Monthly checks slip
Paper checklists live in binders, drawers, or taped to cabinets. If the responsible person leaves, the process often leaves with them.
Validation prototype for small organizations with AEDs
Replace the AED paper checklist with a QR code and reminders.
DefibLedger helps small organizations track AED readiness tasks, monthly inspection records, and pad/battery expiration dates without turning it into a heavy compliance program.
DefibLedger helps organize AED readiness records and reminders. It does not provide medical or legal advice and does not guarantee compliance with state, local, or organizational AED requirements.

Scan cabinet QR → complete 60-second check
No app install for volunteers, trainers, office managers, or facilities staff.
The orphan workflow
AED ownership usually starts organized. Then the log sheet gets forgotten.
Most small organizations do not need an enterprise safety platform. They need a simple way to know the AED was checked, the cabinet is accessible, and supplies are not quietly expiring.
2
Dates expire silently
Pad and battery dates are easy to miss until someone opens the cabinet, asks for records, or notices an old label.
3
Records are scattered
Admins need clean inspection records for board, insurance, inspection, or internal safety review — not a half-filled sheet.
How it works
Built around the cabinet, not another app to manage.
The checker scans the AED’s QR code, answers a short readiness checklist, and the admin gets organized records plus upcoming expiration reminders.
Add the AED
Record location, model, serial number, battery date, adult pad date, and optional pediatric pad date.
Print the QR
Place a QR label on the AED cabinet so any approved staff member or volunteer can start the monthly check.
Keep records clean
DefibLedger stores inspection history, flags overdue checks, and creates exportable logs.
Best first-fit organizations
This prototype is intentionally small-org first — designed for one to ten AEDs, not fleet-wide enterprise safety operations.

Clickable prototype
Scan a QR. Complete a monthly readiness check. Leave a record.
This is the validation demo: enough for a church admin, gym owner, dental office manager, or CPR/AED trainer to react to the workflow before building a full SaaS.

Sample export
Clean records when someone asks, “Are we checking these?”
DefibLedger’s export is intentionally plain: what was checked, when, by whom, and what needs attention. No legal guarantee. No fake certification. Just organized records.

Validation next
We only build the full product if real AED owners confirm the pain.
The next milestone is not “ship SaaS.” It is 10 conversations, 3 current log examples, 2 pilot commitments, and 1 paid pre-order or LOI at $49–$99/year per AED.
Questions this demo should answer:
- Would this replace your paper AED log?
- Would QR-code checks work for your staff or volunteers?
- Would expiration reminders solve a real recurring risk?
- Would clean exports help with board, insurance, or internal review?
- Would you pilot this with one AED?
