Apteligent (formerly Crittercism) is a crash and bug reporting service that currently supports iOS and Android with HTML5, WP7 and BlackBerry versions.
Pro User Communication
Crittercism allows you to communicate directly to the end-user via features such telling users who experienced a crash that it has been fixed by an update.
They also have a easily implemented user feedback forum to receive bugs, feature requests or just general feedback from your users without having to leave the application.
The ability to enable users to communicate crashes or bugs directly to the development team will reduce the number of poor app store reviews.
