Waveform Panel
Waveform and performance, backed by data
Draws real-time waveforms of frame rate, heap memory, task load and other key metrics right on the screen, so performance regressions are obvious at a glance. Any metric can be pinned as a persistent line to compare before and after a change.
Auto-refresh and sampling throttle are built in: computation stops when you leave the page and resumes on return, so sitting on the performance page for hours never slows the rest of the device.
On-screen interface
A recreation of this page on the 2.41-inch AMOLED display (600 × 450). Actual interaction and layout follow the latest firmware.
Key capabilities
Multiple metrics on one screen
Frame rate, heap and task load side by side for intuitive trend comparison.
Frame-time breakdown
Screen flush, buffer clear and content time shown separately to pinpoint congestion.
Low-overhead sampling
Computation stops when you leave the page, so monitoring never becomes the burden.
Exportable data
Performance snapshots ride along with reports and can be reviewed on the platform.
Technical specs
Typical scenarios
Before/after comparison
Read frame time on the same page after changing render logic to verify the optimization.
Continuous stress test
Run for hours and watch whether the memory curve slowly declines, exposing leaks.
