No backend
No login, no server. Records live in an encrypted SQLite database on your iPhone, gated by Face ID. If your phone is off, your family's data is unreachable.
Your family's health,
on this device.
A personal health app for one operator on one iPhone — managing self, kids, and aging parents without an account, without a cloud, without ads.
Why on-device
The opposite of a cloud health app.
Most consumer health apps push your data through transcription vendors, foundation-model providers, and behavioral advertising stacks. prajna doesn't. There is no backend, no account, and nothing leaves the phone you read this on.
On-device transcription
Visit recordings are transcribed locally with WhisperKit. The audio never leaves the device, and the transcript is yours alone — no vendor seat to revoke.
Redacted Q&A
The only outbound call is a redacted question to the Claude API when you tap a finding to ask about it. Identifiers are stripped client-side before the request is made.
Sharing without sharing
Keep mom or a sibling in the loop with pre-visit briefs and post-visit recaps sent via iMessage or Mail. No second-user app to install. No data round-trip through a platform.
What it does
One operator. One device. The people you care for.
Ingest
Apple Health Records, MyChart CCDA bundles, and PDFs of printouts. Every observation is
traced back to its source document. Vision extraction is verified before it counts.
Capture
Four visit modes — live recording when consented, a structured live-note when not,
post-visit dictation, or a photo of the printed visit summary. All feed the same
summary + action items pipeline.
Track
Trended metrics with reference ranges and annotations. Age-, sex-, ethnicity-, and
relationship-aware screening cadence for each profile.
Ask
Tap any finding to ask about it. Answers are grounded in the managed person's own
history, with identifiers redacted before the request leaves the device.
Carry forward
Concerns persist across appointments. Open questions don't vanish between visits, and
follow-ups land on the next appointment automatically.
Status
In private beta.
prajna is in friends-and-family beta on iPhone (iOS 26). If you manage health records for people you love, leave an email and we'll be in touch when the next slot opens.
We'll only email you about beta access. No newsletter, no list rentals, no analytics pixel.
