Features and specs

What each product offers, as listed by its team.

ClojureScript 5 features
Ubi Timer 5 features
  • Immutable Data Structures
    ClojureScript provides persistent, immutable data structures which simplify reasoning about code and avoiding unintended side effects.
  • Functional Programming
    ClojureScript is a Lisp that encourages functional programming, aiding the creation of concise and predictable code.
  • Interoperability with JavaScript
    ClojureScript can interoperate seamlessly with JavaScript, allowing access to JavaScript libraries and facilitating interaction with existing JavaScript codebases.
  • REPL Driven Development
    The REPL (Read-Eval-Print Loop) in ClojureScript enables rapid testing and iteration of code, resulting in more efficient development processes.
  • Rich Ecosystem
    ClojureScript benefits from the rich ecosystem of Clojure libraries and tools, as well as those available in the JavaScript ecosystem.

Possible disadvantages

  • Learning Curve
    ClojureScript has a steep learning curve for developers new to Lisp or functional programming paradigms, which may limit its initial adoption.
  • Compilation Overhead
    Unlike JavaScript, ClojureScript code needs to be compiled, which can add complexity and overhead to the development workflow.
  • Smaller Community
    ClojureScript has a smaller community compared to more mainstream JavaScript frameworks, which can affect the availability of resources and support.
  • Tooling Complexity
    Integrating ClojureScript into existing projects can be complex, and its tooling setup might not be as straightforward as more established JavaScript tools.
  • Performance
    While generally performant, ClojureScript applications can sometimes face performance penalties due to the abstraction layers involved.
  • Simple Interface
    Ubi Timer offers a clean, minimalistic user interface that makes it easy for users to quickly set timers without unnecessary complexity or clutter.
  • Free to Use
    The tool is accessible without cost, making it a budget-friendly option for individuals and small teams looking to manage time without financial investment.
  • No Installation Required
    As a web-based tool, Ubi Timer can be accessed directly through a browser, eliminating the need for downloads or installations on various devices.
  • Quick Setup
    Users can start a timer almost instantly upon visiting the site, which is ideal for those who need a fast solution for time management tasks like Pomodoro sessions or study breaks.
  • Cross-Platform Accessibility
    Being browser-based, it works across different operating systems and devices as long as there is internet access, offering flexibility for users on desktops, tablets, or phones.

Questions & Answers

As answered by people managing ClojureScript 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
