For someone with an iPhone, certain products and services are essential if they are heavily dependent on this type of phone. Of of the more useful is FoneLab products, which are utilities for this proprietary operating system. The controversy is that most products cost good money while competing operating systems might offer similar services for free or a lower cost. As an example, their data recovery service might cost $60 or more. To see if it is worth it, check out a Fonelab Review by a variety of customers.
In some cases, there might be an alternative to FoneLab products. On the other hand, there might not be. Since the iPhone is a property and not just a platform for a more broadly used operating system, there is a tendency by the company to impose a price on everything. Sometimes you have to buy a service or find a way to do without it.
