vashTimer: A Multi-Purpose, Multimodal Mobile App For Maintaining Passage of Time by means of Visual, Auditory, Speech, and Haptic Alerts

Effective time management during presentations is challenging, particularly for Blind and Low-Vision (BLV) individuals, as existing tools often lack accessibility and multimodal feedback. To address this gap, we developed vashTimer: a free, open-source, and accessible iOS application. This paper demonstrates the design and functionality of vashTimer, which provides presenters with a robust tool for temporal awareness. The application delivers highly customizable alerts across four distinct modalities: visual, auditory, speech, and haptic; and supports multiple configurable intervals within a single session. By offering a flexible and non-intrusive time management solution, vashTimer empowers presenters of all visual abilities. The implications of this work extend beyond public speaking to any professional, such as a clinical therapist, who requires discreet temporal cues, fostering greater independence and focus for a wide range of users. This demonstration serves as the foundation for a planned formal user evaluation.
