Getting started
Create an account with email or Google. You'll land on the Dashboard — empty for now. Tap “+ New match” to log your first one.
The Dashboard
Six summaries at the top: Win rate, Sets, Games, Hold rate, Breaks won and Current form. Each reflects your current filter (year, format, kind). Below: your win-rate trend and recent matches.
Adding a match
On New Match, start by recording the opponent, court and score so the result is not lost. Then use Score Timeline, Opponent, Context, Performance Review and Smartwatch to add the level of detail you actually remember. You can save the core match first and return later to enrich the same record.
Matches list
Search by opponent, filter by format and kind, and click any row to edit. Bulk actions and CSV export are in Settings.
Stats
Deep cuts of your data: head-to-head, by court, by surface, by temperature, by year/month, by opponent age & experience, by ball state, even by rainy weather or floodlights.
AI Insights
Click “Ask AI” to get a coach-style narrative based on your match history. AI analysis is available once you have logged match data and generally becomes more informative as your match history grows. When you request AI Insights, only privacy-filtered, allowlisted match data is sent; personal identifiers are removed or pseudonymized in line with the Privacy Policy.
Smartwatch import
On the Add Match page, scroll to “Smartwatch data”, upload a screenshot from your watch app and we'll auto-fill kcal, duration, avg/max BPM and HR zones using AI.
Export & delete
From Settings you can change your password, manage cookies, export everything to CSV, or permanently delete your account.
Troubleshooting
I can't sign in
Make sure you're using the same provider you signed up with (email or Google). If you forgot your password, use the password reset link on the sign-in screen. Still stuck? Use the Contact link in the footer with the email you used.
My match didn't save
To save a match, an opponent and court are required. Scores and additional details can be added progressively. If you see a red error toast, the form identifies the missing field. Network issues can also block saves — try again on a stable connection.
AI insights aren't generating
AI insights need at least a handful of logged matches to find patterns. If you have enough data but still see an error, the AI service might be temporarily rate-limited — wait a minute and try again.
Smartwatch screenshot isn't being parsed
The parser works best with clear, high-contrast screenshots from Apple Watch, Garmin, Polar or Fitbit. Crop tightly around the workout summary and make sure heart-rate and duration text is readable.
Stats numbers look wrong
Most stat surprises come from missing serve order in game-by-game matches — without it, the app can't compute holds and breaks. Edit the match and double-check who served first in each set.
Who is Tennis Log for?
Tennis Log is built for any player who wants to take their tennis a little more seriously than just remembering the score on the way home. It works equally well whether you've been playing for three months or three decades — the depth of the tool scales with the depth of your match log.
Beginners
If you've just started playing, the most useful thing Tennis Log gives you is a simple, structured record of your first matches. You don't need to track holds and breaks yet. Just log opponent, score, surface, and a one-line note. As your history grows, you can compare later matches with earlier ones while taking opponent strength, format and other context into account.
Intermediate players
For club and league players, Tennis Log shines. Game-by-game tracking gives you real hold and break percentages. AI analysis is available once you have logged match data and generally becomes more informative as your match history grows. Surface and opponent filters can help you investigate differences, and a structured match log can give you clearer questions to take into practice or a coaching session.
Competitive players
If you compete in tournaments or a serious league, Tennis Log functions as a personal performance database. Track conditions, opponent handedness, ratings for both sides, smartwatch data, mental notes — and slice the resulting stats by year, surface, kind (friendly vs official), partner and more. Export to CSV anytime and bring the data into a coaching session.
