Thelo - Body Scan–Powered AI Personal Trainer Thelo is an AI personal trainer built on proprietary body scan technology. Instead of generic workouts, Thelo uses a smart body scanner to analyze your body fat, muscle balance, structure, and recovery — then builds AI personal training plans that adapt as your body changes. This is training designed around your body, not averages. AI Personal Training Built From Your Body Scan Your body is unique. Your training should be too. Using a visual body scan, Thelo identifies: • Muscle imbalances and weak points • Genetic structure and proportions • Areas limiting growth or causing plateaus • Which muscles are recovered — and which aren’t Your AI personal trainer updates your workouts automatically based on this data. Smart Workouts That Adapt Daily Thelo’s AI personal training system adjusts your workouts based on: • Your schedule and available time • Gym or home equipment • Fitness level and training history • Recovery and recent workload No fixed plans. No wasted sessions. Just training that fits your life. Track Real Body Change, Not Just Weight Thelo’s body scanner helps you track what actually matters: • Daily body fat tracking • Body measurement changes over time • Muscle-specific recovery insights • Weight logging with full history • AI-guided progressive overload Your AI personal trainer shows you why progress is happening — or why it isn’t. See Progress With Clear Body Scan Insights Thelo turns your body scan data into clarity: • Visual body scan comparisons • Muscle-by-muscle progress breakdowns • Recovery vs workload balance • Objective feedback, not guesswork It’s AI personal training with transparency. Who Thelo Is For • Gym-goers tired of generic programs • People stuck despite training consistently • Anyone who wants data-driven progress • Lifters focused on physique, symmetry, and longevity Why Thelo Is Different Most fitness apps start with workouts. Thelo starts with a body scan. Powered by an intelligent body scanner and adaptive AI personal trainer, Thelo delivers AI personal training that evolves with you. Train smarter. Train for your body.

Verdict

The call

The clearest difference is in-app purchases: Studio Eres at none against Thelo's 12. Studio Eres also leads on rating (4.9 vs 4.6). Thelo's advantage is ratings volume (1.4K vs 45) and update cadence (every 10 days vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
