Napkin Math

amazing :))

Really like the non-calorie-counter angle here. Food tracking is much easier to stick with when it feels like a journal, not homework.

How accurate is it at estimating portions and ingredients from a messy real plate?

How does it track seasoning and sauces in dishes? Also can you upload workouts to the app to help evaluate your meal intake?

Congrats team! The focus on privacy and non-judgmental tracking will probably encourage more consistent use.

Photo-logging is the smart call here, because what kills food journals isn't motivation, it's friction... by day 4 nobody wants to type "grilled chicken, 180g" into a database. I build a habit app, so the moment I always come back to is the missed day. Someone logs for a week, skips three days, feels guilty, then quietly ghosts. What pulls them back, does the coach reach out, or is the "cute enough to share" part doing that work?

I love how simple and approachable this feels. Most food tracking apps can be overwhelming, but taking a quick photo is something people can actually stick with.As someone managing PCOS, I can see how helpful this could be for building awareness around food choices without the stress of manually logging every detail. Making the process easier and more enjoyable is a huge win for long-term consistency.

You’re leaning into a “Strava for food” social vibe—what have you learned people are comfortable sharing vs keeping private, and what guardrails (privacy controls, defaults, anti-comparison design) are essential to keep it joyful and non-judgmental?

Your app feels like the opposite of every fitness product that makes people feel guilty for eating. That alone makes it memorable. I can imagine teenagers using this causally while still building healthier habits without even realizing they are tracking nutrition.

Just downloaded it and it's so cute. I'm very in the fiber maxing zone but I'm curious to know how well it works with Indian food. I already like that I have a voice entry feature cos I've been using gpt for it and get too lazy to create an actual GPT. I also like that I can tell it exactly how I want to track my nutrition and the different data points I want to take into account - where I am in my cycle, track my habits over a week, where my energy rises and crashes, log recipes so things can be repeatable, reminders to check in, track the time when I eat my meals and how to optimize that, and also when I work out. it makes me feel in control.

The photo-first approach is the smart part here. Most food trackers die on manual logging friction. I work on voice AI for older adults aging at home, and the same pattern shows up: any logging step that takes more than a few seconds just doesn't happen. Curious how Napkin Math handles foods that are hard to read from one photo, like a mixed home-cooked dish or a drink. Does it ask a quick follow-up, or infer from context?

First off, I'm obssesed with your design. It's so fun, so refreshing, and really represents your "food is joyful" motto. Not a designer, just a user tired of the 'corporate minimalism' that at some point was everywhere (thankfully, it's improving little by little). On the actual nutrition side, it's really cool how your approach isn't weight loss/tracking calories. I'm an MD in a nutrition residency and getting people to actually track everything is such a challenge, even when they have extreme symptoms like you did. Often all you get is a list of meals, no portion, no preparation method, not even all the spices and sauces they used specified. Napkin Math seems like a great solution to that. My question is - you seem to be very focused on people helping themselves (with the help of AI). But do you plan to eventually make this available to healthcare providers? Plugging it into existing nutrition software or creating a provider portal where the physician/dietitian can follow multiple patients, look at patterns, look at medications taken, too (because in many cases people are on medication, often medication that can also cause GI symptoms, and we'd want to track that) would be really cool.

Nutrition tracking is for everyone.A year ago, I suddenly had an intense stomach pain. My husband rushed me to the ER, where they gave me opioids and ultrasounds. And then I was handed the list. The list of food triggers, that covered 80% of my regular diet. I needed to track everything I ate, when I was in pain, and look for patterns.So I went home and searched where I thought there would clearly be a solution: the app store. But I was shocked to find, that since my time in high school, food tracking was still only narrowly focused on calorie deficits.That's why we built Napkin Math.A nutrition tracker built to be hyper-personalized to your health goals. It feels joyful, social, and playful. All the while, your data works for you and supports you on your personal health journey. Think "Strava for Food": you log, you learn patterns, and you do it alongside your community in a beautiful journal.We'd love your feedback! What's worked (or really hasn't) for you and food?
