Store Software Updates on iOS
Whether an appropriate App Store listing appears depends on the store account's region. To download on iOS through that route, search by operator name and inspect any appropriate listing's identity and device compatibility information.
Install only when that entry is actually available, then open it and sign in. Updates for software acquired there use the store's controls. A missing listing can be addressed with website access through Safari, without changing account country details.
Use Android Guidance on an Android Device
If maintaining an Android installation, use the APK download and replacement guide and the guide to Android installation. An APK does not install on an iPhone, whose browser and store methods are separate.

Refreshing the Website Saved on iOS
Reopen a saved icon and reload its webpage to refresh the content. If you need to create the entry first, Apple's Safari steps can be grouped into three stages; the exact controls depend on system version and browser layout.
Once added, the icon can launch the website in a separate window using the website account. System and browser updates remain separate from a webpage reload. Users in India should distinguish this browser method from acquiring store software; website features depend on the site itself.
