Search any food and see what it equals in walking, running, cycling or swimming — personalized to your body. Free forever.

Hey Product Hunt 👋 I built UndoCalories because calorie numbers often feel abstract. Seeing “563 calories” does not always mean much, but seeing “around 140 minutes of walking” makes the impact easier to understand. UndoCalories turns food calories into exercise time across activities like walking, running, cycling, and swimming — personalized to your body. The goal is not guilt, dieting pressure, or obsessive tracking. It is simply a clearer way to understand everyday food choices. I built this as a solo maker and I would really appreciate your feedback on: - whether the idea is useful - whether the results feel easy to understand - what would make you come back and use it again Thanks for checking it out.

A nice tool for quick reference, though it would help to add a history tab so you can see what you've searched over the week and notice patterns in what you're eating versus burning.

@mira1455108 There's a History tab that shows your past searches and food-vs-burn over time once you're signed in (free trial, no card). Would love your take on it if you give it a spin 🙏

searched a bagel and it told me i'd need to bike for like 40 minutes which is honestly the wakeup call i needed

the wakeup call i needed" — honestly that's the whole reason we built it 😄 bagels are sneaky. thanks for trying it!
