Our Mission
0xCal exists to make calorie tracking effortless and genuinely pleasant. We believe staying mindful of what you eat should not feel like homework. By combining AI-powered photo and chat logging with a clean, native iPhone experience, we help people stay accountable to their health goals without the friction of searching databases or scanning barcodes.
What We Build
0xCal is a design-first calorie tracking and nutrition app for iOS. Snap a photo of your meal or describe it in natural language, and 0xCal logs the calories and macros in seconds. It integrates with Apple Health, supports goal-based programs, and is built entirely with modern, native Apple technologies.
- AI photo logging — take a picture of your plate and get instant nutrition estimates
- Chat to log — describe what you ate and let the AI parse it for you
- Apple Health integration — sync weight, activity, and nutrition data
- Personalized programs — calculated calorie budgets to lose, maintain, or gain weight
Who We Are
0xCal is an independent app studio founded and operated by Bartłomiej Pichalski. We are a small, focused team dedicated to crafting high-quality, thoughtfully designed software for the Apple ecosystem.
Bartłomiej is an iOS developer and designer who builds 0xCal end to end — from the SwiftUI interface to the backend infrastructure. After finding existing calorie trackers slow, cluttered, and unpleasant to use, he set out to build a tracker that is fast, beautiful, and AI-native from day one.
Our Values
- Design first — software should be a pleasure to use, not a chore
- Privacy by default — we collect as little as possible and are transparent about it
- Honest AI — estimates are clearly presented as estimates, with easy ways to correct them
- Built natively — we embrace the latest Apple platforms to deliver a fast, reliable experience
