IOS AntiSpy App + subscription + pixel after trail

I'm looking for an experienced iOS engineer with a track record of developing apps on the App Store as I need someone to create an anti-spy app tailored to the needs of my business. The app will have to be created from scratch and it requires a subscription payment structure as well as post-trial tracking of user behavior with pixel and analytics. The developer will need to be well-versed in designing apps for the iOS platform. This will be a long-term project and I need someone with dedication and skill to get the job done.
