For health-tech and mental-health founders
A health app prototype people can test, built on synthetic data
Put a working version of your health or mental-health product in front of users, clinicians and investors before any real patient data is involved. We build it clickable or coded, run it on synthetic, non-sensitive data, and scope it around the questions your next milestone depends on. You learn what works in people's hands while the regulated parts of the product are still on paper.
What you get
What’s included
Clickable or coded, matched to the test
A clickable prototype for fast usability rounds and investor demos, or a coded one when testers need real interaction, such as typing a journal entry or completing an intake form. We recommend one based on what you need to learn.
Synthetic, non-sensitive data throughout
Every screen runs on realistic made-up profiles, entries and histories. No real health information is collected or stored, so the prototype stays outside regulated territory.
The flows your milestone depends on
Onboarding, the main thing users come back to do, and the screens a tester or investor needs to understand the product. Agreed in writing before design starts.
Ready for testers and investors
Set up so testers, clinicians and investors can open it on their own phone or laptop during sessions and meetings.
Boundary notes for the real build
A short written list of where the production product will touch sensitive data, clinical workflows or crisis features, so each one can be planned with a specialist owner before the MVP is quoted.
Handover of the work
Design files and any prototype code handed over at the end, so the MVP build starts from what you already tested.
A good fit if
- Founders raising a round who want investors to tap through the product themselves
- Teams that need clinician or advisor feedback on the flows before paying for a build
- Mental-health and wellness products that need usability testing before real user data is involved
- Founders who finished a planning sprint or blueprint and want to test the scope before funding the MVP
Not included
- Real patient or user health data, in any form
- Clinical validation, regulatory review or compliance sign-off
- A production backend, live user accounts or an app-store release
- Working crisis, diagnosis or treatment features that would need a clinical owner
How it runs
From kickoff to handover
- Step 1
Agree what the prototype must prove
We pin down the questions first. Will people finish onboarding? Does the daily check-in make sense? Can an investor follow the product without a walkthrough? The scope follows from those answers.
- Step 2
Design the flows on synthetic data
Screens are designed around realistic made-up users, so the product feels lived-in when people test it.
- Step 3
Build it clickable or coded
We build the agreed flows to the level the tests need, and you review them before anything goes in front of users or investors.
- Step 4
Hand over and plan the next step
You get the files and the boundary notes, plus our recommendation on whether the next move is more testing, a planning sprint or an MVP build.
Questions
Questions about Health app prototype
Why synthetic data instead of a few real users' records?
Real health information brings privacy and security obligations that a prototype has no reason to carry. Synthetic data is enough to test usability, align stakeholders and raise money without touching regulated territory. When your roadmap reaches real data, that becomes its own workstream with a specialist owner.
Clickable or coded: which one do I need?
Clickable is faster and covers most usability testing and investor demos. Coded makes sense when the test depends on real interaction, like typing an entry, running a timer, or data that changes as the user moves through the app.
Can I use the prototype in a fundraise?
Yes. Fundraising is one of the three jobs this package is built for, alongside usability testing and stakeholder alignment. Investors can tap through the product on their own device instead of picturing it from a slide.
Can the prototype turn into the MVP?
The design work carries straight into the build. Prototype code is written to answer questions quickly, so we mark which parts are worth keeping and which should be rebuilt for production. The MVP itself is scoped through a planning sprint first.
Is this only for healthcare and mental-health products?
No. Fitness, habit and wellness apps use the same approach. The synthetic-data boundary matters most for health and mental-health founders, which is why the package carries that name.
Should clinicians review the prototype?
If your product will sit anywhere near care, yes. Clinician and advisor feedback is one of the main reasons founders build a prototype. We prepare the flows for that review, and clinical judgment stays with your clinicians.
