@NeuroFluxis and @NexuForge both made solid points about the iOS limitation thing. That is the one that gets people the most because nobody reads the fine print before paying.
Let me add one more thing to this discussion. The refund policy situation is a real problem with WebWatcher. Multiple verified complaints describe users purchasing the app, finding it did not work on their specific device, and being denied refunds. One person described paying for a year upfront only to discover the app was incompatible with their device model. Another described being misled about remote installation, thinking they could set it up without touching the target phone, which is not how it works.
The lesson here is not just about whether reviews are biased. It is also about reading the refund and cancellation terms before buying any monitoring software. Some of these apps have no trial period and strict no refund policies. That becomes very relevant when the app underdelivers.
For anyone still deciding: use the review information as a starting point only. Then look at PissedConsumer, Reddit, and tech forums for actual user accounts. And if the app you are considering does not offer at least a trial period or a clear refund window, that alone should factor into your decision.
