Review UI changes without manual tests

Many mobile app teams are slowed down by on-device tests and review only a fraction of critical use cases.
Our self-expanding UI gallery enables rapid feedback loops to detect visual issues early-on while drastically increasing test coverage.

Pre-release UI reviews

Ship updates faster

Easily share updates or prototypes with all stakeholders to demo options, discuss trade-offs, or clarify requirements.

No need to ship and install test versions or for anyone to have a physical device - Instant team reviews right in the browser.
A team conversation around the Appviewer web UI
Iterating on features used to involve a lot of slow manual testing. Now, we can verify visual changes really quickly and provide feedback to our developers very early on.
Saves a lot of back-and-forth!

Test more in less time

Catch visual bugs before they pose greater debugging challenges or even reach live users.

Make sure results align with designs across screen sizes and languages in our intuitive web app. Far more effective than manually testing only a fraction of use cases on physical devices.

Live Event Monitor

Capture real scenarios

Creating and maintaining test data is cumbersome. Our SDK discovers real-world UI scenarios to replay for screenshot capturing.

Our Event Monitor is also great for observing other behavior during manual tests, like data exchanges with your API or third parties like Google Analytics.

Run from any CI/CD

Appviewer is designed to be run from your CI/CD pipeline. Capture and publish snapshots on push, PR, or release, or filter by selected branches. But for quick alignment of development snapshots, you can also run locally.

How is this different from Figma, Adobe XD, Sketch or Zeplin?


While your design tools do a great job of capturing design requirements, they are not built to provide product insights for your team. Appviewer is a great complement in that it's purpose-built to show what things actually look like when implemented, not only how they are supposed to look. Designs are also limited to only a few scenarios. Appviewer integrates with your actual code, so it is an accurate representation of your application, incl. last-minute changes and states outside the happy path. It generally allows capturing a lot more real-world scenarios your users will encounter.

Does Appviewer replace manual testing?


Conducting proper functionality testing is essential. But deploying test versions, installing them, and cycling through the steps of all your test scenarios for each relevant test device is also very time-consuming. Appviewer can help you reduce the number of those manual testing cycles by providing a dedicated workflow to visually review changes. Your manual tests can then focus on the behavioral side of a change and are a lot less likely to surface visual bugs.

We already have automated testing in place, do we need this?


Automated tests help you to ensure that your most important features behave as intended. And while you can also stretch it to ensure that UI elements are, for example, present or clickable, they don't serve the purpose of verifying that everything looks as desired. Appviewer can nicely complement your existing test suite to help you ensure a perfect visual appearance of your app. Our integration is also based on automated tests, so you gain extra benefits from your testable architecture.

How is this different from screenshot testing?


Screenshot testing can help you avoid unintended visual changes. On the downside, also every intended UI change would make your tests fail. So developers need to constantly set new baseline snapshots. For most teams, this hit on developer productivity is an issue. Furthermore, those images can seriously bloat your code repository. Nevertheless, teams need a way to easily verify their app's UI, and that's not only a developer task.

Can we use Appviewer with Confluence, Notion, or our Wiki?


Sure! Having great product documentation can really help every product-related role in your company and new colleagues during onboarding. But it involves a lot of manual effort to keep it up-to-date and reliable. And while Appviewer is the go-to place to see your product at a glance, it can also help you update your already existing product docs in, e.g., Confluence or Notion.

Does Appviewer work with Jira Software?


You already use Jira or your favorite alternative for managing sprints. Appviewer helps to write more precise requirements and provide clearer feedback by referencing accurate snapshots along every step of your ticket progress. We might offer deeper integration in the future as well.

We are a software agency, is Appviewer also for us?


If you are working on a non-trivial application in close alignment with your client, Appviewer is a great way to frequently showcase your progress and collect valuable early client feedback without needing fully-working test versions. It also gives you confidence that every version you ship looks great on the majority of user devices.

Does it help with my outsourced dev team?


While outsourcing development brings flexibility and expertise, staying closely involved in the development process can be challenging. Limited opportunities to review progress and delays in feedback can lead to increased stress and costs. Appviewer accelerates feedback loops, enabling you to see results earlier and gain confidence that your project is on track. And the earlier you identify and address issues in the process, the cheaper it is by orders of magnitude.
