It visualizes and assists your analysis with powerful features like auto-replay triggered by dart impact sounds, AI skeleton tracking, and customizable grid lines. It fully supports both soft tip and steel tip darts.

[Key Features]

Auto-Replay via Impact Sound (Delay Cam)
The app detects the sound of the dart hitting the board and automatically replays the video of your previous throw. You can immediately check your form right after throwing.

Burst Shots (Pro feature)
Automatically captures your form for all 3 throws by detecting impact sounds. Swipe the screen for smooth frame-by-frame playback to analyze the depth of your takeback and the exact moment of release in detail. You can also overlap the 3 throws with transparency to visualize the differences between each shot.

AI Skeleton Tracking (Pro feature)
AI automatically detects your skeleton and draws tracking lines. It visually traces your arm movement and body sway, helping you check your swing path and build your ideal form.

Versatile Analysis Tools (Pro feature)
Packed with a suite of useful tools to spot inconsistencies in your form:
• FLEX: Customizable grid lines where you can freely adjust the number of divisions and their positions.
• LINE: Freehand lines you can draw anywhere on the screen.
• MARKER: Visual markers you can place on specific points you want to focus on, like your elbow or setup position.
• MEDIA: Overlay reference images or videos with transparency to compare them directly with your own throw.

Gallery
Save your recorded videos and burst photos within the app. By comparing your current form with a past form from when you were playing well—either side-by-side or overlapped—you can see exactly what has changed at a glance. You can also add notes to each shot.

[Free vs. Pro Version]
This app is essentially free to use. The Free version includes the core "Delay Cam" (auto delay replay) and basic analysis using fixed grids (3x3 / 5x5).

For players who want more advanced analysis, we offer a "Pro Version" via in-app purchase. The Pro version is a one-time purchase, not a subscription! Once you upgrade, you get unlimited access to all premium analysis tools, including Burst Shots, AI Skeleton Tracking, all versatile analysis tools, and the Gallery features.
