I want to ask
if I have some data on edge impulse and want to use it to make an application (ios app)
Is it possible?
Yes, you can train a machine learning model on Edge Impulse and deploy it as a library to use in a phone application. However, keep in mind that at this time, you are limited to exporting the library in a few different formats. The C++ and wasm exports are probably the most interesting to you. As we do not support Swift (for the time being), you will need to find a way to compile/link either the C++ or wasm library that you export.
Other export formats are available, and I recommend reading about them here: Deployment - Edge Impulse Documentation
