Online Ruler 5 features
Xcode 7 features
  • Convenient Accessibility
    No need to search for a physical ruler; it's available instantly online whenever you need to measure something, from any device with a browser.
  • Free to Use
    There's typically no cost involved, making it a budget-friendly alternative to purchasing physical measuring tools.
  • Simple Interface
    Online rulers usually have a straightforward, easy-to-understand design that lets users measure objects quickly without complicated instructions.
  • Multiple Unit Support
    Many online rulers allow switching between units like inches, centimeters, and millimeters, offering flexibility depending on user needs.
  • No Installation Required
    Since it runs directly in a web browser, there's no need to download or install any software, saving time and storage space.
  • Integrated Development Environment
    Xcode offers a fully integrated development environment for macOS, iOS, watchOS, and tvOS. This integration includes code editing, project management, compilers, and debugging tools all in one application.
  • Interface Builder
    Interface Builder is a graphical tool included with Xcode that allows developers to design user interfaces visually. This can speed up the development process and allow for easier customization of user interfaces.
  • Swift and Objective-C Support
    Xcode provides robust support for both the Swift and Objective-C programming languages, which are essential for Apple's ecosystem.
  • Simulator
    Xcode includes simulators for all Apple devices, allowing for rapid testing and debugging of applications without the need for physical hardware.
  • In-depth Debugging Tools
    Xcode provides a comprehensive suite of debugging tools like breakpoints, stack trace analysis, and memory management tools, helping developers identify and resolve issues efficiently.
  • Performance and Profiling Tools
    Xcode includes Instruments, a powerful performance analysis and profiling toolset. This helps developers optimize the performance and memory usage of their applications.
  • Documentation and Resources
    Xcode has built-in access to extensive Apple Developer Documentation and resources, making it easier to find information and solutions related to Apple's APIs and frameworks.

Possible disadvantages

  • macOS Exclusive
    Xcode is only available for macOS, meaning that developers must use an Apple computer to build applications for Apple's platforms.
  • Resource Intensive
    Xcode can be demanding on system resources, particularly RAM and CPU, which can affect performance on older or less powerful machines.
  • Steep Learning Curve
    For new developers, Xcode can be overwhelming due to its complexity and the vast array of features and options available.
  • Update Frequency
    Frequent updates to Xcode can sometimes introduce new bugs or require developers to update their project settings and code to maintain compatibility.
  • Limited Cross-Platform Capabilities
    Xcode is designed specifically for Apple's ecosystems and provides limited support for cross-platform development, restricting its use for developers targeting multiple platforms.
  • Build Times
    Build times for larger projects can become lengthy, potentially slowing down the development cycle and time to market.

Questions & Answers

As answered by people managing Online Ruler and Xcode.

Why should a person choose your product over its competitors?

Online Ruler's answer

The calibration. Every other free online ruler I've seen skips this step entirely and just guesses your PPI, which means they're wrong on most devices. If you're measuring something where accuracy matters - a ring size, a small hardware part, a piece of fabric - being off by even 2mm causes real problems. Online Ruler is also completely free with no paywalls, no account required, and no intrusive ads covering the ruler while you're trying to measure something.

What makes your product unique?

Online Ruler's answer

Most online rulers just divide your screen's CSS pixels by 96 - an assumption from the 1990s when everyone used the same CRT monitor. On a modern phone or laptop that "1 inch" can be off by 30-40%. Online Ruler actually calibrates to your specific display. You hold your physical credit card (85.60mm wide worldwide by ISO 7810 standard) against an on-screen guide and adjust until they match - at that point the tool knows your screen's real pixel density and renders a true 1:1 scale ruler. You can also calibrate by entering your screen diagonal or picking your device from a database of 150+ models.

How would you describe the primary audience of your product?

Online Ruler's answer

People who need a quick, accurate measurement and don't have a physical ruler nearby. That's a wider group than you'd think - jewelry buyers checking ring sizes, crafters and sewers measuring fabric, 3D printing hobbyists verifying print dimensions, students doing geometry, and people shopping online who want to compare a product's listed size to something physical. The tool is available in 9 languages (English, Spanish, French, German, Portuguese, Italian, Japanese, Chinese, Russian) so the audience is genuinely global.

What's the story behind your product?

Online Ruler's answer

I ordered a ring online and measured my finger on an online ruler that turned out to be completely uncalibrated. Wrong size, had to return it. When I looked into why it was wrong, I found that basically every free online ruler on the internet makes the same mistake - they assume 96 DPI and call it a day. The actual pixel density of modern screens varies from about 90 PPI on a big desktop monitor to over 500 PPI on a flagship Android phone. So I built one that actually solves this with a proper calibration step. The credit card method came from realizing that one physical object almost everyone has in their pocket has globally standardized dimensions.

Who are some of the biggest customers of your product?

Online Ruler's answer

It's a free consumer tool with no accounts, so there's no customer data to pull from. But based on usage patterns and the guide content that gets the most traffic:

Jewelry buyers and makers measuring ring sizes at home Sewers and crafters measuring fabric and patterns 3D printing hobbyists verifying print accuracy Students needing a ruler for schoolwork Online shoppers comparing product dimensions to real objects
