An iOS-compatible ELD is an exact registered hardware/software system, not merely an app in the App Store. Verify the current iOS version, device model, cable/vehicle fit, permissions, offline recovery, and roadside transfer with the provider and in a real vehicle before rollout.
Completed iOS pilot scorecard
| Scenario | Result to record | Release rule |
|---|---|---|
| Screen lock/background | Events and reconnect behavior through controlled use | No missing/duplicate required events |
| Low-power and permission change | Warning, failure mode, driver recovery | Driver can identify and recover under policy |
| Vehicle swap | Correct VIN/device/cable assignment | No cross-vehicle event contamination |
| Offline/reconnect | Sequence before, during, after loss | Complete reconciled record |
| Roadside | Supported transfer/display on pilot version | Second person reproduces the result |
What to check
| Check | How to verify |
|---|---|
| 1. Inventory the fleet's Apple devices and operating versions | Keep each iPhone or iPad model, OS build, owner, vehicle assignment, charging method, update policy, and replacement plan. |
| 2. Match the exact ELD registry and current provider support | Retain official-list device/hardware/software/ID/status plus dated provider support for each Apple model and OS tested. |
| 3. Run permission background lock and power tests | Record permissions and observed app/ELD behavior after screen lock, backgrounding, low-power mode, call interruption, restart, and update. |
| 4. Run a controlled offline recovery test | Save disconnection and reconnection times, queued events, recovered order, duplicate or missing-event review, user action, defect, and retest. |
| 5. Score every critical task across representative vehicles | Keep a vehicle-by-device matrix for login, engine data, statuses, edits, certification, offline recovery, transfer, critical failures, owner, and decision. |
