Talk to SyncSessions.
Ask Siri to make a group, propose a session, or change your profile, without opening the app and finding the right screen.
Every command works on iPhone, iPad and Mac.
Eight commands are ready to say out loud, out of the ten Apple allows any app. Anything else, you can name yourself in Shortcuts.

Every command has to name the app. That is how Siri knows "set my color to green" is meant for SyncSessions and not for something else, and there is no way around it.
Four names work, and they are interchangeable:
| Say | Which is |
|---|---|
SyncSessions | The app's own name. |
Sync Sessions | Two words, the way most people say it. |
Sync | The short one, when you want to be brief. |
SS | Shorter still, and the least reliable of the four — two letters give Siri very little to recognise. |
Below, [app] stands for whichever of the four you prefer.
Siri does not remember which app you were talking to. Each separate command needs the name. A follow-up within one command does not — after "Add a SyncSessions group", you simply answer "Pink Flamingo".
Want something shorter still?
Make a shortcut in Apple's Shortcuts app and name it anything you like. A shortcut's name is its own trigger, so it needs no app name at all — "new band" on its own can work.
Creating a group needs a Leader subscription. Everyone you invite joins free.
The session is proposed the way the app proposes one: two hours long, looking for a slot from tomorrow through the following week. Your bandmates are then asked when they are free. Only a band's leader can propose sessions.
If two of your groups have similar names, Siri asks which you meant rather than guessing.
Your color is what identifies you on the availability grid. Twelve to choose from: Red, Orange, Yellow, Green, Mint, Teal, Cyan, Blue, Indigo, Purple, Pink and Brown. Say the color's own name — "violet" will not find Purple.
Forty-two to choose from, covering strings, keys, wind, percussion and vocals, as well as the people who are not playing: DJ, Producer, Conductor, Arranger, Sound Tech, Video Tech, Roadie and Crew — and plain Musician, which is what a new profile starts as until you say otherwise. You can list up to five.
This is the name your bandmates see.
These are the calendars SyncSessions reads to work out when you are busy. It never reads the events themselves — only whether a time is free.
SyncSessions has to already have permission to see your calendars. A voice command will not ask for it, because a permission request deserves a screen that explains itself. Grant it in the app once and the command works from then on.
The app opens. Every command opens SyncSessions, so you can see what happened rather than take Siri's word for it.
Nothing is deleted by voice. There is no spoken command that removes a group, a session or a member. Those stay in the app, where you can see exactly what you are removing.
Some things are a question and an answer. Anything you invent — a band's name, a session's name, your own name — cannot be part of the first sentence, because Siri matches what you say against things it already knows. So it asks, and you answer. "Add a SyncSessions group" → "What should the group be called?" → "Pink Flamingo".
Apple gives every app ten ready-made Siri phrases. Not ten for SyncSessions — ten each, for every app on your iPhone, so that no one app can lay claim to a large share of what Siri listens for. It is a fixed ceiling, and the same one Apple's own apps work within.
SyncSessions spends eight of its ten on what is worth saying mid-conversation: starting a band, proposing a session, and the profile settings you change often. Two are deliberately unspent, because a phrase is worth adding only when there is something people actually want to say.
The ceiling only applies to the ready-made phrases. Everything SyncSessions can do appears in Apple's Shortcuts app, and there is no limit there at all. Add any command to a shortcut of your own, name it whatever you would actually say, and Siri answers to that too — a shortcut's name is its own trigger, so it needs no app name. "New band" on its own can work.
That is also the answer if a command you want is not spoken here: you can add it yourself in about a minute, and name it better than we would have.
