Mobile Application Deployment Checklist

Sit down with dispatch leads and the safety director to confirm what ships in v1.0: HOS clock visibility, DVIR submission, dispatch messaging, document capture (BOL/POD photos), and accessorial logging. Capture sign-off so feature creep does not slip the launch — anything not signed off here ships in v1.1.

If the app records driving hours, the underlying ELD must appear on the FMCSA Registered ELDs list and meet 49 CFR 395.20 technical specs. Pull the registration ID, the supported tractor ECMs, and the malfunction-handling behavior so audits and roadside inspections have ready answers.

Cover the actual devices in driver hands — newest iPhone, two-year-old Samsung, the rugged tablets in sleeper-cab mounts. Run a full pre-trip DVIR, an HOS duty-status change, a BOL photo capture, and a dispatch message round-trip on each device. Note any OS versions that fail.

Force TLS 1.3 on the API gateway and reject anything older. HOS, MVR data, and driver PII flow through this pipe — TLS 1.0/1.1 endpoints showing up in a pen test become an audit finding fast.

Scope the test to the mobile binary, the backend API, and the authentication flow. A reputable firm produces a written report with CVSS-scored findings; allow at least two weeks between report delivery and launch so critical findings can be remediated and retested.

Categorize every finding by CVSS severity. Critical and High block launch; Medium and Low can ship with a tracked remediation ticket. Document the decision and rationale per finding — security audits will ask.

Fix the issue, ship a patched build to the pen-test firm, and obtain a written retest letter clearing each Critical/High item. Do not launch without the retest letter on file — insurance and shipper security questionnaires will request it.

Spell out what the app collects (location, HOS, vehicle telematics, photos), who sees it (dispatch, safety, the carrier, FMCSA on request), and how long it is retained. Drivers in CA/CO/CT need CCPA/CPA disclosures; collective-bargaining drivers may have union-side requirements.

Drivers operate the app from a windshield mount with one hand, often wearing gloves. Tap targets need to be large, the duty-status switch needs to be reachable with a thumb, and any modal that locks the screen while moving must comply with the ELD driver-distraction rules in Part 395.

Contrast ratios for sunlight readability, VoiceOver and TalkBack labels on every actionable control, dynamic-type support up to 200%. Older drivers and drivers with corrective lenses are a meaningful share of the user base.

Pick a mix — long-haul OTR, regional, and local P&D — so the app sees real coverage gaps, real dock-door waits, and real load/unload flows. Collect a structured feedback form plus the raw call notes from the driver manager. Look for the patterns, not the one-off complaints.

Keep it under eight minutes. Cover login, the pre-trip DVIR flow, duty-status changes, dispatch messaging, BOL/POD photo capture, and how to log a malfunction. Drivers will watch this on a phone in a sleeper berth — assume that environment.

Dispatchers and the safety team are the front line when drivers call in with app problems. Walk through the top eight expected issues — login failure, ELD sync error, GPS drift, photo upload stall, dispatch message lost, duty-status edit, malfunction code, password reset — and the named owner for each.

Push the announcement through the driver app, settlement statement insert, and dispatch radio brief. Include the go-live date, the support number, and a link to the video walkthrough. Drivers who do not check email regularly will see the radio and the paper insert.

Sentry or Crashlytics on the binary, Mixpanel or Amplitude on the event stream. Tag releases so you can compare crash-free session rates across versions during the rollout. Alert on any single error class exceeding 1% of sessions.

Drivers will not open a Zendesk ticket; they will call dispatch. Wire the in-app help button to a phone number staffed during dispatch hours, with after-hours routing to the on-call dispatcher. Track first-contact resolution and recurring issues weekly.

Drivers update apps slowly; a predictable cadence trains them. Bi-weekly patches for bug fixes, monthly for minor features, quarterly for major releases. Coordinate with App Store and Play Store review windows — Apple commonly takes 1-3 days.

Pick a launch day that is not a Friday and not the day before a holiday. Have the safety director, lead dispatcher, and shop manager on standby for two hours after the App Store push goes live. Hold the legacy logging app in place as a rollback option.

Pull the crash-free session rate daily from Sentry or Crashlytics. Anything below 99.5% on Android or 99.7% on iOS by day three is a signal to investigate root cause and consider rollback. HOS-recording crashes are especially serious — driving time may be lost.

Stage the prior-version binary in the App Store and Play Store, push a forced-update prompt to active driver devices, and notify dispatch to expect calls. Preserve the crashed-version logs and Sentry events for the post-mortem.

Two weeks in is the sweet spot — drivers have used the app on real loads but the experience is still fresh. Combine a short in-app survey with five structured phone interviews from driver managers. Roll the themes into the v1.1 prioritization meeting.
