Features and specs

What each product offers, as listed by its team.

SpeedCrunch 7 features
ChartSays 5 features
  • High Precision
    SpeedCrunch utilizes arbitrary-precision arithmetic, which allows calculations to be performed with a very high degree of accuracy.
  • Expression Parsing
    It can handle and parse complex mathematical expressions, making it suitable for advanced scientific and engineering calculations.
  • User-Friendly Interface
    The interface is clean and intuitive, allowing users to easily input and edit mathematical expressions without a steep learning curve.
  • Keyboard Shortcuts
    SpeedCrunch supports extensive keyboard shortcuts, which makes the application very efficient to use for experienced users.
  • Cross-Platform
    The software is available on multiple platforms including Windows, macOS, and Linux, providing flexibility for users on different operating systems.
  • Open Source
    As an open-source project, it allows for community contributions and transparency in its development, enabling users to trust and modify the software if needed.
  • Built-in Functions and Constants
    It includes a comprehensive list of built-in mathematical functions and constants, making it powerful for a wide range of applications.

Possible disadvantages

  • No Graphing Capabilities
    SpeedCrunch does not support graphing of mathematical functions, which can be a limitation for users who need visual representations of data.
  • Limited to Numerical Calculations
    It is primarily focused on numerical calculations and doesn't support symbolic mathematics, limiting its usefulness for some types of algebraic computations.
  • Lack of Documentation
    While it is intuitive for basic use, more advanced features may lack comprehensive documentation, making it harder for new users to fully leverage the software's capabilities.
  • No Mobile Version
    Currently, SpeedCrunch does not have an official mobile version, which could be a drawback for users who need to perform calculations on the go.
  • Customization Limitations
    There are limited options for customizing the user interface or adding new features beyond what is already included, which may be a downside for some users.
  • Fast chart interpretation
    As I understand it, ChartSays uses AI to analyze trading charts and return a summary of trends, patterns, and key levels. This can save time compared with annotating charts by hand, especially for people who review many charts. I could not browse the site, so check the exact features there.
  • Beginner-friendly explanations
    Plain-language readouts of chart patterns and price action can help newer traders learn what they are looking at. It can work as a learning aid alongside their own study of technical analysis.
  • Simple workflow
    A tool built around uploading or submitting a chart and getting an analysis back typically has a low barrier to entry. Users usually need no complex setup, coding, or indicator configuration.
  • Second opinion for trade ideas
    The analysis can serve as an objective cross-check on your own read of a chart. It may surface patterns, support and resistance zones, or scenarios you overlooked, which can reduce some personal bias.
  • Works across markets and timeframes
    Chart-based analysis can generally be applied to stocks, crypto, forex, and other assets on different timeframes. This makes one tool useful for traders who follow several markets.

Questions & Answers

As answered by people managing SpeedCrunch and ChartSays.

How would you describe the primary audience of your product?

ChartSays's answer:

We help operate ChartSays. It is designed for quality engineers, Six Sigma practitioners, and analysts who need to turn measurement data into understandable statistical results in a browser. Typical tasks include checking process capability with Cpk, monitoring individual measurements with I-MR control charts, and organizing a balanced crossed Gage R&R study using part, operator, trial, and measurement data. Worked sample reports help users inspect how results are presented and what needs care in interpretation. These are intended use cases, not a claim about current customers or a substitute for a correctly designed study. Explore the tools and sample reports at https://chartsays.com/.
