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.










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!

@klaudia_rzeszot Totally fair question — and thank you! Really happy the design/onboarding is landing.
You don’t have to track everything perfectly. One photo per meal is usually enough to get you in the right ballpark, and that’s the whole goal: know if you’re roughly under/over your daily target without it becoming a second job.
A good “low-friction” approach:
- Snap your main meals (breakfast/lunch/dinner)
- Don’t stress about tiny things unless they’re big calories (oils, sauces, alcohol, snacks)
- If something looks off, just tell gram what’s missing or adjust the portion it assumed
Cheat weekends: up to you 😄 If you want the least effort, track the big meals and call it a win. If your goal is fat loss and weekends tend to be where things go off-track, even a rough log on those days can be super eye-opening.
The key is consistency, not perfection.
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?

@yellow_yetti Thank you! 🙏
No blog or articles — it's purely a tracking tool. Intentionally kept it focused.
Most calorie apps try to do everything: recipes, articles, meal plans, social features... and end up cluttered and overwhelming. I wanted 0xCal to do one thing really well: make logging fast and painless.
For actual nutrition advice, I'd rather people follow experts they trust than read generic blog content inside an app.
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

@grey_seymour Haha no web3 here — just calories! 😂
The "0x" came from my dev background. Felt techy and minimal, and "0xCal" just looked clean. Plus most good names are taken so you gotta get creative 🤷♂️
No Android plans right now — I'm a solo iOS dev and SwiftUI is my happy place. But if enough people ask (tell your fiancée to comment here 😄), maybe someday! For now it's iOS only while I make sure that experience is solid.
And thank you! The design love means a lot — that was the whole mission. Appreciate the kind words and the PH support! 🙏

@raven_lui You nailed it — simple interface = actually using it daily. That was the whole mission.
Voice input: Not yet, but it's a solid idea. Right now you can type naturally ("oatmeal with banana") or snap a photo. Voice would be a nice addition for hands-free logging.
Feedback: Yes! The app shows visual feedback — green cards when you're on track with your goals, red when you're over. Plus it factors in your workouts and steps from Apple Health, so you see the full picture at a glance. Not overwhelming advice, just a quick "am I doing okay today?" signal.
Keeping it simple but useful. Thanks for checking it out! 🙏
minimalist phone: creating folders
AI scanner is top here. Definitely a feature that differentiates/positions your tool ;)

@busmark_w_nika Thank you! I spent a lot of time on that. It works with actual food plates AND nutrition labels – the labels give the most accurate results since it reads the exact values. Really happy with how it turned out!
minimalist phone: creating folders
@namedix Can the user customise the amount on his plate? (in terms of grams etc.)
0xCal
@busmark_w_nika Yep! When gram analyzes your food, it always shows the portion size it assumed (like "~150g").
If it's off, you just tell it in the chat: "actually it was about 200g" or "smaller portion, maybe 100g" — and it recalculates instantly.

@namedix This is neat. Such tools are smarter than I thought initially. :D

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?
0xCal
@alex_gerasimenko Great question! I actually kept it pretty minimal — mostly just numbers.
For daily tracking (calories, macros), I show the raw numbers like "88/120". Gives you exactly what you need to make decisions: "can I fit this snack?" — no guessing.
The goal number (the "120" part) comes from your personal data — during onboarding we pull height, weight, age from Apple Health and ask about your activity level and goals. Then calculate your actual TDEE and target based on whether you want to lose, maintain, or gain.
For the weekly/monthly success view, I use colored rectangles for each day — green if you hit your goal, different shade if you didn't. It's more of a calendar heatmap than a progress bar.

Thanks for the response! And one question, do you use AI to reply to messages here on PH? I mean your reply has some dashes and the punctuation is perfect ;)
0xCal
@alex_gerasimenko Haha busted! I use AI to proofread and clean up my English - not my first language so it helps with grammar and punctuation. But the actual thoughts and answers are all me :)
Padel Chess
@namedixI definitely can relate to this, thanks for the transparency :)
@namedixI see you with the 0x ser, what do you have planned next?
"..apps that felt like punishment.." - feels like all tech now. I appreciate your attention to detail here for the user. Let's chat when you're free.

@0x0x Next up: goal editing, weekly summaries, and Apple Watch app on the horizon. Keeping it lean and focused.
