SafetyCulture (now Mitti) vs Zentri for Lockout Tagout

SafetyCulture (now Mitti) vs Zentri is a choice between a checklist of the lockout and a live record of it. Mitti, formerly SafetyCulture and iAuditor, is a widely used inspection app that turns your lockout procedure into a configurable checklist. Zentri's Lockout Tagout module records the lockout as it happens, to your SOP, so you see who is under the lock without walking the floor and audit evidence is complete at close. Zentri is stronger on the live record.

• Choose Mitti if you want one proven app for inspections, training and asset checks on every topic, at every site.
• Choose Zentri if you want every lockout recorded as it happens, to your SOP, with nothing to chase at restart, handover or audit. Lockout Tagout is sold on its own, and Permit to Work can follow.

SafetyCulture (Mitti) vs Zentri at a glance

What is SafetyCulture (now Mitti)?

Mitti is the inspection and operations app of the Sydney-based company of the same name, called iAuditor until 2022 and SafetyCulture until its rename on 11 August 2026 (Mitti). More than 2 million people in 80,000 organisations use it, and it is rated 4.6 out of 5 on Capterra and G2. Lockout and permit to work are among its checklist types.

Where they differ

Your procedure, recorded live

Both build from your own procedure. Zentri also records each isolation point live. Mitti's builder is fast: it turns "paper checklists or Excel spreadsheets into smart inspection forms in minutes" (Mitti), with logic that can require a photo or a note. Zentri's lockout template mirrors your isolation sheet: its columns, who verifies first and second, and who approves before work and at close-out. Each point then shows its own status, signatures and scans, so the machine comes back with no sheet to chase.

Who is under the lock

Mitti records who took part. Zentri shows who is on the lock right now. Mitti's lockout checklist captures the employees involved, with photo and video evidence (Mitti). Its Construction module's gate sign-in records who is on site, not who is under a lock. In Zentri, everyone signs on to the lockout from their phone, and the register shows who is on, waiting or signed off. The supervisor sees everyone is clear before restart, and the second verifier can't sign until the first has.

Tests and shift changes

Mitti's checklist sets out the steps. Zentri tracks each test and handover live. Mitti's lockout template has a section for shift changes, and an inspection's owner can hand it to a colleague. Its public documentation doesn't describe lifting locks for a test mid-lockout, or re-checking points at handover. In Zentri, a test runs as a temporary removal session with a pre-check, only the points it needs, and a post-check. The crew tests without rebuilding the lockout, and the next shift inherits an isolation named verifiers re-walked and signed.

Proof at audit time

Mitti keeps a detailed edit history. Zentri adds a signed inspection record for each machine. On Premium and above, Mitti records every change to an inspection, with who made it, when, and the old and new answer (help). In Zentri, every machine carries its own inspection clock, so none is missed, and the reviewer signs off machine, date, employees and inspector, the four things OSHA asks for. When the auditor arrives, the evidence is an export, not a week pulling sheets.

When Mitti is the better fit

• Your main need is one inspection app for every topic, with templates your own teams build and change.
• Your inspections already work well in Mitti. Keep them, and add Zentri for the lockout, linked through Mitti's public API on paid plans.

When Zentri is the better fit

• You want one comprehensive lockout solution that actively tracks the work as it happens, from the first sign-on to close-out.
• Several people work under one lock and you need to see who, right now.
• You want evidence that holds up on the bad day: an OSHA inspection or an incident investigation.

Questions to ask Mitti in your demo

1. Can you configure this to our SOP, or do we change our SOP to fit your product?
2. Show a five-person lockout: who is signed on right now, and who verified each point?
3. How do we lift locks for a test without closing the lockout, and where is that recorded?
4. On a lockout that runs across shifts, how is each handover verified and recorded?
5. How does the app confirm the annual inspection was done by someone who didn't use the procedure?
6. On the plan we'd buy, how long is the activity log kept, and can we export it for an auditor?
