Tennis Day: AI Tennis Coach

Tennis Day puts an AI tennis coach, a visual season calendar, and your own court diary in one calm app.

AI COACH — BUILT AROUND ONE USEFUL MOMENT

Choose a serve, rally, forehand, backhand, or volley from your library, then trim only the moment you want reviewed. AI Coach turns the selected clip into technique findings, timestamps, and a practical day-by-day plan with timed drill blocks, coaching cues, progress checks, and one mindset note.

• One lifetime video-analysis try: up to 15 seconds • Coach Pro clips: up to 60 seconds • Feedback shaped by your level, focus, and weekly practice schedule • Save successful reports to My Training Plans and reopen them from Coach Home • Short, focused clips produce the most useful feedback

You can also ask the text coach about technique, a seven-day training plan, match mindset, or a post-match review.

YOUR TENNIS SEASON, EVERY DAY

Follow the 2026–2027 season through an original illustrated poster and a line for every day. Keep Wimbledon, the US Open, the Australian Open, Roland-Garros, and other key dates close without turning your Home Screen into a scoreboard.

• Daily Poster, Daily Quote, Month Grid, and Lock Screen widgets • Double-tap to log the days you play • Played days become poster stickers in the month grid • Monthly recap cards to save or share • English, Simplified Chinese, Traditional Chinese, and Japanese

PRIVACY BY DESIGN

Only the clip you select is uploaded. A private processing service creates up to eight reduced still frames for AI analysis. The uploaded clip and temporary frames are normally deleted promptly after processing, with a one-day storage lifecycle as a cleanup fallback. Text prompts are not stored in our first-party database. See the Privacy Policy for full details.

PURCHASES

Tennis Day is free to download.

Eligible users receive one lifetime 15-second video analysis, used only after a successful result. Coach Pro is an auto-renewable weekly subscription that includes unlimited text coaching plus 10 successful video analyses per subscription week, up to 60 seconds each. The current U.S. reference price is US$13.99 per week; your App Store purchase sheet shows the price and currency for your storefront.

After all 10 included analyses in an active subscription week succeed, an eligible subscriber may buy one additional analysis at a time. The current U.S. reference price is US$1.99; your storefront price controls. Valid unused extra-analysis credits do not expire unless the purchase is refunded or revoked.

Existing calendar packs remain separate one-time purchases. Coach Pro does not replace them, and existing calendar purchases remain available.

Payment is charged to your Apple Account. Coach Pro renews automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in your Apple Account settings. Refund decisions are handled by Apple.

AI coaching can be inaccurate and is general educational information, not medical advice or a substitute for an in-person qualified coach or clinician.
