For iOS

Availability on iPhone and iPad depends on the platform's current support and App Store availability. Do not install unofficial configuration profiles or unknown applications to bypass Apple's security.

iPhone / iPad checklist

Check the official App Store if an iOS application is offered.
If web access is supported, use Safari or another trusted browser.
Never provide your Apple ID password to a third-party website.
Review the platform's current terms and eligibility requirements.

If no official iOS application is available, do not use random IPA files or unknown installation services.
