"buttons event recorder" is an iPhone app developed by Warren Burton, available for free in the Business & Productivity category. This app allows users to create and utilize custom single-purpose macro keyboards. By rotating the iPhone to landscape mode, users can view logs in large text, useful for displaying messages to others.

Ideal for tasks like field notes, research, or hobbies such as birding, this app enables users to record multiple similar events efficiently. Each recorded event is tagged with time and location, exportable in formats like KML, GPX, and CSV. Moreover, buttons can store more information than what is displayed on their labels, enhancing flexibility in recording detailed events.
