Your chain-of-custody form,
filled out by talking.

Record a walkthrough on your phone and just talk — “Sample 5, popcorn ceiling, north corner.” SampleChain fills your lab’s chain-of-custody form, row by row, and keeps the count straight. No clipboard, no handwriting.

Free while in early access. Works on iPhone and Android.

From job site to lab in one take

Step 1

Record the walkthrough

Start a video on your phone and point at each bag as you collect it. The clip saves to your camera roll so you never lose a job.

Step 2

Just talk

Call out each sample as you go — number, material, location. SampleChain listens and reads the bag numbers off the video.

Step 3

Get the filled form

Your lab's chain-of-custody form comes back filled in, row by row, with the count checked and ready to send.

Stop writing chain-of-custody by hand

Set up your company once, then turn every walkthrough into a finished form. Free while we get it dialed in with the first crews.
