SlyMask baseball

Record a pitch or swing, get private on-device analysis, follow a personalized 7-day plan, then reassess on Day 7 and see what changed.

Record it. Understand it. Train for change.

SlyMask is a baseball training and analysis tool for players, parents, coaches, and enthusiasts. No extra hardware is required. Record or import a pitching or batting video on iPhone, receive on-device motion analysis, and turn the result into a practical training plan.

From one analysis to measurable progress

1. Import a pitching or batting video.
2. Review key motion phases, angles, confidence, and training guidance.
3. Create a personalized 7-day plan from that result.
4. Complete short daily drills and reassess on Day 7.
5. Compare reliable before/after metrics and create a progress report.

Review key pitching phases and motion changes, including rhythm, posture, movement sequencing, and release timing.

• AI Swing Analysis
See swing path, key body movement, contact timing, and overall trends in a more understandable visual report.

• Personalized 7-Day Training
Turn analysis into short daily drills focused on the areas identified in your video. The included Day 7 reassessment does not consume a free AI credit.
