Point your phone at a plate and get calories and macros back in seconds. No weighing, no scrolling a database, no guessing what was in it. SCAN IT, DO NOT HUNT FOR IT Photograph a meal and Titan reads it back to you. Scan a barcode and we read the label. Search hundreds of thousands of foods when you would rather just type. If a scan fails we say so, because an invented number is worse than no number. AUSTRALIAN MENUS, BUILT IN Eating out is where most trackers give up. Titan carries Australian chain menus with per-item portions taken from official nutrition guides, so a six-pack of nuggets and a twenty-pack are two different entries, because they are two different meals. TRAINING THAT ANSWERS TO YOUR RECOVERY Log sets, reps, weight and rest with a tracker that keeps up mid-session. Tell Titan how you slept, or connect Apple Health and let your watch tell it, and the next session is built for the body you actually turned up with. Progression is planned in blocks, not guessed week to week. YOUR NUMBERS, MEASURED Connect Apple Health and Titan reads sleep, resting heart rate, HRV and steps. Daily totals only, never your raw records, never sent to an AI provider. See them with thirty days of history behind them, and see what today's walking was worth in calories. Readiness stops being something you estimate and starts being something you measure. REAL COACHES, NOT JUST ALGORITHMS Browse coaches from Titan Fitness Coogee, request the one you want, and message them inside the app. You choose exactly what you share: your workouts, your macros, your stats, or none of it. Every coach is approved before they appear. BUILT FOR RACE DAY Racing HYROX? Set your race date and division and Titan builds a periodized prep block that counts down to it, with an honest projected finish range that moves as your training does. WHAT YOU GET - Food logging by photo, barcode or search - Australian supermarket and fast-food data, not a US-only database - Workout logging with rest timers, an exercise library and a calendar - Daily calorie and macro targets from your own body stats and goals - Apple Health sleep, resting heart rate, HRV and steps, with history - Meal plans that respect your allergies, diet style and the food you like - Weekly progress you can read in one glance HONEST BY DESIGN Every number that prescribes something has its source inside the app, on a Health sources screen: the equations, the studies, the guidelines, each with a link. If we cannot cite it, we do not claim it. And when a scan fails, you get an error, not a plausible-looking guess. YOUR DATA Your workouts, meals and messages are yours, isolated per user at the database level. Delete your account and everything goes with it, from inside the app, in two taps. We do not sell your data. Titan Fitness is free to use.
