    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.

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!
