Every tool on this site runs entirely in your browser. There are no accounts, no tracking, no ads, and no data sent to any server. Your recipes and numbers stay on your device.

We built these tools because we kept Googling the same conversions, scaling the same recipes, and guessing at the same serving sizes. Now it's all in one place — fast, free, and designed to actually look good on a phone while your hands are covered in flour.
