Questions & Answers

As answered by people managing Bookmark OS and Ubi Timer.

What makes your product unique?

Ubi Timer's answer:

Ubi Timer brings timing directly into PowerPoint, so presenters do not need to switch to a browser, phone, or separate desktop timer. It supports countdown and stopwatch modes, works during Slide Show, and can be used per slide or across sections of a presentation, which makes it especially useful for lessons, workshops, rehearsals, and live talks.

Why should a person choose your product over its competitors?

Ubi Timer's answer:

Choose Ubi Timer if you want a timer that feels native to PowerPoint instead of bolted on. It is designed to be quick to set up, easy to style to match your slides, usable on Windows, Mac, and PowerPoint for the web, and reliable in live presentation settings without needing to leave your deck. It also offers a free version and a free EDU option for verified schools.

How would you describe the primary audience of your product?

Ubi Timer's answer:

Ubi Timer is built for teachers, trainers, presenters, and speakers who use PowerPoint and need better control over timing. It is especially well suited for classrooms, workshops, meetings, practice sessions, and any presentation where staying on schedule matters.

What's the story behind your product?

Ubi Timer's answer:

Ubi Timer was created out of frustration with standalone timers and makeshift PowerPoint timer setups built from animated slides. The goal was to create a cleaner, easier, and more reliable way to manage time inside PowerPoint without disrupting the presentation experience.

Which are the primary technologies used for building your product?

Ubi Timer's answer:

Ubi Timer is built as a Microsoft PowerPoint add-in for Microsoft 365 and Office, designed to work directly inside PowerPoint across supported Windows, Mac, and web environments. I could not find a trustworthy public source naming the full internal stack, so this answer is safest for a public listing.

Who are some of the biggest customers of your product?

Ubi Timer's answer:

Teachers and schools Corporate trainers Workshop facilitators Public speakers and presenters Teams using PowerPoint for meetings and rehearsals
