Kilo

Look, we get it. You’ve probably tried a dozen nutrition apps already. Most of them feel like they were designed by someone who’s never actually tried to log food while standing in line at lunch, squinting at their phone.

We built Kilo because we kept running into the same problems: apps that took forever to load, databases that didn’t have the food you were actually eating, and interfaces that made logging a meal feel like filling out tax forms.

So we made something different. Kilo focuses on the stuff that actually matters when you’re trying to understand your nutrition. It’s built for real life, not for people who have time to weigh every grain of rice.

Why Kilo works where others don’t

We’ve been down the rabbit hole of overcomplicated nutrition apps. Here’s what we learned:

Speed matters more than you think. When logging food takes 30 seconds instead of 5, you just stop doing it. That’s why we built Kilo natively for Apple devices—no web wrapper, no lag time. You can log an apple in 3 taps, find “chicken breast” instantly, and move on with your day.

Your phone isn’t always connected, but you still need to eat. Everything in Kilo works offline. Log your lunch on the subway, track dinner at that restaurant with terrible WiFi. It all syncs up when you’re back online.

Most apps dump too much information on you at once. Charts, graphs, percentages, streaks—it’s exhausting. We show you what you need to know when you actually need to know it. Your daily overview is simple: calories, protein, carbs, fat, and a couple other things that matter. That’s it.

What you actually get

Food logging that doesn’t suck. We use the USDA’s database of 350,000+ foods, so chances are we already have whatever you’re eating. Recent foods and favorites are right up top, and if you’re eating packaged stuff, just scan the barcode.

Can’t find something? Add it yourself. We handle the annoying conversion stuff—cups to grams, ounces to whatever, even “about a handful” if that’s how you think about portions.

A daily view that makes sense. Calories, protein, carbs, fat, and the basics. Simple progress rings show you where you stand. No confusing pie charts or overwhelming data dumps that make you feel like you need a nutrition degree.

Weekly and monthly trends if you want to dig deeper. See when you tend to eat more, what nutrients you’re consistently low on, stuff like that. But only if you want to—the app doesn’t nag you about it.

Goals that actually work for your life. Tell us what you’re trying to do and we’ll suggest realistic targets. As you track your food and weight, everything adjusts to keep you on the right path without being ridiculous about it.

Weight tracking that’s not weird about it. Log your weight when you feel like it, see your progress over time. Works with pounds, kilograms, or stones depending on what makes sense to you.

Wherever you are

Your iPhone is probably where you’ll do most of your logging—grabbing lunch, at the grocery store, wherever. The iPad version is great if you’re planning meals or just prefer a bigger screen. Home screen widgets let you log food without opening the app, which is surprisingly useful.

The Mac app gives you the full experience when you’re at your computer. Some people like to do their meal planning there, or just log food when they’re already at their desk working.

Oh, and if you have an Apple Vision Pro, Kilo works there too. We’re not sure why you’d want to log food in mixed reality, but hey, the future is weird.

Technical details

We built Kilo with SwiftUI and SwiftData because we wanted it to feel like it belongs on your Apple devices—fast, reliable, and consistent with everything else you use.

Your data is yours. We encrypt everything, we don’t sell your information, and you can export or delete your data whenever you want. The app works completely offline when you need it to, then syncs everything when you’re connected again.

Getting started

You need iOS 17 or newer (macOS 14 for Mac, visionOS 1 for Vision Pro). The app takes about 50MB to start.

Download it, tell us your basic info and what you’re trying to accomplish, log something you ate, and check your daily summary. That’s pretty much it.

One thing we’ve learned: consistency beats perfection. Log what you can, even if you’re not sure about portions or you’re missing ingredients. Better to have imperfect data than no data. Use the recent foods list—it gets smarter the more you use it. And glance at your daily summary in the evening; it helps you notice patterns without being obsessive about it.

Questions people ask

How much does it cost? Basic food logging is free. Premium stuff like detailed analytics and advanced goal setting costs money, but there’s a free trial so you can see if it’s worth it.

What if I don’t have internet? Everything works offline. The food database, logging, progress tracking—all of it. When you get back online, everything syncs up.

How accurate is the food data? We use the USDA database, which is pretty comprehensive and gets updated regularly. For packaged foods, we pull data from barcodes when we can. It’s not perfect, but it’s good enough to be useful.

Can I import my data from another app? Yeah, we support most of the major nutrition apps. Check the help docs for details on how to do it.

Is my data safe? Your health information is encrypted and stays private. We don’t sell it or share it with anyone. It’s your data—you can export it or delete it whenever you want.
