Proven where mistakes cost the most.
Aviation, surgery, intensive care — where a missed step costs a life, the fix wasn’t more talent or more software. It was a checklist.
The Army's new bomber crashed on its demonstration flight — one control left locked. The verdict: not too much airplane to fly, too much to remember. The fix was the first pre-flight checklist; the next twelve aircraft flew 1.8 million miles without an accident.
Wright Field — the Boeing Model 299
More than a hundred Michigan ICUs adopted a five-step checklist for placing central lines. The median infection rate fell from 2.7 per 1,000 catheter-days to zero within three months — and stayed down.
NEJM — the Keystone ICU project
Eight hospitals around the world ran a 19-item surgical checklist. Major complications fell by more than a third. Deaths fell by nearly half.

Your room doesn’t have to be an operating room.
The discipline carries anywhere work repeats and a skipped step costs money, trust, or safety. Find your trade — each of these is the checklist a lead would write, killer item and all.

A five-star listing dies by small misses — a stale door code, a stripped bed nobody remade, an empty coffee tin. The turnover is the product.
Turnover clean
Template- Strip beds, start the wash
- Check under beds and sofa cushions
- Restock coffee, paper, soap
- Reset the door code for the next guest
- Photograph every room as staged
- Lock the owner's closet
Write it once. Your team runs it, by name.
A checklist in a team space runs on a schedule you set: the run is created on time, steps carry the names you assigned, and what’s unfinished is visible without anyone chasing it down the hall.
The new keyholder closes the store the way the owner would — first night, no shadowing — because the list, not the veteran, carries the knowledge.

And the record answers for you.
When someone asks how you know it gets done — a manager, an auditor, a client on a renewal call — you don’t say “trust us.” You open the record: every run, every check, who and when, with corrections appended rather than painted over.
It cuts both ways, and that’s the point. A skipped step shows as skipped; a late run shows late. A record that only flattered you would be worthless in the room where you need it.

One space for the team.
A team space holds the templates, the schedules, and the record. Invite up to 25 people by email — Checkl sends the invitation — and each person’s assignments land in their own Today, next to whatever else their day holds.
Team is priced per member: $12 a month each, or $120 a year. SAML SSO is an add-on at exactly our cost — $125 a month, no markup — and Enterprise starts at $2,400 a year. If billing ever lapses, the space goes read-only, not dark: the record stays readable. The trial carries the risk — 14 days free, and a 30-day money-back guarantee after that.
