## What is FORMULA?

FORMULA is a tennis improvement journal that helps recreational players turn lessons from practice and matches into clear actions for the next session.

You do not need to write a long diary. Keep practice reviews, shot tips, strengths, opponent plans, and point construction together as your own personal tennis playbook.

REVIEW PRACTICE AND MATCHES WITH PDCA
Record your plan, what happened, what worked, what needs improvement, and the next action. Browse previous entries on a calendar and see your monthly and all-time activity totals.

BUILD A USEFUL SHOT NOTEBOOK
Organize forehand, backhand, serve, volley, and smash notes. Add detailed shot types, save multiple tips for each type, and rate them from 1 to 10. FORMULA calculates shot averages and displays your strengths on a status chart.

MAP POINT PATTERNS ON A TENNIS COURT
Tap the start and landing point of each shot to create a clean visual route. Record whether you or your opponent hit the ball, choose the shot type, add a note, and review the complete rally in order.

PREPARE FOR DIFFERENT OPPONENT TYPES
Create plans for opponent styles such as aggressive hitters or consistent defenders. Keep separate lists of what worked and what to avoid.

KEEP YOUR NEXT FOCUS VISIBLE
Place a personal motto, your next practice theme, favorite point patterns, favorite shots, and today's record on the home screen.

DESIGNED FOR QUICK, PRIVATE USE
• No account required
• Data stored on your device
• Works offline
• Available in Japanese, English, and Spanish

The free plan includes up to 3 favorite point patterns, 10 detailed shot types, 1 motto, and 2 opponent-type plans. Premium removes these limits.

Capture the small lesson after every session and build a game you can reproduce under pressure.
