There are hundreds of new apps everyday for iOS.... Although I suspect that wasn’t the question you meant to ask. There are various apps relating to Tello and Tello EDU on the iOS App Store. Have you tried searching?
If you mean “are there any third-party iOS apps to replace the official Tello app from Ryze, of the equivalent quality and as feature-rich as TelloFPV for Android?”.. then No. There isn’t.
