Walk in. Know the room.Do what you came for.

Fathom is an AI companion for blind and low-vision people. Most places were built without you in mind. Fathom tells you what's around you, walks you to where you're going, and works through the task with you. On your iPhone. No maps, no beacons, no setup.

The gap

Indoors, you're
on your own.

GPS ends at the door. Inside, nothing tells you which way the counter is, what the sign says, whether that seat is taken, how the kiosk works, or where to sign. So you ask, or guess, or bring someone. Every unfamiliar place costs you some independence before you've done a thing.

Fathom gives you the room: what's in it, where things are, what the words say, and what to do next. Anywhere, your first time in.

Home

Five modes.
One calm surface.

Fathom opens on a single screen with everything a step away. Snapshot for a quick look. Lookout for ongoing awareness. Go for navigating to a place. Task for step-by-step help with what you're doing. And the Assistant, one tab over, for when you'd rather say the goal and let Fathom choose.

Each mode is designed to do one thing well — so you never have to think about which button to press, just what you need right now.

Lookout

Silence
means safety.

Lookout is your always-on safety companion. It watches continuously but only speaks when something matters — a step down ahead, a glass door, a person on a collision course. When Fathom is quiet, you know the path is clear.

An Awareness setting sets how much you hear: Hazards Only, Balanced or Full Awareness. Haptic alerts fire in under 100 ms when something's close.

On-device object detection, several times a second. Works without a network.

Point to ask

Point at anything.
Fathom names it.

Hold your arm out and point for about a second. You feel a tap, hear the earcon, and get the answer in three parts: the thing in a few words, any words on it read exactly, then where it is and what's around it. Sweep your finger to something else to hear about that too.

A vending machine.

Buttons read: Water, Cola, Coffee. Coffee is sold out.

Card reader on the right side, about three feet away.

LiDAR measures the distance to what you're pointing at, so Fathom describes what is there rather than what it expects. Hands-free in Lookout and Go; from the Snapshot menu anywhere.

New in 1.2.0. Free.

Snapshot

One look.
Five ways to ask.

Snapshot describes what's in front of you. Open its menu and it can also read text, identify an object, answer a question about what's in view, tell you what you're pointing at, or read a digital screen: the display type first, then its layout, then what it says.

All five are free.

Go

Turn-by-turn
indoor navigation.

Say where you're headed — “the kitchen,” “Room 412,” “the pharmacy” — and Fathom gets you there. It reads room numbers and signs as you pass them, calls turns before you need them, and tells you when you've arrived, down to where the door handle is.

Directions use a clock-face system: “door at 2 o'clock, about 25 feet.” Obstacle alerts pulse faster as you approach, so the space has a shape you can feel in your hand.

On-device depth sensing and AI vision, together.

Task

A real-time companion
for the task at hand.

Task guides you one step at a time: folding laundry, finding the milk, sorting paperwork, working through a kiosk. Live Task makes it a conversation. Hold to talk, and Fathom answers from what's actually in front of you, at the speed of your hands.

Live Task streams audio and video both ways. It's in beta.

Assistant

Describe a goal.
Fathom handles the rest.

Tell the Assistant what you want to do — “get me to my 3 o'clock on the fourth floor” — and it figures out the path. Lookout walks you in. Go takes you to the elevator, then the suite. Task checks you in at the desk.

You never think about modes. The Assistant understands intent, breaks it into steps, and orchestrates everything Fathom can do.

Activities

Not sure where
to start?

Tap Activities for a short menu of the things Fathom does well — find something, orient yourself, go somewhere, work on a task, read something, use a kiosk.

It's a guide rail, not a wall. Pick an activity and Fathom tailors the rest of the flow around it.

Ask Fathom

Or just say it
in your own words.

Hit Ask Fathom and talk. “Organize my mail.” “Find the oat milk.” “Check me in at the pharmacy desk.” Fathom listens, parses intent, and starts building a plan.

On-device speech. No wake word required.

The plan

A plan you can
see before you start.

Fathom thinks for a moment, then shows its work: a short ordered list of steps, each labeled with the mode that will handle it — Go, Snapshot, Task.

Accept it as-is, edit a step, or dismiss and try again. Nothing happens until you say go.

Active session

One step at a time,
hands free.

Once you accept, Fathom runs the plan step by step. Each screen is focused on one thing — walk here, look at this, do that — and Ask Fathom stays within reach if the world changes.

End the session any time. Move on with a tap, or shake when a step is done.

Day one

A pair of eyes
looking out for you.

Fathom watches the room so you can get on with being in it. It tells you who's coming toward you, reads the sign you can't see, finds the counter, and stays with you through the form or the kiosk. Nothing installed in the building, nothing to configure. Open the app and it's already working.

In a basement, in an elevator, with no signal at all, the part that looks out for you keeps running: on-device detection, LiDAR, and every safety alert. Your safety never waits on a network.

Day to day

Built for how you
actually use it.

Cues you feel

A tap for a hazard, a pulse that quickens as a wall gets close, a pattern of its own when you've arrived. Sound comes from the side it's on. You learn the vocabulary in a week.

Quick answers

Ask Fathom in any mode: what does that sign say, is this seat taken, which way is the counter. One question, one answer, from what the camera sees right now.

Help with the hard parts

Say the goal. The Assistant makes a plan, hands each step to the right mode, and walks you through it. Live Task stays on the line while your hands are busy.

It knows you

Tell Fathom once how you see, what you walk with, and your guide dog's name, and every answer accounts for it. Say “forget that” and it's gone. It all stays on your phone.

VoiceOver is a first-class citizen, not a retrofit. Low vision isn't a lesser version of blindness: high contrast, large targets, and it works without VoiceOver when you have the light for it.
