User reviews

can’t save my profile

I can see profile saved message. but its not!

Dear Creator

I’m really enjoying using it.
As a dedicated Sandbox Roaster user, I’d like to share a few suggestions.

1. Shorten feedback latency for ROR, temperature data, etc.
The current data refresh interval feels a bit long. Near-real-time updates would make precise control during roasting much easier.

2. Release a dedicated PC software version
Adding a PC desktop app alongside the mobile version would greatly enhance the roasting experience with larger screens and more accurate input devices.

3. Freemium model restructuring suggestion
Keep advanced profile features paid, but:
• Remove limits on profile comparison and storage
• Fully enable profile sharing
Opening core features for free in this way would boost collaboration and network effects, significantly growing the overall user base.

Captive App Frustrates

Lots of problems. Here we go. (1) Only way to use their roaster is to use the app. The stock roast profiles are meh. They make you pay for their more advanced profiles (robbery). As you learn their roaster and try to understand their more advanced paid for profiles, they purposefully do not let you see their power/fan/drum speed settings, making it harder to learn and love their machine. Makes me want to throw it out and buy a more open roaster. It’s as if they feel like they need to pay for their software developers through subscription fees when they should sell more overall devices and become a bigger share of the home roasting market. Their strategy limits adoption given bad reviews of their customers (2) The app design is poor. Some screens force landscape while others do not allow landscape. Their users want landscape on all forms, but they haven’t resolved in the years the app has been out. Editing profiles are way too hard. Trial and error is how roasters work. It should be incredibly easy to just move control points around on a touch device (it’s not). Figuring out how to get to the screens to modify the past roast profile and edit is convoluted. Honestly, the app needs a tear down and redo it’s so poor.

Buggy version 3.8.0

Once the new version has been released, the roasting doesn’t start: it shows an hour glass in the app and nothing happens
