This app is designed to solve a single problem: how to take long screenshots on an iPhone. It offers two stacking modes: naive and smart. In smart mode, the app analyzes adjacent screenshots to find the best positions for stacking them seamlessly. However, if there is no obvious pattern in the screenshots, the app may fail to produce a perfect result. In that case, try taking another screenshot with a larger overlapped region that has clear edge-like patterns.

We are continuously working to optimize the underlying matching algorithm and improve the app's performance. If you have any suggestions or encounter any bugs, please don't hesitate to contact us at andreheat30@gmail.com.
