What surrounds it you could not. The 3 things listed below take a company, not a weekend. That makes this kind of software worth paying for, not this one in particular: 46 of the 58 other website and product analytics tools grade higher. - You could make: Reports: an app builder makes this well. - You could not: Connections that pull numbers from dozens of other services. - You could not: It plugs into other products, Google Ads, Meta Ads and TikTok Ads among them. - You could not: AI features, unless you pay a model provider for each request yourself. A judgement by ToolGPA from this listing, by rules that are the same for every tool.
