HAIVault

Coming soon · invite-only alpha

Log daily.
See your trends.

Capture sleep, recovery, meals, symptoms, medications, and lab results in one place. Review them over weeks and months, then bring a clearer history to your next doctor visit.

Invite-only alpha is iPhone-first and needs a recent iPhone with Apple Intelligence (on-device AI). Not on the App Store yet.

On-device AI is part of HAIVault — it helps you capture and make sense of your diary without sending health data to our servers.

Everyday use

One diary for the day you actually had.

Today is a short check-in — type or speak. Blank fields stay blank, so a partial morning still saves.

  1. 01

    Check in

    Sleep, activity, meals, symptoms, and how you felt.

  2. 02

    Keep context

    Medications, appointments, and lab readings sit beside the day.

  3. 03

    Look back

    My Trends turns weeks of entries into charts you can review.

On-device AI

Intelligence that stays with your diary.

HAIVault uses AI on your device to speed capture and turn messy days into something you can review — while health data stays local.

Faster capture

Speak or type a natural check-in. On-device AI helps sort meals, drinks, metrics, and symptoms into the right places.

Photos that become logs

Point the camera at a meal or a medication label. On-device AI drafts structured entries you can review before saving.

Visit-ready clarity

Turn weeks of diary entries into plain-language summaries and visit prep — generated on your device from your own data.

Private by design

On-device AI is how HAIVault gets smarter without building a cloud of your health records. You stay in control of what is saved. It supports reflection and visit prep — it does not diagnose or replace clinical care.

Alpha testers need an Apple Intelligence–capable iPhone (roughly iPhone 15 Pro or later), with Apple Intelligence turned on and the on-device model ready.

Who it’s for

Built for the stretch between visits.

Especially useful if you already track something — and still arrive at appointments with incomplete recall.

Recurring symptoms

Keep severity, notes, and timing in one place so patterns are easier to discuss.

Home metrics

Sleep, weight, blood pressure, and recovery — logged beside the rest of your day.

Personal experiments

Try a change, watch your own baseline vs experiment window, and bring a clearer story to your clinician.

Clear limits

What HAIVault is not.

  • Not a medical device
  • Not a diagnosis or triage tool
  • Not your clinic’s EMR or a replacement for clinical care
  • Insights show personal associations — not proof of causation

HAIVault is a private diary and reflection aid, meant to help you prepare for conversations with your clinician.

Privacy first

Your diary lives in a local vault.

Health data stays on your device. The core app is designed so you can keep a diary without uploading health records to HAIVault servers.

On-device AI runs with the diary on your device — from check-in help and photo capture to visit prep — so intelligence does not require uploading your health records to HAIVault servers.

On iPhone, you can choose which Apple Health metrics to sync. Metrics you leave unticked stay editable in HAIVault.

Short privacy note
