Security & Workforce

Mobile apps that work where signal doesn't.

We build and maintain mission-critical mobile apps for security workforce management. When your app goes down, guards can't work and revenue stops. We make sure that doesn't happen.

Why Security Companies Come to Us

Guard-facing mobile apps are uniquely demanding. They run 24/7, in harsh conditions, on varied devices, with unreliable connectivity.

The Challenges You're Facing

Security workforce apps fail differently than consumer apps. The consequences are immediate and financial:

  • Crash loops preventing guards from clocking in/out
  • Data sync failures losing incident reports
  • GPS drift causing missed geofence check-ins
  • Battery drain killing the app mid-shift
  • Poor offline behavior in basements and parkades
  • Android fragmentation on cheap employer-issued devices

How We Solve Them

We specialize in the exact problems that plague security mobile apps:

  • Crash diagnosis at the native layer, not just stack traces
  • Offline-first architecture with conflict-free sync
  • Aggressive battery optimization for 12-hour shifts
  • GPS accuracy tuning with fallback strategies
  • Tested on budget Android devices guards actually carry
  • Revenue-impact prioritization. We fix what hurts first

Case Study: Trackforce

How we resolved revenue-impacting mobile issues affecting thousands of security guards across North America.

Tracktik mobile application for security guards

Trackforce: Tracktik Mobile App

Trackforce is one of the largest physical security workforce management platforms in the world. Their Tracktik mobile app is used daily by thousands of guards for shift management, patrol tracking, incident reporting, and real-time communication with dispatch.

We were brought in to resolve critical, revenue-impacting stability issues. Guards couldn't complete shifts, incident reports were being lost, and crash rates were affecting client retention.

Our engineers embedded directly into the Trackforce engineering team. Same repo, same standups, same sprint cadence. We diagnosed root causes at the native layer, implemented fixes, and drove crash-free rates back up to production standards.

Security App Challenges We Solve

These are the problems that generic mobile developers struggle with, and that we've already conquered.

12-Hour Shift Endurance

Guards work long shifts and can't charge mid-patrol. We optimize background services, GPS polling frequency, and sync intervals to maximize battery life without sacrificing data accuracy.

Underground and No-Signal Zones

Parking garages, basements, and rural sites have no signal. Our offline-first architecture queues all actions locally and syncs transparently when connectivity returns.

Budget Device Compatibility

Guards often carry employer-issued budget Android phones. We test on low-RAM, older-OS devices and optimize memory usage, background process limits, and storage management.

Geofence Accuracy

Checkpoint verification requires accurate geofencing. We tune GPS provider selection, implement Wi-Fi/cell tower fallback, and handle GPS drift with intelligent smoothing.

Real-time Dispatch

Guards need instant push notifications for dispatch changes, emergency alerts, and shift reassignments. We implement reliable push delivery with acknowledgment tracking.

Compliance and Audit Trail

Security operations require tamper-proof logs. We implement GPS-stamped activity records, signed local event chains, and audit-ready data export for client reporting.

What a typical engagement looks like

Whether you need a new app built or an existing one stabilized, here is what each phase actually looks like. Built around remediation work because that is how most guarding clients reach us.

Day 1

Triage call with your engineering lead

We walk through crash reports, ANRs, support tickets, and your worst-performing devices. We rank issues by revenue impact, not technical glamour.

Week 1

Codebase audit and stabilization plan

We read the actual source. We document the architecture, identify the 3-5 changes that will move the needle, and tell you what we recommend leaving alone.

Weeks 2 to 6

Embedded in your team, shipping fixes

Same repo, same standups, same sprint cadence. Critical issues first, backlog after. Every fix tested against your guards' actual device mix, not a simulator.

Month 2 onward

Observability and prevention

Crash monitoring, performance baselines, on-call alerting. Issues caught before guards report them. Monthly written report on what we caught and what is trending.

When stable

Build forward, deliberately

New features only after the foundation is solid. Offline sync improvements, GPS accuracy, battery drain reductions. Continuous improvement at the pace your operations team can absorb.

Technical Capabilities

Deep mobile expertise tailored for the security workforce industry.

Native Android and iOS

Kotlin and Swift development with full access to platform-specific APIs for GPS, background services, push notifications, and device sensors.

Offline-first Architecture

Local-first data storage with CRDT-based conflict resolution. All operations work without connectivity and sync when back online.

GPS and Geofencing

Multi-provider location (GPS, Wi-Fi, cell), geofence management, patrol route tracking, and intelligent location sampling for battery efficiency.

Crash and Performance Engineering

Native crash analysis, ANR diagnosis, memory leak detection, startup optimization, and systematic regression prevention.

Background Services

Long-running background tasks that survive Android's aggressive battery restrictions. Foreground services, WorkManager chains, and OS-specific workarounds.

Push and Real-time Messaging

FCM/APNs integration with delivery guarantees, priority channels for emergency dispatch, and fallback polling for unreliable push environments.

Frequently Asked Questions

Can you work on our existing codebase?

Yes, that's how we typically engage. We join your repo, understand your architecture, and start contributing immediately. No rewrite required. We've worked in legacy codebases, modern Kotlin/Swift projects, and everything in between.

How quickly can you start?

Typically within 1-2 weeks. Our engineers are experienced at onboarding into existing teams quickly. We'll need repo access, crash reporting dashboards, and a point of contact on your engineering team.

Do you only do bug fixing, or also new features?

Both. We often start with stabilization (crash fixes, performance issues) and then transition into feature development once the app is healthy. Fix the foundation, then build on it.

What about React Native or Flutter apps?

We work with both, though for security workforce apps we typically recommend native for maximum control over GPS, background services, and device-specific behavior. If you have an existing cross-platform app, we can still help.

How do you prioritize what to fix first?

Revenue impact. We look at which issues are causing the most guard-hours lost, the most support tickets, and the most client complaints. We fix what costs you money first, then work down from there.

Can you help with App Store submissions and compliance?

Yes. We handle the full lifecycle including store submissions, review responses, and compliance requirements (background location justification, data privacy declarations, etc.).
