I don't feel like calculating how much I poured into a cup every time, or manually journaling every time I get a drink. But it would be nice to know how much soda I've had in a day.

The only reason I can think of is the listed nutritional value isn't always accurate. Maybe I'm wrong, but I don't understand how this cup can be any more accurate than the label.

Honestly if I wanted to count calories and monitor my nutrition, I would rather speak to my phone what I'm currently eating and have it tally everything up. And I would gladly pay $10 for an app like that over $200 for a cup, so until someone can bring this technology down to $20-$30, I don't care.

Wine.

Wine connoisseurs would probably scoff at drinking out of a giant cup. There's a whole art/science to the cup shape and ritual of drinking wine.

Not just connoisseurs, but also most people who drink wine semi-regularly.

All due respect to them, I'd like to know how many carbs are my wine. If this device can do that, it's the only possible reason I'd buy it.
