BugShaker allows your users to simply submit bug reports by shaking the device. When a shake is detected, the current screen state is captured and the user is prompted to submit a bug report via a mail composer with the screenshot attached.
LaunchGate makes it easy to let users know when an update to your app is available.
You can also block access to the app for older versions, which is useful in the event of a severe bug or security issue that requires users to update the app.
Additionally, you can use LaunchGate to display a remotely configured message to users at launch which can also be used to temporarily block access to the app (i.e. during back-end maintenance).
