99.5% Crash-free Target

24h Critical Response

10+ Apps Maintained

Same Day OS Update Testing

Engineering experience across

Production maintenance scope

Mobile applications require planned work as operating systems, devices, dependencies, policies, and production usage change.

Risks of deferred maintenance

Mobile apps have a unique fragility: they run on hardware and OS versions you don't control.

iOS/Android updates break existing functionality
Crash rates climb as new devices enter the market
Third-party SDKs deprecate and stop working
App Store policy changes require code updates
Performance degrades as data volume grows
Security vulnerabilities emerge in dependencies

Active maintenance controls

A planned maintenance program can include:

Same-day testing when new OS betas drop
Proactive crash monitoring with root-cause analysis
Dependency updates on a regular cadence
App Store policy tracking and required implementation work
Performance profiling and optimization each quarter
Critical security advisories triaged within 48 hours

Tracktik mobile application by Trackforce

Case study · Trackforce

Tracktik: maintaining a 10-year-old security workforce app

Trackforce runs Tracktik, one of the largest mobile platforms in physical security. Used daily by thousands of guards across North America for shift management, patrol tracking, and incident reporting. The codebase is 10 years old.

The scope covered ongoing stability for an application already in production: native investigation of revenue-impacting crashes, OS compatibility work, and dependency management in a long-lived codebase.

Following the stabilization work, the application returned to its crash-free session target and continued on a regular release cadence.

“…for the work you've done resolving revenue-impacting issues from the Tracktik mobile app.”

Sorin Voicu VP Engineering, Trackforce

Case study · CLEIO

Continuous mobile work for CLEIO's EEG Android app

CLEIO is a Quebec neurotechnology company building EEG headset companion apps. Their Android codebase needed senior capacity for ongoing development and maintenance work: feature delivery, stability through Android version transitions, dependency upkeep, sprint-by-sprint releases.

CLEIO engaged DEVSFLOW for ongoing Android engineering across multiple project cycles. The work covered feature delivery, OS transitions, dependency upkeep, and the release rhythm a hardware-connected app needs in production.

The work followed CLEIO's existing sprint, review, and release process.

“…a dependable, communicative, and professional consultant…integrated smoothly into the project team, ramped up on the project context efficiently, and consistently delivered against the cadence set by the client.”

Gabriel Director of Software Development, CLEIO

What's included

A defined set of recurring controls and engineering activities for production applications.

OS compatibility

We test supported application workflows against relevant iOS and Android beta releases, document compatibility findings, and schedule required changes before public release where timelines permit.

Crash monitoring and resolution

Continuous crash monitoring with automated alerting. When crash-free rate drops below threshold, we investigate, diagnose, and ship a fix, often before users report it.

Performance optimization

Quarterly performance audits covering startup time, memory usage, battery impact, and network efficiency. We identify regressions and optimize proactively.

Dependency management

Regular updates to third-party SDKs, libraries, and toolchains. We test each update in isolation, catch breaking changes, and keep your app off deprecated APIs.

Security patching

We monitor dependency advisories and triage critical findings within 48 hours. Remediation timing is based on exploitability, application exposure, vendor availability, regression risk, and release controls.

App Store compliance

Apple and Google change policies regularly. We track policy updates, assess impact on your app, and make required changes before your app gets flagged or removed.

Bug fixes and minor improvements

A monthly allocation of development hours for bug fixes, small UI improvements, and minor feature tweaks. Keeps the app moving forward without a full engagement.

Monthly reporting

Clear monthly reports covering crash rates, performance metrics, completed work, upcoming risks (OS releases, SDK deprecations), and recommended actions.

Standard maintenance plan

The standard plan covers the recurring controls used across many production applications. Scope and service levels are adjusted when the application's risk profile or release obligations require it.

Recommended for most apps

Professional Maintenance

Active monitoring, OS readiness, and the development hours you need each month.

For production applications that require active monitoring, scheduled maintenance, and a defined response process for critical issues.

Continuous crash monitoring with alerts
OS beta testing the day each new beta drops
Monthly dependency and SDK updates
Quarterly performance profiling
App Store policy compliance tracking
24-hour critical issue response
15 hours per month for bug fixes and small features
Monthly written report with risks and recommendations

If this isn't quite right for your app

Lighter coverage

For stable apps with low traffic (MVPs, internal tools, occasional users). Drop OS beta testing, weekly response windows, and the full development allocation. Email us with the use case.

Dedicated engineer

For mission-critical apps in fintech, healthcare, or workforce management where downtime is revenue. Same plan, plus a named engineer on weekly syncs and faster escalation. Email us with the situation.

Not sure which fits? Tell us about your app and we'll recommend the right one, or build a custom plan if none of these match.

Frequently asked questions

We didn't build our app with you. Can you still maintain it?

Yes. Most of the apps we maintain were built by other teams. We'll do a thorough codebase audit during onboarding to understand the architecture, identify risks, and get up to speed quickly.

What happens when a new iOS or Android version drops?

We test supported workflows against relevant beta releases, document compatibility findings, and schedule required changes against the public release date. Coverage and timing depend on the supported OS matrix and the severity of any platform change.

How do you handle critical production issues?

The Professional Maintenance plan includes a 24-hour initial response target for critical issues such as crash spikes, data loss, and security vulnerabilities. Triage establishes severity, containment, remediation, validation, and release steps; resolution time depends on the cause and required controls.

Can maintenance hours roll over month to month?

Yes, unused development hours roll over for up to 2 months. This gives you flexibility for months where more work is needed without losing hours in quieter months.

What if we need more development hours than our plan includes?

Additional hours can be purchased at any time. If your needs consistently exceed the standard allocation, we'll discuss either a Dedicated Engineer arrangement or a custom plan since that's usually more cost-effective.

Do you handle App Store submissions?

Yes. We manage the full release cycle including build preparation, App Store Connect/Play Console configuration, review submission, and handling any review rejections or compliance requests.

What's the minimum contract length?

Our minimum contract is 3 months to cover onboarding and codebase audit. After that, it's month-to-month with 2 weeks notice. We typically see the best results after 6 months, but there's no long-term lock-in required.
