What we build

We build small, focused apps that respect the people using them. That means: no account where none is needed, no cloud copy of personal data by default, and no advertising or third-party tracking built into our products.

Our first product is BP Folio, a manual blood-pressure log for iPhone. The phone cannot measure blood pressure; BP Folio only records numbers you enter by hand, and it does not diagnose or give medication advice. See the home page for more on BP Folio.

How to reach us

We do not run a contact form and we do not collect messages through this site. Email is the right way to reach us: support@haoduoniutech.com. For privacy questions about BP Folio, the same address reaches the team that handles them.
