Thank you for your message.
I apologize for a somewhat primitive interface in the mobile Viewer. Currently, the improved mobile Viewer version is in development. We are going to significantly improve it, namely, implement a full-fledged address book that can be synced with the desktop Viewer.
In addition, we are currently waiting until the manufacturer of the development environment we use to release the 64-bit compiler (it's promised to be released very soon), as we need to build the Android client using a 64-bit compiler so we could resolve some Android version issues. Once the manufacturer releases it, we will immediately update the Android client.
Sorry for the inconvenience.
