Trackers | Chrt

chrt trackers are how you know where cargo is and what condition it’s in, independently of any other system. Use them when you need a verifiable record of where a shipment went and the conditions it travelled in — for medical shipments, high-value freight, international cargo, OBC hand-carry, or anything that needs cold-chain proof.

The three tracker types

Type	What it is	When to use it
chrt driver app	The driver’s iPhone or Android phone running the chrt app	Default tracker for any ground leg with a chrt driver. No hardware required.
Tive cellular trackers	Reusable Tags and single-use Labels that report GPS, temperature, light, and shock	Medical, cold-chain, high-value, or international freight. Hardware-level proof.
OBC mode	Either a driver phone or a Tive attached to an OBC’s bag, across a multi-leg shipment	Hand-carry shipments crossing flights and ground legs.

See Supported devices for the full matrix of what each device reports, who provides it, and where it shows up.

Two ways to use trackers

On a chrt order — attach trackers to cargo

When you build or manage an order in chrt, attach one or more trackers directly to cargo items. The tracker data appears on the order’s Map tab next to driver location, task progress, and proof-of-delivery — and on public tracking links you share with the shipper or end recipient.

Standalone — track without a chrt order

Register a device to your organization and start a tracking session for a specific shipment. Tracking sessions live independently of orders, which makes standalone trackers good for one-off shipments, customer-owned cargo, or cases where chrt is your tracking system but the order itself lives elsewhere.
