PhoneScan is a free utility app for iPhone that allows users to test the speed of their phone's processor and keep a log of the results. With this app, you can easily determine how fast or slow your phone is running and compare it to previous test results.

One of the key features of PhoneScan is the ability to compare the performance of different iPhones. If you're considering upgrading to a new iPhone, you can run PhoneScan on both your current and potential new phone to see exactly how much faster the new phone is. It's a great way to make an informed decision about upgrading.

In addition, PhoneScan also provides insights into the impact of iOS updates on your phone's performance. The log page displays all the previous test results along with the iOS version that was running during each test. This allows you to identify if a particular iOS update has had a positive or negative impact on your phone's speed.

Overall, PhoneScan is a useful tool for iPhone users who want to assess the performance of their phone's processor. Whether you're curious about the speed of your current phone, comparing it to a potential upgrade, or tracking the impact of iOS updates, PhoneScan provides valuable information to help you make informed decisions.
