Using someone else's Wi-Fi on iphone, can they still see your app history?

Yesterday I went to work with my friend and I used the places' Wi-Fi, I'm at home right now and no longer using their Wi-Fi, can they track my history and app history in my iphone even if I'm not using their Wi-Fi anymore?

While you are on their network they technically could see it in a few ways. Whenever you are connected to someone's Wi-Fi they can track all information being sent and received from the internet. I highly doubt anyone would know how to do this, but it is possible.Using someone else s wifi on iphone, can they still see your app history
