Most health apps see a slice. Savva sees the whole body.
Your labs live in MyChart. Your sleep lives in Oura. Your cuff lives in Omron's app. Your glucose lives in Dexcom. Your medications live in a pharmacy PDF. You live across all of them, and no one has put them together in a way that actually helps you understand what's happening.
Savva does. Your last fifteen blood pressure readings, your HbA1c trend since 2009, your Wegovy titration schedule, your respiratory rate last night, your UCSF visit notes from 2014, and an AI that can reason across all of it. On your phone. Without an account.
Because the people who understand their body best tend to live the longest.
AI
Every reading, every source, one chart.
Reliable readings done the AHA way. Home cuff, Apple Watch, clinic visits, and lab PDFs land on the same timeline. Snap your monitor with the camera and skip the typing.
AHA protocol built in: 5 minute rest, two readings averaged
Home cuff, Apple Watch, clinic visits, and scanned PDFs on one chart
Point your phone at the cuff display to skip typing and avoid data-entry errors
Every reading on the chart is ringed by source, so you always know where it came from
Trend lines you can act on
AI
When weight bends, the reason is on the chart.
Log your weight and your GLP-1 dose in seconds. See both on the same curve. Know how much you lost or gained this month, last month, and the three before.
Two-tap dose logging for every common GLP-1
Dose changes appear as dashed lines right on your weight curve
Plain monthly numbers, not a smoothed graph you have to squint at
Home-screen widget for a weigh-in or a dose without opening the app
Body composition (BMI) trends on the same view
AI
Real CGM data. No smoothing. No fake lines.
Your CGM graph shows raw sensor data alongside the meals you logged in Savva or saved to Apple Health. So you can see exactly which foods and habits are moving your glucose.
Every meal paired with the glucose reading two hours later
Lock-screen shortcut and home-screen widget for one-tap meal logging

Your Full Medical Timeline
Everyone's health history lives across providers. UCSF for the last decade. Ohio State before that. Mayo for the surgery in 2002. Urgent care visits on vacation. Lab printouts from the doctor your employer switched off. Savva pulls all of it, from 280,000+ US clinics and hospitals, into one timeline on your phone.
From your providers
Direct EHR sync
Connected to EHR systems serving 280,000+ healthcare providers across the U.S. Your records flow in automatically.

From paper, photos, or PDFs
Scan any document
When you snap a picture of the document that you received from the clinic or use a PDF that was sent to you, Savva utilizes OCR (optical character recognition), that will read the text from the picture or document. We support your native language and this entire process happens all on your phone.
We don't stop at OCR, we go beyond and use your chosen AI to structure the data so that it's available in charts, biomarkers, and more in the app. All biomarkers, vitals, medications, conditions, procedure, and notes are organized for you.
Connected to leading wearables and fitness apps.
Steps, exercise minutes, calories burned, stand time, distance, sleep stages, and heart rate zones flow into Savva automatically and live next to your medical records.
Every AI has a personality. Pick the one that fits you.

Why Savva?
Most health apps see a slice. Savva sees the whole body. Here's how the leading alternatives compare.
AI chatbots
ChatGPT Health, Amazon Health, Google
AI Chatbots pull your records into a server, give you a chat bubble, and wait for you to ask it a question.
Savva
Your records are curated with biomarkers, charts, visit history, and more. AI gives you insights and a full chatbot.
Wearable apps
Oura, WHOOP, Garmin
Wearable Apps give you scores and numbers for only their device. No medical record context.
Savva
Your sleep score on the same timeline as your HbA1c, your UCSF notes, and your Wegovy doses.
Record aggregators
Apple Health, MyChart, Healthview
They aggregate records from multiple sources, leaving you to navigate the app to find the data you're looking for.
Savva
12+ AI models on tap. Ask any of them anything. Switch for more opinions.
Savva does it differently
Your medical records, fitness data, and AI analysis together on your phone. No account. No cloud. The only safe choice in modern consumer health AI.

Your data isn't de-identified. It's unidentified.
Most health AIs claim "de-identification." But if they need your name, email, and birthday just to start, what exactly did they de-identify? Savva requires no account. No sign-up. No identity on file. Nothing you do in the app is tied to a user record, because there is no user record.
Everything stays on your device. AI runs on your phone when you pick on-device. When you opt in to cloud AI, your data travels only for the duration of the query, and only to the provider you selected. There is no Savva cloud storing your records because there is no Savva cloud.
And the cloud provider doesn't know who you are. Every query goes out under one shared Savva API key. To them it's anonymous traffic from a single app, with no individual identity to build a profile around.
On-device storage
Medical records and fitness data stored locally on your phone. Not on a server.
No account required
Use Savva without creating an account or sharing personal info.
AI that runs on your phone
Pick from on-device AI models like Llama and Gemma. They download to your phone and analyze everything locally. Your data never leaves the device, ever.
