Quality & safety field tools
Prequis puts ISO 9001, API Q1 and API Q2 audit checklists and equipment inspections on the phone that's already in your pocket. It works with no signal, needs no account, and hands you a finished PDF before you're back at your desk.

ISO 9001:2015 · Clause 7.1.5.2
Measuring equipment in service carries a visible calibration status, and its records trace back to the equipment ID.
Grade the finding
The real control from the Audits module. Work it through.
One app, modular
Download Prequis for free and it opens on the module picker. Each module is a one-time purchase that unlocks its full checklist library — no subscription, no seat count, nothing to renew.
Module 01
Management-system audit checklists structured to follow the clause order of the standard you're auditing to.
$39.99–$59.99 per pack · $119.99 for all three
Module 02
Equipment and product inspections with a checkpoint runner built for one-handed use in the field.
$49.99 one-time
Next update
Five safety workflows, shipping in the next release. Near-miss and incident reporting will be free — nobody should be blocked from reporting a hazard.

The actual app
Not mockups — screens captured from the build that's on the App Store today.

What you leave with
One tap turns the job into a formatted PDF — header block, tallied results, every finding with its severity and objective evidence, and signature lines. Email it from site or hold it until you have signal. These are real exports, not mockups.
Not yet released
Five safety workflows are built and in testing: near-miss and incident reporting, a JSA/JHA builder with crew sign-off, toolbox talks with attendance, PPE and equipment checks, and behavior-based safety observation cards. None of it is purchasable yet — these are screens from the build in progress.
How a job runs
Pick the checklist, name the area or equipment, note who's auditing and when. Twenty seconds in the truck before you walk in.
Grade each item, add a photo where it matters, type the note while you're still standing in front of the thing. No signal needed — nothing is waiting on a server.
Tap once for a formatted PDF with your findings, severity grades and evidence photos already laid out. Email it from the site or hold it until you have bars.
Built for the field
Pricing
The app itself is free, and includes a demo audit so you can see the whole flow before spending anything.
Prices shown in USD. Purchases are handled by the App Store, so refunds follow Apple's policy. A module bought on iPhone won't carry over to Android when that version lands — the two stores bill separately.
What's next
Two things are coming: the Android build, now in review with Google Play, and the HSE module in the next update. Leave your email and you'll hear once for each — nothing else.
Two emails, total. No list rental, no newsletter.

Checklist content is written in original wording. Prequis does not reproduce the text, tables or acceptance criteria of any standard, and it is not a substitute for one — you still need your own licensed copy of any standard you work to, and clause references in the app are locators only.
Using Prequis does not by itself demonstrate conformity to any standard or satisfy any certification requirement.
