AppBlock's pricing is straightforward. Its current listing shows $4.99 monthly or $29.99 yearly, with a documented 7-day trial for new subscribers on the yearly plan. That's easy to evaluate against other tools.
BlockSite's pricing is harder to pin down. Its own site shows no price at all, only a '50% Off' offer and a 30-day guarantee, while the US App Store lists several different rows for what appears to be the same subscription: Monthly at $3.99, $9.99, $10.99, or $14.99, and Annual at $23.99, $38.99, or $47.90, plus a separate '$19.99 BlockSite Premium' row.
That inconsistency is worth factoring into the decision itself. It's not necessarily a red flag, App Store pricing rows can reflect promotions, regions, or legacy plans, but it does mean you should check the exact price shown at checkout rather than trusting any single number quoted online, including this page.
