01
Speak while it is fresh
Hold to talk and describe the day naturally. Daymark keeps the original transcript visible throughout review.
Stage Zero · Native capability proof
Record the day. Never rewrite the truth.
Daymark is a privacy-first mobile evidence diary for people documenting how health conditions or disabilities affect daily life. Speak naturally, review every structured detail and keep your own words in control.
Independent of GOV.UK and DWP. Not medical, benefits or legal advice.
What to expect from Daymark
Your words
Original transcripts remain visible, and structured entries require approval.
Local first
No mandatory account, advertising SDK or sale of sensitive diary data.
Portable by design
The native repository must remain buildable for iOS and Android without Daymark’s development team.
The core workflow
Ten seconds to an entry you can trust.
The first build proves the difficult parts before retail development begins: native delivery, private voice capture, faithful structuring and evidence integrity.
The non-negotiable rule
AI may organise a statement. It may never add a symptom, strengthen ambiguity, calculate entitlement or suggest what the user should say.
02
Approve every structured entry
AI organises only what was said. Nothing becomes final until the user has checked, edited and approved it.
03
Trace patterns to their source
Factual frequency summaries link directly back to the diary entries behind every count.
04
Keep sensitive data private
A local-first architecture, app lock and clear processing consent minimise unnecessary exposure of health information.
Stage Zero handover
Six proofs, then stop and report.
Architecture, privacy threat model, native build proof, clickable core UX, voice-to-diary prototype and hallucination test suite.
