The Day Our Client’s App Went Down — And What Happened Next

How a single bug almost cost a startup $50,000—and how proactive app maintenance saved the day.

It was a Friday afternoon.
Our client, a fast-growing event ticketing startup, was preparing for their biggest online sale of the year.

Push notifications? Sent.
Ad campaigns? Live.
Traffic? Pouring in.

Then—nothing loaded.

The cause? A single outdated SDK that broke compatibility with the latest iOS update, which had rolled out just days earlier.Because their QA process was still running on last month’s OS version, the issue slipped through testing. By the time they contacted us, the app had been down for four hours—a critical window during a high-volume sales event.

Our AppFresh.io rapid-response team jumped into action:

• Identified the faulty SDK version causing API request failures
  
• Rolled back to the last stable release
  
• Patched the issue across both iOS and Android
  
• Monitored backend performance to ensure traffic recovery
  

Total downtime after our intervention? Under 90 minutes.
Projected revenue loss reduced from 100% to just 8%.

Mobile apps don’t usually crash because teams are careless—they crash because the mobile ecosystem moves faster than most teams can keep up:

Frequent OS updates (iOS, Android)

New device launches

Silent API deprecations

Dependency updates breaking backward compatibility

If you’re not actively monitoring, you’re reacting—and that reaction is expensive.

At AppFresh.io, we stop these disasters before they start. Our maintenance strategy includes:

• Weekly compatibility checks with beta and live OS versions
• Automated alerts for outdated SDKs and libraries
• Monthly proactive maintenance cycles
• 24/7 backend monitoring with instant alerts

This means bugs are fixed before users even notice.

Your app isn’t just lines of code—it’s your 24/7 storefront.

 If it’s down, even for an hour, you’re losing revenue, customer trust, and growth momentum.

The difference between a small hiccup and a business disaster?
Having a team that’s ready before the crisis hits.
