About this app

Let your spinning battle top leave dazzling trails! Beytail uses AI to instantly identify the position of the top in the frame and automatically overlay dynamic trail effects—fire, lightning, stardust, waves, frost… every battle feels like a special attack.

More than just real-time filters, you can also add effects directly to existing battle videos from your phone's photo album for post-production output, transforming old videos.

✨ Key Features

━━━━━━━━━━━━━━

🎯 AI Real-Time Recognition Automatically detects spinning tops when the camera is on, and the trail follows its movement without manual selection.

🎨 Multiple Cool Effects Built-in free effects such as lightning, fire, and stardust, with advanced effects like towering waves, exploding blades, raging ice rifts, and money impact available to unlock. The trail color automatically uses your top's color, making it unique. 🎬 Shoot and Record Simultaneously
Instantly preview effects and record video directly; the finished product is automatically saved to your album.

📂 Post-Production of Album Videos
Select an existing video, apply effects, and re-export—both portrait and landscape formats are supported.

⚡ Smoothness and Power Saving Balance
Switch between 60fps mode for ultimate smoothness or a standard mode to maintain power saving and lower heat generation.

🔒 Privacy and Security
All recognition and effects are processed entirely on your device; your camera feed and videos are never uploaded.
