follow a recipe, Training Mode to practice your pouring speed, and JIMMY Mode for simply controlling JIMMY and displaying the real-time data.

    The best part about JIMMY? It can easily be updated and upgraded through the JIMMY app. And there's enough memory in JIMMY for some serious upgrades.

Mixed feelings

Well, lets just say that if I had paid full price for the Jimmy, I would have been extremely disappointed. At almost half off full price, it's just passable.
Of course, the most compelling reason for choosing the Jimmy was the detachable display (it just suits my workflow). However, once detached, the display will not pair with the scale. So you must reattach it to the scale every time you turn it on; this is a significant compromise.
In addition, despite multiple attempts, I was unable to pair it (Bluetooth) with my Android phone. It did pair with my iOS device however.
I chose this unit over both Acaia models because of the detachable display and the size which is right in between the Pearl and the Lunar, making it very usable for espresso and pour over. It's accurate, fast and feature rich.
But the bad implementation of many of the features make me question my choice.

Hey Daniel! Sorry that you are not enjoying the Jimmy as much as you hoped. We love the detachable display, but to activate both of the sides it does need to be attached else the weighing plate would always be 'on' and work the battery down very quickly. We have definitely got used to re-attaching the bar to switch on and now hardly notice it - hopefully you will feel the same after more use. Regarding the android pairing, the firmware has been updated several times so, if you haven't already, please update the firmware via the app. However, if it's still not working for you, please reach out again and we'll be happy to assist. Thanks for the review! Wes

Undoubtedly this scale is a beast! Incredible responsive and accurate, and has great feature, specially for espresso, of detaching the display. However there are a few down point that I found so far that I’ll be listing down bellow:

1. It’s pretty luxurious and well build, but it’s full metal construction make it a bit heavier than others.

Comments about the App.

2. There isn’t a way to save a template pour over recipe to use it every time I want to brew a coffee without designing it all over again. I noticed I can save a recipe after using it to brew a coffee, but this way I would be saving the results, which might be very different from the original inicial recipe. I’d like to save the inicial base recipe to try replicate it, or give it to my baristas for them to make it as I designed it. In that case saving the results wouldn’t be helpful if the results they had were wrong or different from the inicial recipe.

3. It’s not possible to edit the count down time in the “pour over mode”, so it would start counting down the desired time from the first beginning I started adding the water in the blooming fase. Since the coffee already started brewing and extracting from the second the water touched the grounds it would be more reasonable,in my opinion, for the timer start from this point, instead of start counting down only after I finished pouring the blooming water. In that way, the blooming would have around 50s (depending on the chosen flow rate) not “30s” as I first designed.

4. For some reason, on the results page after brewing a pour over coffee it shows a number of “pause” fases during the brew that didn’t happened, since I chose to do a single 5g/s pour and didn’t stop the flow rate in any moment until I hit the water target.

I hope in the future Hiroia will release an update correcting this programming mistakes and also add more customizations. Other then that the App it’s incredibly responsive and has near zero delays and the scale is a...

Hey Lucas, Thanks so much for the feedback. We agree that this is a great scale but a few idiosyncrasies in the app are frustrating. We constantly work with our suppliers to keep improving their products and we will be sure to pass your valuable feedback on to influence future updates. Thanks again!
