Halo HSE puts noise exposure calculations, risk assessments, field reports and chemical references — the daily tools of a working HSE professional — into one clean, fast iOS app. Built for the individual professional, not enterprise procurement.
Most safety software was built for enterprise procurement — nine-month rollouts, six-figure contracts, and a dashboard someone in head office looks at twice a year. The person actually doing the survey is left with a clipboard and a spreadsheet.
Halo HSE is the opposite. It's the tool you keep on your home screen because it's the fastest way to do a noise calculation, log the hazard you just walked past, look up a GHS pictogram, or check whether you've crossed the UAV threshold. One purchase, yours forever, works offline, syncs to your iPad through iCloud.
Enter measurements once. The app computes L_EX,8h against EU 2003/10/EC or OSHA 1910.95 (your choice), evaluates thresholds, and generates a professional PDF you can hand to a client — signed with your name, your role, your certification.
An observation, a near miss, something done well, an incident. Two lines and a photograph, filed under one of twelve hazard categories. Five name the directive that governs them; the rest cite the Framework Directive’s general duty, and the report says which it is. Link the measurement it is about and the PDF names the survey behind it. Location only when you ask, and never from a photo.
The 9 GHS pictograms with 22 representative H- and P-statements — not the full CLP Annex III list. The six EU directives you actually cite in reports, in plain language. Thirty pre-shift toolbox talks, ready to read aloud. Language pack: EN, LT, DE, PL.
Every noise survey, risk assessment and field report you complete is saved to your device and synced through your own iCloud — your Apple Account, not ours. Full change history on every record. No Halo servers, no Halo account, and nothing goes anywhere else unless you share the PDF.

The same LEX,8h calculation the app uses, running free in this browser. Add your exposure periods, see the result against the 80, 85 and 87 dB(A) values. No account, no sign-up, and nothing you type leaves your device.
08:30You're on-site. The client wants a noise survey done before the machines reach full pace. You open Halo HSE, tap New calculation, name it, and start entering readings from your sound level meter.
10:15Four periods logged with duration, SPL, and activity notes. The L_EX,8h reads 91.2 dB(A) — UAV reached. You tap Save, then Share, and export a signed PDF with your NEBOSH number in the surveyor block.
10:22The client has the report in their inbox before you're back at your van. Before you pull away you open Reports and log what you saw in Bay 4: two operators in the 91 dB(A) zone with no hearing protection. Two lines, a photograph, filed under PPE — 89/656/EEC — and linked to the survey you just saved, so the PDF names the number behind it. It stays on the open list until somebody closes it out.
That's the day. Your work, done in the tool made for it.
