Changeover
Your tennis, remembered.
The match journal for competitive players. Log every match, practice, and hit, spot the patterns that keep costing you sets, and walk on court against a repeat opponent with a plan.
Free on iPhone · New in September 2026 · See pricing for Changeover AI
Changeover is a calm, local-first tennis journal for matches, practices, and casual hits, with an optional AI companion that reads a sanitized snapshot of your history when you ask it to.
Your journal lives on your phone. No account. No feed. Reminders are opt-in and stay on your device.
Built for league, tournament, and club players who want to remember their matches. It is not a live scoring app, not a stats dashboard, and there is no social feed.
What Changeover does
Log the match, remember the pattern.
Score, how it felt, what worked, what didn't, and what to remember for next time. About a minute, while it's still fresh.
Spot the patterns that keep costing you sets.
“You've mentioned your serve in 8 of your last 10 match notes.” Patterns are counted on your phone from your own notes and ratings. Free, no network.
Every racket, string, and tension, with hours on the string bed.
Keep your rackets, shoes, and strings in the bag, setups and tensions included, so the journal remembers what you were using and how many hours are on that string bed.
Ask Changeover about your own game.
“Why do I keep losing close matches?” Insights, practice ideas, and match reflection drawn from what you logged, not generic tips from the internet. Part of the optional Changeover AI subscription.
Also in the free journal
- Last time vs. Type an opponent you've played before and the last thing you wrote about them comes right back.
- Streak and competition record. Your weekly streak, your record by league, tournament, or casual, best surface, tiebreaks, and deciding sets.
- Matches, practices, and hits. Set-by-set scores, multi-area practices, quick casual hits, and this weekend's match on the schedule.
- Share cards. Turn a good session or a good month into a clean card, or a transparent sticker to drop over a photo in your story.
- Reminders, opt-in. Scheduled on your phone, never sent from a server. Off by default.

Questions players ask
What does Changeover AI see?
A sanitized snapshot of your history, and only when you ask. Before anything leaves your phone, opponent and partner names are replaced with aliases like “Player A”, in the fields and inside your notes. The snapshot goes to our server and then to OpenAI to write the answer; we set store: false and do not keep a copy of your journal or the answer on our servers. Everything else (Trends, Patterns, streak, Last time vs.) runs on your phone with no network. The full detail is in the Privacy Policy.
Do I need an account?
No. There is no sign-up, email, or social login. Purchases go through your Apple ID, and Restore Purchases brings Changeover AI back on a new phone.
Is the journal free?
Yes. Full journaling is free with no limits: matches, practices, hits, notes, ratings, history, patterns, streak, equipment, and share cards. Changeover AI is the only paid part, and it's optional.
How do I cancel Changeover AI?
Any time, from your App Store subscription settings: Settings → Apple ID → Subscriptions → Changeover. If you cancel during the free trial you're not charged. The journal keeps working either way.
Why I built this
I'm Trevor Nogues. I built Changeover because I kept walking off court knowing exactly what had gone wrong (second serve getting attacked, going passive with a lead) and a few days later the details were gone. Notes-app entries never added up to anything. A changeover is the sit-down between games, the moment you actually think about what just happened. I wanted an app that kept that moment: quick to log, calm to read back, and useful the next time the same opponent turns up.
Changeover is a solo project. Your journal stays on your phone, there's no account, and the AI is optional. If something is off, email changeoverjournal@gmail.com or open an issue on GitHub.
