## SampleChain Description
SampleChain is an offline chain-of-custody worksheet for environmental and industrial-hygiene field work.

COC FORMS IN THE FIELD
- Create a COC with client, site, laboratory, sampler and cooler details
- Add sample rows fast: sample ID, matrix, location, collection time, containers, preservation and requested analysis
- Free for 3 COC records (10 samples each) - every feature included

CUSTODY THAT HOLDS UP
- Relinquished, Received and Shipped events with names, initials and times - entered by you
- Saved events are never overwritten: corrections are appended as their own entries, so your sequence stays intact

REUSE WHAT YOU TYPE
- Lab presets and organization defaults fill repeated fields automatically

LAB-READY OUTPUT
- COC PDF with the full sample table and custody sequence
- CSV export of samples for your project files

PRIVATE BY DESIGN
- 100% offline. No account, no cloud, no analytics

PRICING
Free for up to 3 COC records with 10 samples each; existing records stay viewable and exportable forever. Pro (unlimited COCs and samples) is an auto-renewing subscription - $19.99/month or $149.99/year - with a 7-day free trial. It renews unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in Settings > Apple ID > Subscriptions.

For record-keeping only. Entries are user-reported and not identity-verified.
