It works but doesn't allow for any custom programming or the ability to save recipes. I used it for a 34oz French press and the app says to pour 905 grams on the second pour and the press has a Max fill line at 715 grams. If the app had more functionality I'd give it 5 stars.

Similar to other reviews, the quantities of water (measured by weight via the scale) called for don’t line up with what actually fits in the carafe. If you actually try to follow the instructions, the water enters the spout and overflows once the lid/plunger is placed on top (without plunging). Not sure what would be the best way to fix this, and strikes me as a result of not testing out in the real world the quantities called for in the recipe.While the above is frustrating, it’s not like I don’t know how to make coffee at all (though perhaps I’d hoped for a better coffee making experience), but what’s even more annoying is that it consistently auto-tares when an object is first placed on it while trying to use the scale just as a normal scale. Why? The app already has a tare button, which would be easy enough to press if I need to tare the scale. It feels like a poorly thought out attempt at helping the user when it really just ends up limiting what the scale can do literally—it shows the weight for a split second before auto-taring, meaning this is a software issue that would not take much effort to resolve.

This app and scale combo would be greatly improved by adding the ability to enter custom amounts of water and give the ability to scale the recipes accordingly. As it is unless you’re brewing a preset amount (ex. Hourglass settings are only 16, 20, 24, or 28 oz.) you’ll need to do some additional math to get an accurate recommended amount of grounds.

After a little over a year of using this scale, the app completely broke, but who ever is the developer fixed it. Not my favorite scale but it works well
