MuscleFlip is a fitness tracking app developed for all gym-goers, lifters, and dieters to dramatically visualize their bodily evolution.

Custom "Comparison Images" with Millimeter-Perfect Adjustments It does more than just place past and present photos side by side. You can intuitively resize (pinch-in/out) and move (drag) photos to freely adjust the layout, ratio, and positioning. Even if the camera angles or distances differ, you can align them perfectly to accurately compare and analyze muscle growth or waist trimming. 2. "Time-Lapse Video Generation" to Connect Your Evolutionary Journey Convert your accumulated daily progress photos into a single timeline video (flipbook-style video) with just one tap. You can always look back at the motivating process of your body leaning out and your muscles growing bigger in one smooth video. ◆ 3 Features You’ll Love No Login Required, Start Instantly: Start capturing and tracking your progress the moment you open the app. 100% Private & Secure: Your data is securely stored locally on your device.
