Your App Is Slow. Your Customers Are Leaving. Let’s Fix That

A slow app is a broken app in the eyes of your users. If your app is lagging, crashing, or just taking too long to load, your customers won’t wait. They’ll quit, delete, or leave bad reviews. App performance is no longer a nice-to-have, it’s essential to user retention and business success.

At Tappable, we believe app performance optimisation is a core part of app development strategy, not an afterthought. Slow apps don’t just annoy users; they hurt your business, cost you users, and damage your reputation.

If you want your app to thrive, you need to fix these issues now, before your customers do it for you. Here's how.

Speed matters more than you think

Your app’s performance is directly tied to how users perceive your brand. Even the most feature-rich app can lose users if it’s slow. We live in an era where users expect immediate gratification - every delay, no matter how small, could mean the difference between a happy user and a lost customer.

Think about it: how many times have you abandoned an app or website because it took too long to load? Users today are less forgiving. Research shows that over 50% of users will abandon an app if it takes more than 3 seconds to load. And, for every extra second’s delay, user satisfaction decreases significantly.

If your app isn’t performing optimally, you risk alienating users, losing conversion opportunities, and getting poor reviews.

Common causes of slow apps

So, what causes your app to be slow? There are many factors at play, but the most common performance issues are tied to:

• Bloated or unoptimised code: Poorly written code can create unnecessary delays, causing your app to slow down.

• Inefficient APIs: Slow or poorly structured APIs make it harder for your app to fetch data quickly.

• Uncompressed or oversized media: Large images, videos, or graphics can severely slow down load times if they aren’t optimised.

• Outdated libraries or dependencies: Legacy code can introduce bottlenecks that slow app performance.

• Lack of caching or lazy loading: Not caching data or using lazy loading techniques can make your app feel sluggish.

At Tappable, we conduct thorough performance audits to identify and eliminate these bottlenecks before they become major problems.

Our approach to performance optimisation

Performance is baked into every stage of the development process, not something we add on later.

For existing slow apps, we start by conducting a detailed performance audit. This audit looks at everything that could be slowing down your app, including:

• Launch times

• Screen transitions

• Network efficiency

• Backend or frontend bottlenecks

Once we’ve assessed the performance, we prioritise fixes based on real-world impact. We don’t just focus on theoretical improvements, we focus on what will make the biggest difference for users, ensuring a smoother, faster experience.

For new apps, we ensure speed optimisation is built in from the start, helping to avoid future bottlenecks and ensuring the app performs well at scale.

Why app performance matters and how it impacts your business

Slow apps drive users away, hurt your ratings, and ultimately cost your business. Poor performance impacts user retention, conversion rates, and revenue. In 2025, users expect fast, smooth, and reliable apps. A laggy experience can lead to negative reviews, low ratings, and a damaged reputation in app stores.

Performance isn’t just about fixing bugs later, it needs to be baked into your app’s strategy. Apps that are quick and responsive see better user loyalty, higher retention, and more positive feedback, which leads to higher rankings and greater success.

Optimising performance for better user retention

Improving app performance isn’t a one-time task, it’s about consistent improvement. Whether it’s fixing slow loading times, optimising code, or refining backend processes, every step matters. The key is to identify and address bottlenecks that directly impact the user experience.

By optimising your app’s performance from the start, you ensure long-term user satisfaction and business growth. A fast, well-optimised app delivers a better experience, drives higher ratings, and keeps users engaged.
