野球成長ノート

This app helps parents and children grow together, celebrating the "I did it!" moments of their baseball journey.

A baseball-specific growth record notebook for players, parents, and coaches of youth and amateur baseball teams.

Easily record daily practices and games, and visualize progress with graphs and an AI coach.

■ Visualize Growth with Records & Graphs
Automatically calculates batting average, on-base percentage, ERA, etc., and displays them in line and bar graphs.

Also records physical data such as height, weight, 50m sprint, throwing distance, and ball speed.

■ Gentle Advice from an AI Coach
Based on recorded performance and practice volume, the AI ​​coach praises strengths and suggests next goals.

Suggested goals can be set with a single tap, serving as daily practice markers.

■ AI Form Check (Video Form Diagnosis)

The AI ​​comments on pitching and batting forms from videos taken with your smartphone.

The advice is presented in the following order: "Good points → Areas of concern and areas for improvement → One-point practice you can start today," making it easy for children to understand. Recommended practice can be set as goals.

■ Measuring ball speed from video
Simply frame-by-frame the pitching video and align the release and catch moments to calculate ball speed.
You can record your progress with video and see your growth.

■ Habit formation with goals and badges
Check your goal progress with a bar. Consecutive records (streaks) and badges funnily encourage daily "persistence."

■ Team use (invitation only)
Create a closed team with your friends using an invitation code. Record games together and review team performance collectively. *Private and invitation-only for peace of mind.

■ Growth summary PDF
Create a PDF report summarizing performance and growth progress. Great for sharing with grandparents.

■ Secure device changes with account registration
With free account registration, your records are saved to the cloud. You can transfer your data even if you change devices.
(Guests without registration can start using it immediately.)
