Subscription ware - for full features – PDF Viewer - Annotation Expert Review

Absolutely no reason to subscribe; it’s just a way for the creators to reach into your wallet and stay there. While I can understand why a subscription could be used for recurring costs like a server or online storage, it makes no sense for a PDF viewer. Recommend you look at PDF Expert or some other single charge app. Deep six this unless the free features are useful and you don’t mind seeing ‘Pro’ ads everywhere.
