UbiStage Timer turns iPhones and iPads into a synchronized stage clock โ€” the same time on every display.

Many teams start timer apps manually on several devices, and the clocks drift apart. UbiStage Timer solves this: one device becomes the host, all others sync automatically, down to the millisecond.

Devices find each other automatically over local Wi-Fi (Bonjour). No setup, no pairing, no account, no internet connection required โ€” just open and go.

One host, unlimited screens: use iPhones and iPads at the same time as stage clocks, all showing the same time, fully local.

An automatic color change (white โ†’ yellow โ†’ red) gives speakers an intuitive sense of remaining time at a glance. The host can also send short text messages directly to all displays for spontaneous corrections during the event.

Ideal for conferences, stage productions, trade shows, churches, and livestreams. Free public beta on the App Store: free with one display, with a Timer Key unlocking unlimited synced displays.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.
