AI Meal Tracker is a private food diary that turns meal photos into nutrition estimates — calories, protein, carbs, fat, fiber, sugar, and sodium — so you can hit your daily goals without spreadsheets or sign-ups. Snap or pick a photo and AI estimates what's on your plate, search foods or scan barcodes powered by Open Food Facts, edit any value, or log manually anytime. Your daily diary includes a day-by-day meal log with a calorie goal ring, macro breakdown, Quick Add for favorites and recent meals, and optional logging reminders. Track trends with today's macro donut chart, a water intake tracker with daily goal, weekly calorie trends and streaks, and a weight log with smooth charts (1W / 1M / 3M / All), optional target weight line, and optional Apple Health sync. Private by design: no account, no cloud, no sign-up — meals, water, and weight stay on your iPhone. Photo analysis uses your own OpenAI API key (stored in the iOS Keychain); food search, barcode scanning, and manual logging work without a key. Set calorie, protein, and water goals with a built-in calculator, choose kilograms or pounds, and see calories left and latest weight on a home screen widget. AI estimates are for general wellness tracking only — not medical advice.
4D Rubik's Cube Explorer is an interactive application that brings the classic Rubik's Cube into the fourth dimension. Instead of solving a standard 3×3×3 cube, users can explore and manipulate a 3×3×3×3 hypercube puzzle, where each visible structure represents a projection of a higher-dimensional object. The app is designed to make 4D geometry more intuitive through play. Users can rotate, inspect, and interact with the puzzle while learning how pieces, stickers, cells, and moves behave in a four-dimensional space. By translating abstract mathematical concepts into a hands-on visual experience, the application helps users understand spatial relationships that are normally difficult to imagine. Beyond being a puzzle, the app functions as an educational tool for exploring higher-dimensional thinking, computational geometry, and game-based learning. It invites players, students, researchers, and puzzle enthusiasts to ask a simple but fascinating question: what would a Rubik's Cube look like in the fourth dimension?
