Most calorie apps feel like a chore – cluttered interfaces, endless database searches, designs stuck in 2015. 0xCal is different. Built for people who care about the apps they use. Describe what you ate naturally, or snap a photo. AI handles the rest. Dark mode first. Minimal UI. Native iOS feel. No ads, no clutter – just a beautiful tool that helps you reach your goals without compromising your home screen. The calorie tracker that finally belongs on your phone.
Hey Product Hunt!
I built 0xCal because I was tired of calorie apps that felt like punishment.
Every app I tried had the same problems: cluttered UI, overwhelming features, and designs that looked like they hadn't been updated in a decade. They worked, but I dreaded opening them.
I wanted something I'd actually enjoy using. Something minimal that respected my attention. The kind of app that earns a spot on a curated home screen.
So I built it myself:
→ Describe your food naturally – AI figures out the nutrition
→ Or snap a photo of your meal or a nutrition label
→ Clean dashboard showing just what matters
→ Dark mode first, native iOS feel
I spent as much time on the design as the functionality. Every screen, every animation, every detail was intentional.
If you've ever abandoned a calorie tracker because it felt like homework, I'd love for you to try 0xCal.
Happy to answer any questions about the design process, tech stack (SwiftUI, HealthKit), or anything else!
I've been using it for a few days now, and it’s already saving me a ton of time.
Was stoked to see the "0x", thinking there was some web3 integration 😂 alas, none in sight. What compelled you to go with 0xcal as the name? Really cool app btw, it's clear you put lots of love into the design. Any plans for an Android version? (I'm all iOS all the time, but my fiancée - who would love this - is a Pixel-enjoyer... for now...!)
PS - congrats on the launch/a remarkably successful PH campaign! :D
When you say “describe what you ate naturally” or “snap a photo and AI handles the rest,” what’s your approach to the hardest part—portion size and invisible ingredients—and how do you balance speed with giving users enough control to correct the model without turning it back into a chore?
wow, that looks nice! wish you continuing succes with 0xCal! was curious, does your app have any 'blog' with articles or recommendations for different types of health goals, or is it simply a tool for calorie tracking only?
Great UI indeed. Just curious, how did you decide if to put a numbered progress e.g. 88 /120 or to put a visual one e.g. radial progress bar?
Congrats on the launch🚀 This is a great idea. An amazing feature would be also to enable users to upload images of their food to be analyzed by AI. The accuracy might be fluctuating in the beginning but with the correct ML and feedback loops would be enhanced over time
The app looks really cool. Just signed up for the trial.
I actually also signed up for MyFitnessPal a few days ago, but think I might cancel that because I just need the calorie tracking.
Your app seems to do this well and has all the necessary Apple Health integration, plus AI chat, plus photo meal capture.
Well done, I think this will be a keeper!
Is it enough to just add one picture of each meal I have? Do I have to keep track of everything I eat every day (cheat weekends too? 🙂). I usually see most calorie-tracking apps as a chore, but this one seems very promising. And I love the design and onboarding so far!
I track meals regularly for fitness, and 0xCal immediately caught my attetion — I downloaded it right away to try it out. The UI and typography are genuinely fun, and it feels refreshingly minimal compared to most calorie apps.
Quick question: AI photo recognition in most apps isn’t very accurate(especially for mixed or homemade meals). Curious how 0xCal improves accuracy and makes corrections easy.
The "apps as punishment" analogy resonates! Clean UI matters when you're using something daily. How does 0xCal handle restaurant meals where you don't have exact nutrition info? Does the AI learn your preferences over time?
A beautifully designed app. I was a beta tester for this project and can confidently say the author went the extra mile. The attention to detail really shows. Counting calories works flawlessly.
Great launch!
AI scanner is top here. Definitely a feature that differentiates/positions your tool ;)
