If you have a business account which is obviously public, you can view page insights, which tells you how many visitors your account has got in the past day or week, including the country of origin, but there is no part of the insights which talk about who has viewed the profile.
Then what about third-party apps on the App Store?
Yes, there are numerous apps available on the Google Play Store and the Apple App Store that claim to be able to tell you who has visited your profile, but this is not always the case. There is no app in the ecosystem that can provide you with information about who has viewed your profile, and if an app makes such claims, it is simply clickbait to attract users’ attention.
