MemoryActivity VS RunCat

Memory pressure and stats from Activity Monitor — right in your menu bar! - skw398/MemoryActivity

This cat runs at the speed according to the CPU usage of your Mac. By looking at its running, you can see how much your CPU load is.

Not present

Lightweight memory monitoring
MemoryActivity is a small, focused iOS library that lets developers quickly overlay real-time memory usage information on top of an app, without needing to integrate a large or complex profiling suite.
Easy integration
The library is designed to be simple to add to an existing iOS project, typically requiring minimal setup code to start displaying memory usage statistics, which speeds up adoption during development and debugging.
Useful for debugging memory leaks
By providing continuous visibility into an app's memory footprint while it runs, developers can more easily spot unexpected spikes or leaks in real time during manual testing or QA sessions.
Open source and free
Being hosted on GitHub and open source, developers can inspect the source code, modify it to fit their needs, and use it without licensing costs, which is beneficial for indie developers and small teams.
Non-intrusive UI overlay
The tool typically displays memory information as an overlay (e.g., a small HUD or label) that doesn't require navigating away from the app under test, allowing developers to monitor performance while interacting with the app naturally.

Limited scope
MemoryActivity focuses narrowly on memory usage display and does not provide the broader profiling capabilities (CPU, network, disk I/O, etc.) that more comprehensive tools like Instruments offer.
Potential maintenance concerns
As a smaller, community-maintained open source project, there is a risk of infrequent updates, lack of support for the newest iOS/Swift versions, or slower bug fixes compared to officially maintained Apple tools.
Not suitable for production use
Tools that overlay debug information are generally intended for development and testing only; using them in production builds could expose internal metrics or add unnecessary overhead, so developers must ensure it's stripped out for release builds.
Limited documentation
Smaller open-source utilities like this often have minimal documentation, which can make it harder for new users to understand advanced configuration options or troubleshoot issues without diving into the source code.
Platform-specific
The library is built specifically for iOS, so it cannot be used for cross-platform projects or apps targeting Android, web, or other platforms, limiting its usefulness in multi-platform teams.

Visual Performance Indicator
RunCat provides a unique visual cue for system performance by animating the speed of a running cat icon in the menu bar based on CPU usage, making it easy to notice at a glance.
Minimalistic Design
The software integrates seamlessly into the macOS menu bar with a simple and clean design, ensuring it does not clutter the user interface or require much screen real estate.
Low System Resource Usage
RunCat itself uses very little system resources, ensuring that it doesn't add to the load on your CPU while monitoring it.
Customizability
Users can customize the appearance and speed of the running cat icon, allowing for a personalized touch to the monitoring tool.

Limited Functionality
While it provides a fun and unique way to monitor CPU usage, RunCat doesn't offer detailed performance statistics or advanced monitoring features found in more comprehensive system tools.
Distracting for Some Users
The continuously moving cat icon might be distracting to some users who are more comfortable with static indicators or prefer a less animated interface.
Single-Platform Availability
RunCat is designed specifically for macOS, limiting its availability to users of other operating systems like Windows or Linux.
Requires Manual Updates
Users need to manually check for and update the software to access new features or improvements, which can be inconvenient compared to apps with automatic update functionality.
