Body Tracker - Progress Photos Stay motivated, stay consistent, and finally see the results of your hard work. Body Tracker - Progress Photos helps you capture, organize, and compare your transformation over time with a simple and private photo timeline. Whether your goal is weight loss, muscle gain, or body recomposition, seeing visual changes can be far more motivating than watching numbers on a scale. Built specifically for tracking progress pics, this app helps you create a complete visual record of your fitness journey from day one to your biggest milestones. See Your Transformation Clearly Progress often happens slowly. Daily changes are easy to miss, but when you compare progress pictures side by side, the difference becomes impossible to ignore. Body Tracker helps you organize progress photos into a clean timeline so you can easily review your body progress over weeks, months, and years. Whether you're documenting weight loss photos, tracking muscle progress, or monitoring a complete body transformation, everything stays organized and accessible. You can also track your weight alongside your photos — each weight entry is linked to your progress pictures, so the numbers and the visuals tell one story. Create consistent progress pictures from the front, side, and back to build a complete visual history of your fitness journey. Watching your body progress develop over time can provide the motivation needed to stay committed to your goals. Compare Before & After Results One of the most powerful features of Body Tracker is the ability to create and compare before and after photos with ease. View transformation photos side by side to identify subtle improvements in posture, muscle definition, fat loss, and overall physique changes. Compare before and after photos from any point in your timeline and instantly see the fitness results your hard work has created. Whether you're focused on weight loss photos, muscle progress, or body recomposition, accurate visual comparisons help you understand what is working and where you are improving. Designed for Fitness Goals Body Tracker is built for anyone pursuing: - Weight loss and weight loss photos tracking - Muscle gain and muscle progress monitoring - Body recomposition transformations - Weight tracking linked to progress photos - Long-term fitness journey documentation - Gym progress tracking - Personal body transformation goals Create Stunning Transformation Timelines Capture photos directly within the app or import existing images from your gallery. Auto-alignment uses advanced pose detection AI to completely eliminate alignment friction — it detects your pose and automatically crops and rotates each photo to match your previous shots, no ghost overlay, no manual lining up. Fine-tune with crop and rotate tools whenever you want. Export your progress pictures as a timelapse video and watch your body transformation unfold in seconds. Seeing months of gym progress condensed into a single video can be one of the most rewarding ways to celebrate your achievements. Private by Design Your privacy matters. All progress photos, before and after photos, and transformation photos remain on your device. We do not upload, store, or share your images. Your fitness journey stays completely private and under your control. Body Tracker requires a subscription to unlock full access. New users can start with a free trial; after the trial, the subscription renews automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel anytime in your App Store settings.
