Zazen Journal
How do I use the Action button on Apple Watch Ultra?
Open Settings on the watch, choose Action Button, and assign the Start Session shortcut from Zazen Journal. Each press then steps through Start → Pause → Resume. This is a one-time setup Apple requires; apps can't assign the button themselves.
Can I start and stop without touching the screen?
Yes. Double Tap (pinch your index finger and thumb twice, on supported watches) starts, pauses and resumes the timer — useful when your hands are busy.
Why is heart rate showing "Unavailable"?
The app needs permission to read heart rate from Health. On the iPhone, open the Health app, choose Sharing, then Apps and Services → Zazen Journal, and turn on heart rate. The timer works without it; you just won't see or record heart rate.
How do I record my weight?
After a session, tap the weight button on the summary screen, or open Settings → Sessions and choose the session. Turn the Digital Crown to set the value; the other unit is shown underneath. On iPhone, tap a session in the list. Flip the Pounds switch to change units — the value converts, it isn't reinterpreted.
I ended a session by mistake.
Right now, ending is final: the session is saved as it was when you pressed stop. Pausing first is the safer habit — the pause button is the large one on the right, and stop is on the left. Three improvements are planned: showing stop only while paused, resuming a session after it has been ended, and merging two sessions into one on the iPhone.

Three Numbers
What can I say?
Turn on Listen, then after each rally say one of these. The examples use the default team names, Blue and Orange; use whatever names your game has.
| Say | What happens |
|---|---|
| “point Blue” | Blue won the rally. Say who won the rally, not who scored: if the receiving team wins, no point is added and the serve moves to the second server or to the other team. |
| “undo” | Takes back the last change, including a reset. |
| “reset to Blue serving 2-3-1” | Sets the score outright. Say the numbers the way the score is called: serving team's score, the other team's score, then the server number. In singles, leave the server number off. Words work too, like “two three one” or “oh oh two”. |
| “rematch” | Another game with the same teams and rules. Only works once a game has been won, so saying it mid-game can't throw the score away. |
The same list, with your own team names filled in, is behind the ? button next to the Listen switch.
It scored the wrong team, or didn't score at all.
Say “undo” (or tap the undo button) and say it again. If the phone isn't sure which team you named, it deliberately scores nothing rather than guess. Three things help: wait for the phone to finish calling the score before your next command; say the team name exactly as it's set for the game; and pick names that sound different from each other. Short, similar names like “A” and “B” are easy to mishear. To change the words you say, give the teams those names when you start a new game.
Does it keep listening when the screen is locked?
Yes, and when you switch to another app. Turn Listen on before you lock the phone: iOS won't let an app start listening once it's in the background. Listening stops when you turn the switch off, or when something else takes over the audio, such as a phone call.
Does it need an internet connection?
No. Speech is recognized on the iPhone itself, so it works on courts with no signal, and no audio leaves the device. Voice commands are recognized in English (US).
It says on-device speech recognition isn't available.
Three Numbers only uses recognition that runs on the device, and some older devices and language setups don't offer it. Tap scoring, the spoken score and everything else still work. If it asks for permission instead, open Settings → Apps → Three Numbers and allow Microphone and Speech Recognition.
What happens to my music?
It keeps playing while the app listens. It dips while the score is called, then comes back.
How do I fix the score by hand?
Tap the undo button to step back one change at a time, or open Score → Edit Score… to set both scores, the serving team and the server number directly. Score also has a reset to the opening call, and Swap Sides to flip which panel is on which side when the teams change ends.
How does voice work on Apple Watch?
Hold the microphone button, say the command, and let go. Apple Watch can't recognize speech by itself, so the watch passes what you said to your iPhone, which works out the command and sends the new score back. That needs the iPhone in range with Three Numbers installed and Speech Recognition allowed. With the phone out of reach, pressing the button opens the watch's standard text input instead, where you can dictate or scribble the command. Tapping a team to score always works, phone or no phone.
The phone and the watch both call the score. Can I have just one?
They call it together on purpose, so whichever is nearer gets heard. When you score on the watch, the phone speaks too even if its Listen switch is off. To quiet one of them, turn its volume down.
Can I play singles, or to 15 or 21?
Yes. When you start a new game choose doubles or singles, play to 11, 15 or 21, win by 1 or 2, and who serves first. In singles the call is two numbers, with no server number.
Where are my past games?
In History on the iPhone, grouped by day. Swipe a game to delete it. Starting a new game before the last one was won keeps the unfinished game in History; a game where nothing was ever scored is dropped.

Practice Companion
How do I get a song into it?
Working a song out happens on your computer: install the app with the line on the Practice Companion page (a Mac with Apple silicon or a Windows PC). It opens in your browser; choose New Session from Audio File… for a song or a video on your computer, or Listen to a Tab… for what plays in a Chrome tab. The first song takes a few minutes; it's ready when the steps on the page are done.
Can I use it on an iPad or a phone?
Yes, to play and practise songs that have been worked out. On the computer, open Settings and move the sessions folder into Dropbox › Apps › Practice Companion. Then on the iPad or phone, open the site, choose Connect Dropbox, and your sessions are listed. Chord and lyric corrections you make there are saved back to Dropbox. You can also open a session exported as a zip file.
I added a song from my iPad, and it says it isn't analyzed yet.
A song added to Dropbox is worked out by the app on your computer while it's running. Once Dropbox has brought the result back, the song opens.
How do I share a song with a friend?
Choose Share… next to the session, or in the song's header, and send the link. Your friend can open it without Dropbox, read only, and with Dropbox choose Copy to my Dropbox to keep a copy of their own. Stop sharing takes the link back.
There's no sound.
A web page can only play sound after you've tapped or clicked on it: press Play once.
A chord or a word is wrong.
Tap the chord and choose Not this chord? to set the right one, or double-click a line of the lyrics to write it as it's sung. Corrections are kept with the session.
Where is my data stored?
In your browser, in your own Dropbox if you connect it, and on your own computer with the app installed. See the privacy policy.
Tuneshed
How do I tune just one string?
Tuneshed works out which string you're playing on its own. To tune only one, tap its button at the bottom of the tuner: it's outlined, and readings are measured against that string whatever you play. Tap it again to hear its note. Tap Auto to go back.
Why does the reading wait a moment after I pluck?
For about half a second after a string is plucked its pitch starts low and climbs before it settles. Tuneshed waits for it to settle, so you don't turn the peg the wrong way.
My low string reads a few cents different from another tuner.
A thick wound string's overtones run a little sharp of its fundamental, and tuners differ by a few cents on it depending on which part of the sound they follow. If it bothers you, widen In-Tune Range in the tuner's settings (the sliders button).
Quiet notes don't register, or it reacts to the room.
Open the tuner's settings and change Mic Sensitivity: High hears quieter notes and lets them ring longer, Low ignores more background noise. The bar under it turns green when what it hears is loud enough. It also helps to hold the phone or iPad close to the instrument.
How does the capo work?
On fretted instruments, tap Capo beside the tuning and choose the fret. Every string then tunes to the note it sounds with the capo on. The capo comes off when you choose another instrument. Keep Capo Position in the tuner's settings decides whether it stays on when you choose another tuning.
How do I make my own tuning?
Open the tuning menu above the meter and choose New Custom Tuning…. Give it a name and set each string's note. To change or delete it later, choose it, then open the menu again and choose Edit.
Can I see note names another way?
Yes. In the tuner's settings, Note Names switches between English (C D E), solfège (Do Re Mi) and German (with H), and Accidentals shows sharps or flats. You can also show the string numbers and the octave on each string button.
Does the metronome keep playing with the screen locked?
Yes, and while you use another app. It stops if a phone call or alarm takes over the sound. Turn on Flash on Beat or Haptics from the metronome's settings button to see or feel the beat too.
Why doesn't my screen dim?
Tuneshed keeps the screen on while it's open, since you'll usually have your hands on the instrument. It dims and locks as usual once you leave the app.
It says the microphone is off.
Open Settings → Apps → Tuneshed and turn on Microphone. The metronome works without it.
