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.

Cardknox overview
What is Cardknox?
Cardknox offers integrated payment solutions for developers, ISVs, and SaaS providers. With flexible payment solutions for every channel, Cardknox makes it easy to integrate payments with your e-commerce website, POS software, or mobile application.
Partners enjoy competitive residuals, white-glove developer support, and tools to easily manage your merchant portfolio. Partners can choose from Cardknox’s traditional ISO model or our payment facilitator offering, Cardknox Go.
Merchants can utilize the Cardknox Merchant Portal and the Cardknox Mobile App to search and process transactions, enable recurring payments, and generate business reporting.
The Cardknox Mobile App
The Cardknox Mobile App is an all-in-one point-of-sale and management tool. Take payments wherever your business takes you. Key in card data or snap a photo to capture card details on the go, or use our compatible mobile EMV card reader to give your customers even more payment options - from chip and contactless cards to magstripe cards.
The app also syncs with your Cardknox Merchant Portal account, keeping you up to date on all of your business’s transactions. And for developers, our Mobile SDK can be used to integrate the app’s features into their clients’ apps.
