Cross Check: Safety Checklist

The second person can't see what the first person checked. Both check independently, then compare — only the differing rows show up in red. A paper checklist's "sign-off" column gets signed while the previous person's checks are already visible, so the person confirming tends to miss the same things. It feels like a double check, but it's really just one person looking twice. DoubleCheck removes the first person's marks from the second person's screen by design, so that blind spot can't slip through. ▪ Hidden means it counts The second person only sees the item names. The first person's checks are never shown. Only after both finish can the results be compared. ▪ Only the differences turn red Matching rows stay as they are; only the differing rows turn red. Even with dozens of items, you can see at a glance where to look. ▪ Check again when needed If differences remain, both people can go through every item again. Repeat as many times as needed. ▪ Hand it off your way - Pass the same iPhone to the second person on the spot - Send it by QR to their own iPhone and check separately (no network needed) ▪ History and PDF Every check keeps a record of when, with whom, and how many differences. Share the history as a PDF anytime. ▪ No server, no account All data stays on your iPhone. No sign-up, no login. The only thing that passes between devices is a QR code. ▪ Run checks in parallel Run multiple checks on the same checklist at once — one per shipment, one per shift, and so on. Used for - Pre-shipment inspection: two people separately verify packing, quantity, and part numbers - Opening/closing checks: register count, locking up, and stock, checked independently - Equipment and vehicle pre-start checks: for items you can't afford to miss - Cleaning checks, handovers, and packing lists: two sets of eyes catch what one misses Eight ready-made checklists are included, and you can also write your own.
