Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

Software for solving and editing mathematical calculations
PTC Mathcad Prime is sold in either locked or floating licenses as an annual subscription. Floating License: A license that can be used by one user at a time. Referred to as a “Concurrent User” in the licensing basis table. Floating licenses enable multiple users to “share” licenses on the same server, as long as the number of concurrent users doesn’t exceed the number of licenses purchased. Floating licenses are great for teams that need flexibility across multiple users or machines. Locked License: A license that is limited to being used on the computer on which it is installed. Referred to as a “Designated Computer” in the licensing basis table. Locked licenses are ideal for individual users or setups where the software is always used on the same workstation.
