For patients and families

Less effort. More of the day on record.

Keeping a health diary is hard. Rerio uses ambient audio sensing to pick out things worth noting: a medication you mention, a headache, a meal. You simply confirm with a tap instead of writing it down.

Join the beta list How does ambient audio work?

In developmentAudio events are an early prototype we’re testing now. Reminders, check-ins, activities and wearable data are in the app today.

In the app

Most of it happens in the background.

Listening runs in the background. The rest takes a few minutes a day: your medications, one short activity and a check-in. Pick a screen to see it.

Audio events in the Rerio app for Friday, October 16. Seven events to review: aspirin, reported taking; headache, reported mild; anxious, reported feeling; a cough; cutlery sounds; a possible meal from chewing and cutlery sounds; and possible toothbrushing from electric toothbrush sounds.
Medications today in the Rerio app: Memantine 10 mg taken at 9:00 AM, with Donepezil and Memantine still due at 8:00 PM. One of three recorded.
The Spatial Path activity in the Rerio app: an example of the task, the instruction to tap the locations in reverse order, and a Begin practice button.
The daily check-in in the Rerio app: three questions, how did you sleep, how is your energy and how are you feeling, each answered on a scale of five faces.
Screenshots from the Rerio app. The account and medications are examples.

Audio events In development

You talk. Rerio takes the notes.

Start recording on your Watch and go about your day. Rerio picks out what’s worth noting and shows you what it heard. Nothing is added to your record until you confirm it.

An audio event in the Rerio app: a medication report for aspirin, recorded Friday, October 16 at 9:00 AM. It shows the quote “I took aspirin” with a short cleaned clip to play, what Rerio picked up (dose, strength and route not stated), and buttons to confirm, edit details or reject.
Something you said
An audio event in the Rerio app: a possible meal at 9:05 AM, marked experimental. It lists the sounds detected, chewing and cutlery, with a clip to play, explains that it is an approximate estimate that doesn’t count meals or show what was eaten, and offers confirm, change activity or reject.
Something it heard

  1. Things you mention

    “I took my aspirin.” “I’ve got a bit of a headache.” Said in passing, picked up as a medication or a symptom.

  2. Sounds around you

    Chewing and cutlery, an electric toothbrush, a cough. Ordinary routines show up without anyone writing them down.

  3. You check every one

    Play the clip, then confirm, correct or reject it. Names and other identifiers are muted in the clips.

  4. Only when you choose

    Recording starts when you start it on your Watch, and needs your consent first. You can delete the audio at any time.

With your doctor In development

Rerio does the homework. Your doctor makes the call.

Between visits, Rerio’s AI keeps working through everything you record. It looks for changes from your own normal, investigates what might be behind them, and keeps checking whether a different treatment approach could suit you better. What it finds goes to your doctor with the evidence attached, so each appointment starts from the full picture.

  1. Spots what’s unusual

    A run of poor nights, missed evening doses, a routine that shifted. Rerio compares each day with your own normal, not with an average patient’s.

  2. Looks into why

    It lines a change up with everything else from those days: check-ins, wearable data, what you mentioned out loud and your medications.

  3. Keeps looking for better options

    It keeps checking whether a different treatment approach might work better for you, learning from you and people with similar histories.

  4. Shows its working

    Every finding reaches your doctor with the records and research behind it, and what’s still unknown.

Your doctor makes every decision. Rerio never changes your medication or your plan on its own. It makes sure your doctor has what they need to decide.

How it works for clinicians

Your records

Your records, your choices.

Using the app and taking part in research are separate decisions. You can do one without the other.

Where your records are kept

Your records are stored in your Rerio account and kept on this device so you can record offline.

Research is a separate choice

Taking part in research is entirely optional. It’s only switched on with your explicit permission, and saying no doesn’t change how you or your doctor use Rerio.

Patient app beta

The Rerio app is coming to beta soon.
