Memory that stays yours: About you, History, the knowledge graph, Get to know me.
Apps: Maps, Weather this week, Gallery, workout images.
With Halo glasses: marked as sold separately.
You stay in charge: senses, account, clear error messages.
Good to know: iOS 26, model sizes (about 0.8 GB, or 2.3 GB on 8 GB iPhones), what goes online, and Apple’s standard warning about background GPS draining the battery.

## Version history (last 5 releases)

### 2.4.0 — 2026-10-29

• Santos in 3D: in You, Santos' look, Santos stands in own scene, by day or by night, breathes, looks around and turns when you drag
• Pick one of seven helmets for Santos and colour it like the rest of the outfit
• Wearing Halo or Frame? Santos follows your head as you turn, nod and tilt. Halo's compass can now be calibrated while you wear it
• Your data now covers everything Santos keeps, including your paired devices, and exports and restores all of it
• Faster answers: a question no longer waits for Santos' background work

### 2.3.0 — 2026-10-28

• Make Santos yours: pick Santos' colour and the colours of the tee, vest, shorts, socks and sneakers in You, Santos' look. Shading follows your colours, and one tap brings back the original look
• Inputs and outputs show only the glasses that are connected, in Talk, Devices and the Gallery. A pair you picked comes back as soon as the glasses reconnect, and Open Devices takes you there to connect one

### 2.2.0 — 2026-10-27

• Offline mode: turn it on in You, and Santos' own features stop using the internet. Talk, Memory and the glasses keep working on your iPhone
• Santos keeps its brain and voice after updates: no more download prompt for models already on your iPhone, and the voice stays even when the iPhone is low on space
• Takes less space: an upgraded brain offers to remove the old one, chat photos are stored smaller and leave with their chat, and Halo battery history keeps 90 days
• Downloads check for free space first and tell you how much they need
• Santos noticed: Santos looks through your history for things it shows about you, like places you return to and your routines, and you choose what it keeps
• Rate Santos' answers with a thumbs up or down and say what went wrong. Santos learns which tools to reach for, and your ratings stay on this iPhone
• Import a WhatsApp chat into History: share it to Santos, say which sender is you, and Santos noticed suggests what it shows about you
• Control your Samsung TV by voice: volume, channels, apps like Netflix and YouTube, and turning it off. Pair it once in Devices, TV, and it stays on your home Wi-Fi
• For tinkerers: Developer options now has Answer settings, to tune how the on-device model writes (temperature, length, sampling and penalties), with a plain explanation for each

### 2.1.0 — 2026-10-27

Santos 2.1 links what it knows about you to the rest of your iPhone.

• Use Santos without an account. Sign in only when you want Habit Tracker or connected apps
• Link an About you fact to a habit in Habit Tracker, or create the habit right there. Santos reminds you before your usual time and skips days you've already done
• Link a fact to a Calendar event and get a reminder 30 minutes before it starts
• Habit reminders are check-ins: tap Done to mark the habit done, or open Santos to say what time you did it
• Reminders show on Halo or Frame too, and a gesture you choose marks a habit done from your glasses
• Or have a reminder run a Shortcut or open a link. Share any fact with other apps
• Memory: a new Vectors view, ask about a memory through Talk, and swipe to forget
• Better answers from memory: Santos recalls more and says when it doesn't know
• Santos' voice now reads numbers, prices, percentages and dates naturally
• Your data: see what Santos keeps on this iPhone, export it, and choose what goes into iCloud backups (off by default)
• Moving to a new iPhone? Import your Santos export there, and your memory, chats, photos and routes come with you
• Delete your account with a clear choice: export, keep or delete your data on this iPhone
• Maps: send a route to your Tesla from the share sheet
• HeatLoad for Airtech accounts: create and edit a heat-load study in Talk with a step-by-step form. Pick a product and its thermal values fill in
• See the refrigeration capacity at a glance, with a breakdown per load, and export the study as a PDF to preview and share
• Ask how you slept: with the Health sense on, Santos reads your sleep and recovery from Apple Health, on this iPhone only
• Talk: taking a photo with the iPhone camera works again

On-device only (cloud chat removed).
