A simple, beautiful food diary that helps you understand your eating habits over time. Stop counting calories and start seeing the bigger picture. Log meals easily, build a record you can actually keep, and turn everyday entries into patterns, trends, and insight when you need them.
EASY TO KEEP
Log meals in a way that fits real life, without turning every bite into a chore. You can snap a pic or just describe what you remember. Easy enough to actually stick with, day after day.
SEE THE BIGGER PICTURE
The value of a food diary is not just what you logged today — it’s what you start to notice over weeks and months. Napkin Math helps you zoom out and see bigger-picture patterns in how you eat, so you can better understand your habits without obsessing over numbers.
UNDERSTAND HOW YOU FEEL
When you feel off, your data is there to help you look back. Ask to find out patterns related to symptoms, energy, appetite, digestion, or other shifts in how you feel. A simple place to start connecting the dots between what you eat and how you’re doing.
SUPPORT GENTLE CHANGES
Napkin Math can also help when you’re trying to move in a direction, like eating more protein or being more consistent with meals. Instead of forcing you into a rigid plan, build awareness over time so you can make changes that feel realistic and sustainable.
BEAUTIFUL & SATISFYING
Logging should feel good. Napkin Math is designed to be clean, pleasing, and satisfying to use, so that coming back to it feels natural. It’s a food diary you’ll actually want to open, whether you’re logging a meal or reflecting on your day.
NOT A CALORIE TRACKER
Built around awareness, curiosity, and useful reflection — not punishment, perfection, or calorie counting. Focus on intuitive eating and enjoying your life while feeling healthy.

I’ve been using Napkin Math pretty early on and it’s been fun documenting my food, sharing with friends and learning more about nutrition! I’ve used other apps in the past, but this app makes it fun by transforming your pics into cute cards and provides a ton of context to your nutrition across days, weeks or months. I also love how they have a chat feature that can help you talk through anything related to your food logs, making it super easy to discover data/trends on what you’ve been eating. Obviously it’s a new app and is still growing, but the devs are super responsive and are opened to all sorts of feedback! I’m definitely sticking around

So cute
Perplexing glass
I haven’t run through all the possibilities that this app has had to offer yet, but I can go ahead and vouch that it is an adorable way of keeping track of the food you eat. A very easy process of choosing a meal each day, taking a picture, and the app does the work on separating the main dish from the background. Once you have done it enough days, seeing the grand collage of what I’ve had the past month I considered to be very entertaining and a great way of being mindful of what I have over the next few days. Definitely saves me from having a bunch of photos in my camera roll!

My Dream Food Tracking App
elaineheheh
This app has all the features that I’ve wanted in a food tracking app plus social aspects. I was previously using chatgpt to estimate my macros and calories, but this app helps organizes that data while still having the ease of AI. I like the timeline view of each day, setting goals, and being able to see what my friends are having. There are a few bugs like some pages will crash the app, but the app is relatively new so I’m sure the developers are working on it.

simple to use and customizable

I love that there’s so much variety with what goals you can set, definitely good for people who aren’t just trying to lose weight or max out on protein. Also one of the only times where I have felt like AI actually added to the experience (by analyzing your food pictures and giving you really good nutrition estimates). Otherwise, you don’t really need to talk to a chatbot at all. Very cute layout and made me excited to log my food !
