Which iOS Performance Testing Tools should be used in 2025?

Performance Testing in general, can be quite challenging and especially for iOS since it inherently has many complex and hidden steps that need to be taken to achieve data transparency.
When choosing a tool for iOS performance testing, multiple features must be considered, such as the tool's features, user-friendliness, integration with other products, and price.

Challenges in iOS Performance Testing

As in any testing environment, iOS performance testing also has problems and challenges. The latest ones for this year are:

1. Complexity of the iOS devices: iOS devices differ in a range of hardware and software setup hence accessing data and key metrics could be challenging across this big ecosystem
2. iOS versions change fast and big: Apple is very eager to upgrade their software and release new versions of iOS, which again brings in new challenges to performance
3. Increasingly complex iOS apps: More complex iOS application are difficult to test regarding their performance as they introduce more features and dependencies
4. Limited device availability: Sometimes, accessing all iOS devices to test an application may be challenging. The financial cost also comes into play for newer devices.

Let’s look at the best iOS performance testing tools out there.

Selecting the right iOS Performance Testing Tools

The choice of iOS performance testing tools in 2025 would be based on your particular needs and priorities. Here are some aspects for you to consider:

• Features: What exactly would you want to measure in terms of performance? Do you want to perform tests on network performance, CPU usage, memory consumption, or battery life?
• Ease of use: How easily can the tool be learned and used?
• How user-friendly does the interface make it?
• Integration: How does the tool fit into your current development and testing workflows?
• Price: How much does it cost? Is the tool-free, a subscription-based fee, or a freemium arrangement?

After carefully considering the parameters mentioned above, I use BrowserStack for performance testing and automation testing with already-made integrations for Appium and Xcode.
With all the possible apps from BrowserStack, such as App Live, App Automate, and App Performance, your projects are covered in any testing you might encounter!
