B1 Buddy support

Last updated: 14 November 2026

Getting help

Email support@b1buddy.app. In the app you can also open Settings (the cog on the chat list), then "Email us". Please say which iPhone or iPad you have, its iOS version, and the app version (shown in Settings, under About). Never send us an API key.

To report a reply from B1 that was wrong or upsetting, press and hold the reply and choose Report this reply. This opens a draft email in your Mail app with the reply in it; you can edit it, and nothing is sent unless you press Send.

B1 is an AI. Replies can be wrong, so check anything important. If you or someone else is in danger, contact your local emergency services.

Common questions

How do I add a brain (an AI service)?

Open Settings, then B1's brains (it uses your buddy's name), then Add a brain. Choose OpenAI, Claude (Anthropic), Gemini (Google), "Another service" (any service that uses the OpenAI format) or "My own computer" (Ollama or LM Studio at home). Paste your own API key from that company's website, test the connection, pick a model from the list and save. The first time you chat with it, B1 shows a screen saying what will be sent to that service; nothing is sent unless you agree. Using a service with your own key may cost you money with that company; B1 Buddy does not charge for it and unlocks nothing with it.

"The model on this iPhone isn't available"

The free brain that runs on the device is Apple's on-device model, part of Apple Intelligence. It needs an iPhone or iPad that supports Apple Intelligence, with Apple Intelligence switched on (Settings, Apple Intelligence & Siri). After switching it on, the model may take a while to download; leave the device on Wi-Fi and charging, then try again. If your device cannot run Apple Intelligence, add another brain instead (above).

How do I restore my purchases?

Open Settings and tap Restore purchases, or use the button at the bottom of the shop. Sign in with the same Apple Account you bought with. Purchases are shared with your Family Sharing group. B1 himself, chat, voice, the widgets and the eight scenes are free and never need restoring.

How do I delete my data?

Everything is kept on your device; we hold nothing.

• A chat: swipe it to the left in the chat list and choose Delete.
• A brain and its key: Settings, B1's brains, tap the brain, Remove this brain.
• Stop sending chats to a service but keep it: tap the brain and choose Stop sending chats here. B1 asks again before sending anything there.
• Everything: remove your brains first (iOS may keep saved keys after an app is deleted), then delete the app.

What a service has already received is held by that service; ask them about it. Full details: the privacy policy.

My computer at home isn't found

Make sure the phone is on the same Wi-Fi as the computer, that Ollama or LM Studio is running, and that it is set to accept connections from other devices on your network (the app explains the one setting to change). If iOS asked to find devices on your local network and you said no, turn it back on in Settings, Privacy & Security, Local Network, B1 Buddy.
