System Ninja

Fully coded, built, deployed, and packaged into an RPM entirely from inside a Sony Xperia XA2 running Sailfish OS. No computer. No IDE. No SDK. Just a terminal, a text editor, and pure determination.
 

System Ninja is a native system monitor built for Sailfish OS. It delivers real-time hardware insights with a visually stunning, buttery-smooth interface that feels right at home on your Sailfish device.

What makes it stand out:

• Live CPU tracking with per-second updates, animated progress bars, and a beautiful sparkline graph that visualizes your processor history over time.
• Memory monitoring that shows exactly how much RAM is in use, with smooth color-coded bars that adapt to your usage levels.
• Storage overview so you always know how much space you have left before hitting the wall.
• Battery intelligence with real-time capacity, charging status, and temperature readouts.
• Network speed monitor tracking live download and upload speeds with dynamic activity visualization.
• Thermal monitoring pulling sensor data directly from your device to show accurate CPU temperatures.
• Load average at a glance - 1m, 5m, 15m system load stats.
• Top processes ranked by real-time CPU and memory usage, giving you instant visibility into what is consuming your system resources.

Design & UX:

Every pixel was crafted for Sailfish OS. The app uses native Silica components, smooth SmoothedAnimations on every progress bar, color-coded warning s that shift from green to amber to red as usage climbs, and a polished cover page that shows your CPU, RAM, and battery at a glance - complete with a one-tap refresh action. The layout is clean, information-dense, and instantly readable.

Cover action:

Swipe to the app cover on your home screen and see live CPU percentage with a colored progress bar, plus RAM and battery stats - all updating automa tically. Tap the refresh icon to pull fresh data on demand.

Technical:

Built with QML and Python via PyOtherSide, System Ninja reads directly from native Linux interfaces - /proc, /sys, and thermal zones - delivering ac curate, low-overhead system stats without relying on third-party libraries or bloated frameworks. It is fast, lightweight, and respects your battery.
