## Description

Q-SYS UCI Viewer lets you control Q-SYS systems from an iOS device by using UCIs created in Q-SYS Designer. You can place nearly any system element into UCIs for quick control and monitoring, enabling on-the-go management of sources, cameras, lighting, projection, meters, screens, and more.

Note: This app works with the Q-SYS Platform and requires license activation on the Core processor. For details, visit qsc.com/uci.

## Review summary

Overall, reviews show serious reliability problems after updates: blank screens, inability to load or control volume/rooms, and frequent crashes, plus core/connectivity issues. These issues span iPad and iPhone, with some calls to revert to older versions. Positive notes are rare but include UI design quality and visuals on iPhone 4. The dominant sentiment is that updates improve theory but hurt stability, and developer responsiveness appears lacking.

### Pros

- Flawless UI design/display.
- Looks great on iPhone 4.
- Device compatibility across iPhone and iPad with usable visuals (as reported).

### Cons

- Post-update blank screen or failed to load ('downloading UCI…' loop) preventing access.
- Inability to control volume or interact with rooms after updates; UI shows but is non-functional.
- Frequent crashes on startup or first interaction.
- Connectivity issues with cores/values/meters; older cores not easily updated.
- Poor developer responsiveness and slow fixes.
