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.

Pros

“It is incredibly useful and detailed with regards to notifying us about bugs, errors and issues within our code or that users are having.”

Charlie P.

Director

“We deployed Rollbar in under an hour and the event lots started streaming in immediately.”

Dylan C.

Software Developer

“Within a day it had helped us solve several production issues.”

Dylan C.

Software Developer

Pros

“I used it to test an Android application before sharing it with others, and it saved me time compared to setting up multiple testing environments myself.”

Amara Y.

Software Developer

“The Test Management features help organize and manage testing activities effectively, while the automation capabilities significantly reduce manual effort.”

Prashant V.

Quality Assurance

“With improved support for native OS-level features like biometrics, social authentication, and push notifications, it would be an excellent end-to-end mobile testing solution.”

Niteen B.

Sr. Software engineer

Cons

“Also the graphs aren't that good.”

Brandi R.

clerk

“Their error reporting does not point to the right file or line. ”

Ryan B.

CEO

“I'm shocked that a company would recognize a bug, say they would fix it, and then not reply at all.”

Ryan B.

CEO

Cons

“Testing biometric authentication (Face ID / Fingerprint), social login flows, and push notifications is not fully supported or realistic on cloud devices, which can block complete end-to-end validation for React Native apps.”

Niteen B.

Sr. Software engineer

“The gap between listed devices and what can actually be launched reduced confidence in using the platform for scheduled validation or release work. While basic sessions and recording are straightforward to use, reliability of real devices has not met expectations, so it has been difficult to depend on.”

Eshani N.

Software Tester

We frequently encounter “Device Not Available,” Because we rely on manual testing across specific devices for global clients, predictable access is critical.
