Quasar

Most calorie apps count. Quasar thinks.

Quasar is an adaptive metabolic engine for people serious about body composition. While other apps give you a static target, Quasar recalculates your BMR, TDEE, and macro splits on every weight log. Your plan evolves as your body does.

🔥 𝗙𝗢𝗨𝗥 𝗦𝗣𝗘𝗖𝗜𝗔𝗟𝗜𝗭𝗘𝗗 𝗧𝗥𝗔𝗜𝗡𝗜𝗡𝗚 𝗠𝗢𝗗𝗘𝗦

𝗧𝗵𝗲𝗿𝗺𝗶𝗰 𝗘𝗻𝗴𝗶𝗻𝗲 Calculates the exact digestion cost of every meal — Protein (25%), Carbs (8%), Fat (2%) — and credits it back to your daily budget in real time. Built on peer-reviewed TEF research by Westerterp (2004) and Acheson et al.

𝗗𝗲𝗳𝗶𝗰𝗶𝘁 𝗖𝘆𝗰𝗹𝗶𝗻𝗴 Built on the MATADOR study (Byrne et al., 2017) — cycling deficit and maintenance prevents adaptive thermogenesis and produces greater fat loss than continuous restriction.

𝗟𝗼𝗮𝗱 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁 Pauses your deficit during high-stress periods, switches to maintenance, then resumes exactly where it left off.

𝗜𝗻𝗷𝘂𝗿𝘆 𝗥𝗲𝗰𝗼𝘃𝗲𝗿𝘆 50 conditions across 11 categories — fractures, sprains, surgeries, infections, chronic conditions, mental health, and more. Each with clinically-informed macro splits, BMR multipliers, and a personalized recovery message.

Includes a 𝗦𝘁𝗿𝗮𝘁𝗲𝗴𝗶𝗰 𝗖𝗵𝗲𝗮𝘁 𝗗𝗮𝘆: mark a cheat day, log the excess calories, and Quasar distributes precise daily reductions across your chosen recovery window — to the exact calorie. Next cheat day unlocks only after compensation is complete.
