Your tennis journal that remembers patterns, opponents, and gear. A tennis journal for players who care about the story of their game, not a wall of charts. Log a match, a practice, or a hit while it’s still fresh, then let an optional coach that remembers read what you wrote. Between games, there’s a quiet moment, a changeover, when you actually think about what just happened. Changeover is that moment, kept. LOG EVERY MATCH • The score, how it felt, what clicked, what to try next time. Log it while it’s still fresh, or put this weekend’s match on the schedule first. • Type an opponent you’ve played before and the last thing you wrote about them comes right back. • Watch your streak, your competition record, and the themes that keep showing up in your own words. YOUR AI COACH • Changeover AI reads your journal, not the internet: strengths, recurring patterns, practice ideas, and match reflection drawn from what you logged. • Ask Changeover a question about your game and get an answer from your own history. • Free for 2 weeks, then $14.99/year. Optional. Everything else in Changeover is free. EQUIPMENT TRACKING • Keep your rackets, shoes, and strings in the bag, setups and tensions included. • See how many hours are on that string bed and which racket you’ve been playing. • Restring with one tap and the journal remembers the date. SHARE YOUR WINS • Turn a good session or a good month into a clean card. • Or a transparent sticker to drop over a photo in your story. PRIVATE BY DESIGN • Your journal lives on your phone. No account. No feed. • Reminders are opt-in and stay on your device. • Changeover AI only reads a snapshot of your notes when you ask, with names removed. Remember what happened. Learn from it. Play better next time. Terms of Use: https://trevornogues.github.io/changeover-public-pages/terms/ Privacy Policy: https://trevornogues.github.io/changeover-public-pages/privacy/

A smoother first session, and cleaner share cards. Get started in minutes: Tell us how you play, log a recent match, practice, or hit, add what’s in your bag, and optionally turn on reminders. Skip anything you don’t need. After you save: A quick next step: share a win, schedule the next match, add a note, or turn on reminders. Gentle guidance: In your first two weeks, Home suggests one useful next step at a time. Share cards: Six simple looks (horizontal or vertical; clear, court green, or cream), with less empty space so your result stays the focus. Keep logging! Changeover gets more useful the more you write down.
