There are a few things that separate IObit from similar products. On the plus side, its optimization and tune-up toolset is one of the best out there. But its overall quality is reduced by the fact that it tries to upsell you on other products from within the premium app. Most competitors don’t do this kind of thing. For example, it doesn’t come with a VPN, but it promotes a mediocre third-party VPN. That said, IObit offers a lot of features while being significantly less expensive than most competitors.
