Your Mobile App Shouldn't Feel Slow

We started Thinksparkenergy because we kept seeing the same frustration from business owners. Their mobile apps worked, sure, but users complained about lag, battery drain, and crashes. Most developers just shrugged it off as normal. We knew better.

Let's Talk About Your App

The Real Cost of a Sluggish App

Last month, a retail client came to us after losing about 40% of their checkout completions. Their app took seven seconds to load the payment screen. Seven seconds doesn't sound like much until you remember people are standing in store aisles trying to use your app.

Their development team had built something functional. But functional and fast are different things. The app worked perfectly in testing environments but fell apart when 2,000 people hit it during a weekend sale.

We see this pattern constantly. Apps built without performance engineering from day one. Then businesses wonder why user reviews mention battery drain, why session times drop off, why people just use the website instead.

Performance isn't about making something pretty. It's about keeping your business operational when it matters most.

How We Actually Work With You

No two apps have identical problems. But our approach stays consistent because it actually works in real business conditions.

Real User Testing

We test your app the way your customers use it. During peak hours. On older devices. With spotty connections. The stuff that matters outside controlled environments.

Pinpoint the Bottlenecks

Most performance issues come from a handful of specific problems. Database queries that run wild. Images that haven't been compressed. Memory leaks that compound over time. We find them.

Fix Without Breaking

Performance changes can introduce new bugs if you're not careful. We implement improvements incrementally, test each change, and make sure your app stays stable throughout.

Why We Focus Only on Performance

Before starting Thinksparkenergy, I spent eight years at a mobile development agency. We built apps for everyone from startups to established retailers. And I watched the same cycle repeat: launch with excitement, then slow decline as performance issues accumulated.

Developers would promise to fix it later. But later never came because new features always took priority. Users adapted by simply using apps less.

So when we opened our doors in 2019, we made a specific choice. We don't build apps from scratch. We don't add features. We only do one thing: make existing mobile apps faster and more reliable.

It means turning down work sometimes. But it also means we've gotten really good at solving performance problems that other teams struggle with.

What Clients Say After Working With Us

These are actual people we've worked with. Real businesses here in Taiwan dealing with real app problems.

Branimir Novakovic

Operations Director, Retail Chain

We had been dealing with app crashes during sale events for almost a year. Every time we ran a promotion, our support team got flooded with complaints. Thinksparkenergy spent three weeks analyzing our setup and found the exact queries causing problems. Our last sale weekend had zero crashes. First time in fourteen months.

Lillian Osterkamp

Product Manager, Food Delivery Service

Our app reviews kept mentioning battery drain but our dev team couldn't figure out why. The team at Thinksparkenergy identified location tracking running constantly in the background even when the app was closed. After they fixed it, our App Store rating went from 3.2 to 4.4 in about six weeks. Just from solving that one issue.
