B1 is a small green square who lives in your chat. Type, or talk out loud and B1 talks back. B1 thinks while you wait, speaks as the answer arrives and looks puzzled when something goes wrong.
The Desk scene, with its focus timer. Tap Talk to B1 and speak; B1 talks back.
No spinner, no dots. B1's face tells you what the AI is doing, and reacts when you tap, stroke, tilt or shake.
Looks up and away while your question is with the AI.
The mouth moves in time with the words as they arrive.
A happy moment when the answer is done.
If something fails, B1 says what happened in one plain line.
B1 is a proper assistant. It knows the time, can check the weather, look things up, keep your list and read your day back to you. Each of these is yours to switch on or off.
Every chat knows today's date, the time and your time zone, so "what's the date a week on Friday?" gets a straight answer.
Ask about the weather or what to wear and B1 answers from Apple Weather. It's off until you switch on Real weather, and only your rough location goes to Apple.
With OpenAI, Claude or Gemini connected, B1 can search the web and lists its sources as links. Searches use your own key, and there's a switch to turn them off.
Say "remind me to take my tablets every day at 8" and it's on your list, with a nudge at the right time. Daily, weekday, weekly and monthly repeats. The list never leaves your iPhone.
Let B1 see your calendar and it can tell you what's on today and mention an appointment that's about to start. Read only: B1 never changes your calendar. Off until you switch it on.
Once a morning, a short hello with today's appointments and what's on your list.
Speak and B1 speaks back. Your speech is turned into words on your iPhone, and the answer is read in Apple's voices.
Attach a photo for brains that can read one. Replies show headings, lists and code properly, and you can copy, share, stop or ask again.
B1 is an AI. Replies can be wrong, so check anything important.
Prop your phone up and B1 keeps you company, dressed for the real weather outside and for special days. Tap Talk to B1 in any of them to chat out loud. All eight scenes are free.
Listens along to what you're playing.
Dozes off, and dreams.
Settles in for an episode.
Drifts among the stars.
Under a blanket, watching the rain.
A focus timer to work beside.
Slow breathing before bed.
Grows a little every day.
The window always shows the real time of day: dawn, daylight, dusk or a night sky with the moon. A little clock beside it shows the real time.
Switch on real weather and the window shows rain, snow, cloud or sun as it is where you are, and B1 dresses for it: a scarf when it's cold, sunglasses in bright sun, an umbrella in the rain. Only your rough location goes to Apple Weather.
The scenes do things too: Desk has a focus timer, Wind-down guides slow breathing, Sleep has dreams, and the Garden grows a little each day.
Free widgets put B1 where you'll see it without opening the app. Tap one and you're in Ambient Mode.
A small dashboard made for CarPlay: B1 driving a little car, with the time and the temperature. The sky follows the real sunrise and sunset, and the real weather if you've switched it on. Nothing to read but the time and the temperature.
B1 beside an alarm clock, with the real sky and weather through the window. Small or medium.
B1's mood for the time of day on your Home Screen and Lock Screen, and a bedside clock for StandBy.
The focus timer and what's playing show on your Lock Screen and in the Dynamic Island.
B1 works the moment you open the app. For the best answers, bring your own AI key: it takes a minute, and B1 can then use the most capable models there are.
The best way to use B1
A key (an "API key") lets B1 talk to a cloud AI on your behalf: OpenAI, Claude from Anthropic, Google Gemini, or any service that speaks the OpenAI format. Answers are sharper, longer and better informed than a phone can manage alone.
You pay that service directly for what you use, and nothing goes to us. Your key stays in the iPhone's Keychain and is sent only to the service it belongs to.
Free, and ready from the start
Apple Intelligence runs on the phone itself. No key, nothing to set up, and your words stay on your device. It is a small model: good for quick questions, with a short memory.
Your own kit
Ollama or LM Studio over your home network, or your own VPN when you're out. No key needed, and nothing leaves your own machines.
Prefer to talk? Tap Talk to B1 and have the whole conversation out loud. Your speech is recognised on your iPhone, and B1 answers in a voice.
Chat, voice, the eight scenes and every widget cost nothing. Other avatars are bought once and kept for good, and each works everywhere B1 does.

Each avatar is £2.99. The Starter Pack has all eight for £14.99. Your avatar shows everywhere: in chat, in every scene and in the widgets.
Everything in the shop can be previewed, and tried in a scene for 30 seconds, before you pay anything.
No subscription. Family Sharing is on for everything. Nothing you need is locked: chat, voice, the eight scenes and the widgets are free.
Festive snow, £0.99: gentle snow past B1's window in December, or all year if you like. It never falls over real rain or real snow.
New things arrive with app updates through the year, a pack at a time. None of what follows is on sale yet, and none of it is needed: it is all for fun. The pictures here are drawings, not screenshots.
Winter, Garden, Snack, Spooky, Pets, Farm, Wild, Ocean, Space and Legends. A pack of four is £9.99, or £2.99 each. Each has its own dreams and its own way of talking.
Six packs, each with a hat, glasses, something for the neck and something to hold: a crown and cape, a safari hat and compass, a bobble hat and lantern. Four pieces for £2.99. They fit every avatar and can be mixed. What B1 wears for the real weather stays free.
Seven places, lit by the real time of day, and three for winter: Christmas, Snowy cabin and Sleigh ride. £2.99 each. A crackling fire for the cosy scenes is coming too. The eight scenes the app starts with stay free for good.
Your chats are stored on your iPhone. Before anything is sent to a cloud AI, B1 tells you who it goes to and what is sent. And B1 is an AI, and says so.
