Report in a minute
Incidents and near misses from the phone, with photos. No signal? The report is kept on the phone and sent when the connection is back.

Most safety problems are seen first by the people on site, and most are never written down: the form is in the office, the app needs a signal, the report goes nowhere. Custos is built the other way round. A worker reports from the phone in a minute, on a building site with no signal, and the report reaches the person who must act on it. Every finding then becomes a job with an owner, a due date and a second person who checks it was really done.
Report in a minute
Incidents and near misses from the phone, with photos. No signal? The report is kept on the phone and sent when the connection is back.
Nothing is forgotten
Investigations, root causes and corrective actions with owners, due dates and verification. An incident cannot close while a fix is still open.
Routine checks without paper
Your own forms and checklists, given to the right people at the right site, filled in offline. A failed item can start a corrective action at once.
Rules people have read
Procedures and site rules as PDFs, given to roles or named people, acknowledged per version. When the rules change, people are asked again.
Records for the regulator
Which injuries must be recorded, and by when the authority must be told. In the United States, the OSHA 300 log, Form 301 and the 300A summary are filled in for you.
See how you are doing
A dashboard of what waits for you and how the company is doing, and injury rates (TRIR, LTIR, DART) from the hours worked.
Companies of 50 to 500 people that take safety seriously but have no team of specialists to run a large system: construction, manufacturing, logistics, facilities. There is nothing to install: add your sites and invite your people, and they can start reporting.
| Role | What Custos does for them |
|---|---|
| Workers | Report what they see, do the jobs they are given, fill in checks, confirm they read the rules |
| Supervisors | Make sure every report is looked at, name investigators, give and check the fixes |
| Safety managers | Decide what must be recorded and reported, keep the records, see whether things improve |
| Visitors and contractors | Read and acknowledge the site rules before they start, and nothing else |
