under text size my I phone 6 says apps that support dynamic Type will adjust to your preferred reading size when I tried the app store - did not see

Hi jrtsIphone4,

We see you're looking for steps on how to find and install apps on your iPhone. That's certainly a core experience for using the device, and we'd like to help out.

To start, you can find steps on how to find and install apps on your iPhone here: Download apps and games on your iPhone or iPad

We noted you had a question about the Dynamic Type feature. There isn't a current way on determining if a particular app will support it prior to downloading. However, you may wish to leave some feedback, if desired, on Apple's feedback page here: Product Feedback

Take care!
