## What is Halo HSE?

Halo HSE puts the calculations, references, and reports of a working Health, Safety and Environment professional into one clean iOS app. Built for the individual on-site — not enterprise procurement.

FOUR CALCULATORS

• Noise TWA — 8-hour daily exposure (L_EX,8h) against EU 2003/10/EC or OSHA 1910.95. Multi-period, evaluated LAV / UAV / ELV thresholds.
• Hand-arm vibration — A(8) daily dose per EU 2002/44/EC. Multi-tool magnitudes and durations, HSE exposure points.
• NIOSH lifting equation — full 1991 Revised Lifting Equation with all six multipliers (HM, VM, DM, AM, FM, CM), RWL and Lifting Index.
• Risk matrix — configurable 3×3, 4×4, or 5×5. Save custom hazards per site.
• Confined space gas — coming soon.

FIELD REPORTS

• Log what you saw — observation, positive observation, near miss, or incident.
• Photographs from the camera or your library, compressed on import. Location only if you ask for it, and never from a photo: GPS is stripped from every image.
• Twelve hazard categories, each citing the EU instrument that governs it — and saying so plainly when the citation is the Framework Directive's general duty rather than a specific rule.
• Link the measurement the report is about, so the PDF names the survey behind it.
• An open-items worklist, so you can see what is still outstanding at a glance.
• Free. Capture is the part you do every day.

THREE REFERENCE MODULES

• GHS — the nine pictograms with 22 representative H- and P-statements, searchable. Not the full CLP Annex III list.
• EU directive quick-reference — 2003/10/EC, 2002/44/EC, 89/391/EEC, 89/656/EEC, 90/269/EEC, 92/58/EEC in plain language.
• 30 toolbox talks — pre-shift briefings, ready to read aloud.

BUILT FOR THE FIELD

• Works fully offline — every calculator, every reference, every saved record.
• iCloud sync across your devices (optional).
• PDF export signed with your name, role, and certification.
• Change history on every record.
• Available in English, Lithuanian, Polish, and German.
• No accounts, no servers — your data stays on your device.

## Version history (last 4 releases)

### 1.2.0 — 2026-10-13

The reference content now reads in your language.

All 30 toolbox talks, the six EU directive summaries, the nine GHS pictogram descriptions and the 22 representative H- and P-statements follow the language your iPhone is set to — English, German, Lithuanian or Polish. So do the row labels on exported PDFs, and the tab bar.

For the H- and P-statements the wording is the official text of Annexes III and IV to Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures, taken in each language rather than translated from the English. Those phrases are prescribed by law, so a statement you copy out of Halo HSE is the one that belongs in the document. The set is still 22 representative statements, not the full Annex III and Annex IV lists.

Confined space gas is still to come.

### 1.1.0 — 2026-10-07

Field reports. Log what you saw — an observation, a near miss, something done well, or an incident — with photographs, the EU instrument that governs the hazard, and an optional link to the measurement it is about, so the exported PDF names the survey behind it.

Saved is now one archive for everything, calculations and reports together. The Reports tab shows only what is still open.

Pro adds CSV export of your register, one row per report.

Also in this version:

• Corrects the citation printed on NIOSH exports. The revised lifting equation is 1991; publication 94-110 (1994) is the applications manual, not the equation itself.
• Clearer, more accurate copy on the home screen, in all four languages.
• iCloud sync now works as it should. The container schema was incomplete, which is why records were not appearing on a second device — nothing was lost, and existing records sync on next launch.

### 1.0.1 — 2026-08-30

Halo HSE Pro is now available to purchase.

### 1.0 — 2026-08-27
