Healthy Homes
The Healthy Homes assessment app for New Zealand
HammerHand turns a voice-and-photo walk-through into a complete Healthy Homes assessment — all five standards, numeric pass/fail, and the heating and insulation maths done for you — signed off the same day, and it all works offline.
Five standards
Every Healthy Homes standard, assessed properly
Heating, insulation, ventilation, moisture ingress and drainage, and draught stopping — each captured against the standard with a clear numeric pass or fail, rolled up into one compliance verdict you can hand a landlord or property manager.
- Numeric pass/fail against all five standards
- One clear overall compliance verdict
- Photos and notes attached to every standard
Built-in helpers
The heating and insulation maths, done for you
No spreadsheets on the tailgate. HammerHand includes a heating-capacity helper and an insulation R-value helper, so the required heating output and the insulation position are calculated deterministically — not estimated.
- Heating-capacity calculation built in
- Insulation R-value helper
- Deterministic result, not guesswork
Offline & defensible
Works in the subfloor, stands up later
Capture works with no signal and syncs when you’re back in range. Every finding is time- and location-stamped, the AI-drafted note is confirmed by you, and the published report is a locked snapshot — the record you need if a report is ever questioned.
- Fully offline capture
- Time- and location-stamped evidence
- AI drafts, you verify; immutable report
