Questions.
Do I need an account to upload?
Yes, browser uploads require sign-in. Trying the live sample or opening a share link does not. To run your own APK without an account, use the CLI trial, which needs Node.js and npm.
Which apps can I run?
Any installable Android APK, debug or release, that is compatible with an x86_64 emulator. Native libraries, hardware dependencies, and external services can affect whether an app runs.
Is Ramus a cloud phone?
No. Ramus is for testing Android apps you build or are authorized to test, so devices have no Play Store. The Acceptable Use Policy describes what is allowed.
Does the reviewer need to install anything?
No. A share link opens in any browser and gives them their own device with your app, or the one you are on, so send it only to the people you mean.
Does this support iOS or physical devices?
No. Ramus currently runs Android emulators only. It does not offer iOS sessions or physical Android devices.
What happens when I finish?
Ending the session releases the device and discards its state. It does not revoke a share link: a link that is still valid may offer a fresh launch later, subject to capacity, relaunch limits, and app availability.
