We Keep Your Apps Running Smoothly
Building mobile apps is just the beginning. What happens after launch? That's where most teams struggle. We handle updates, fixes, and technical support so your app stays current and your users stay happy.
Based in Cheongju, we've spent years working with businesses that need consistent, reliable mobile app maintenance. No drama. Just steady technical work that keeps things working.
What We Actually Do
Our team focuses on practical mobile app support that solves real problems for businesses operating in the Korean market.
Update Management
OS updates come out constantly. We test your app against new Android and iOS versions before they cause problems for your users. Regular compatibility checks prevent those embarrassing crashes.
Bug Resolution
Users report issues. We track them down, fix them, and get updates deployed. Average response time for critical bugs is under four hours because waiting around costs you customers.
Performance Monitoring
We watch how your app performs in the real world. Load times, crash rates, memory usage—all the technical stuff that affects whether people keep using your app or delete it.
Security Patches
New vulnerabilities get discovered regularly. We apply security updates and keep your app protected against current threats. This matters more than most businesses realize until something goes wrong.
Feature Updates
Need to add functionality? We handle the development, testing, and deployment. Small improvements or major additions—whatever makes sense for your business goals.
User Support Integration
When your support team gets technical questions, we help them answer quickly. We also analyze user feedback to spot patterns that indicate deeper technical issues.
Sanna Virkkala
Senior Technical LeadI started working with mobile apps back in 2014 when everything was simpler. Fewer devices, fewer OS versions, fewer complications. Over the years I've seen how maintenance became its own specialty.
Most developers want to build new things. I found I actually enjoy the puzzle of keeping existing apps healthy. There's satisfaction in diagnosing a weird crash that only happens on specific Samsung models running Android 13. Or figuring out why an app drains battery on some devices but not others.
At HubPortalConnect, I work with a small team that shares this mindset. We're the people who care about the unglamorous technical work that keeps apps functioning properly day after day.
How We Work With Clients
Most companies contact us after they've already launched an app and realized maintenance takes more time than expected. Their developers moved on to other projects. Updates pile up. Users complain.
We step in and take over the technical care. You get monthly reports showing what we did, what issues came up, and what we're monitoring. Everything stays documented so you're never wondering what's happening with your app.
We work on retainer because app maintenance isn't project-based—it's ongoing. Predictable costs, consistent availability, and direct access to people who know your codebase inside out.
Our Operating Principles
Fast Response Times Matter
When something breaks in production, four hours feels like forever. We maintain quick response times because we know your users won't wait around while you figure things out.
Prevention Beats Firefighting
Regular maintenance catches problems before users do. We'd rather spend time preventing issues than scrambling to fix emergencies. Both cost money, but prevention causes less stress.
Clear Communication Always
Technical jargon helps nobody. We explain issues in plain language and present options with honest assessments of effort and risk. You make informed decisions, we handle the implementation.
Documentation Is Non-Negotiable
Every change gets documented. Every bug gets tracked. Every decision gets recorded. This protects both of us and makes future work more efficient. No one should have to reverse-engineer their own app.
