Poll At Once is a free iPhone app developed by Frank Zielen. This simple and easy-to-use app allows users to conduct polls with live audiences in academic lectures, industry workshops, or other events to gather instant feedback, evaluations, or votes.

To use Poll At Once, simply initiate a poll and share a code with the attendees who also need to have the app installed. No registration or login is required, making it quick and hassle-free. Participants can answer the poll by selecting options A, B, C, or D, with their responses being completely anonymous. The results of the poll are displayed in real-time on your phone, allowing you to track the responses as they come in.

One of the key features of Poll At Once is that every poll is automatically closed after 30 minutes, ensuring that the results are captured within a specific timeframe. This is particularly useful in time-sensitive situations where quick feedback or voting is required.

While the app is free to use, there is also an in-app purchase option available for users who want to organize and manage all the polls they have initiated. However, the free version of the app is fully functional and can be used independently.

Developed by Frank Zielen for personal use, Poll At Once offers a rudimentary yet effective solution for conducting instant polls with live audiences. Users are encouraged to provide suggestions for improvement, as the developer is open to feedback and continuously working on enhancing the app's features.
