A medical history that stays together

Justin and Karen Baker wanted to make managing health information easier for people living with chronic illness. Records were scattered across appointments, documents and different providers. MedVault brings that information into a personal record the user controls.

We designed and built the app in React Native. It is available on iPhone through the Apple App Store.

Ready for the next appointment

Conditions, medications, allergies, procedures, care teams and test results live alongside the user’s documents and profile. Users can prepare a summary of their records, review it and copy it into a form or take it to an appointment.

The interface keeps navigation clear, text readable and primary actions easy to find. The aim is to make everyday record-keeping manageable even when someone has little energy to spare.

All entered data is envelope encrypted

Encryption covers all data a user enters, not just free-text notes. We implemented envelope encryption with password-protected keys: data is encrypted before storage and decrypted on the user’s device.

The database stores the encrypted information. Access to readable records stays tied to the user’s keys, rather than relying on database access controls alone.

AI only with permission

MedVault integrates with AWS Bedrock to access Anthropic’s Claude models for optional summaries. Before a request, the app explains what information will be sent and lets the user inspect it, cancel or explicitly permit processing.

With that permission, the selected information is sent for AI processing. It is not used to train models. The result is returned for the user to review before saving or sharing. This is help organising existing records, not medical advice or diagnosis.

What users say

“I’m really impressed with MedVault. It was so easy to set up, and the app is very straightforward to use. The layout is clean, simple, and easy to navigate. It’s a great way to keep all my medical information organised in one secure place, so I always have it available when I need it.”

“MedVault is a great app that makes going to appointments and making sense of reports super easy. My personal favourite feature is the ‘prepare for appointment’ option which makes sure you don’t get those “Oh I forgot to mention xxx at the doctor”.”
