To ensure that AlignKit delivers optimal performance and robustness, we conducted various forms of performance testing. Below is a detailed overview of the key tests we performed, along with their results.
Note
The following simulation was done on iPhone 14, running on iOS 18.1 with a testing procedure of same parameters
A consistent and smooth user experience requires the OS to maintain a refresh rate of 60 FPS. Any significant drops in FPS can lead to visual stuttering and poor performance perception. With AlignKit, we consistently achieved stable FPS, ensuring smooth animations and seamless UI interactions.

The time required to initialize and apply constraints directly impacts the app's launch performance. With AlignKit, we observed a significant improvement in constraint setup performance compared to the market alternative, ensuring faster boot times and a smoother user experience right from the start. The perfomance can be further improved by cold starting the framework.
