SysScope vs AudioSpectrumWaterfall

SysScope is your iPhone's complete diagnostic dashboard — real-time vitals, powerful network tools, motion sensors, and home screen widgets in one beautifully designed app. OVERVIEW See your device name, model, hardware identifier, iOS version, and build number. Monitor CPU load across every core with a live per-core breakdown and up to 2 hours of CPU history. Check uptime, timezone, language, locale, orientation, and IPv6 address. POWER Track battery level with animated gauges, charging state, and low power mode. Get live discharge and charge rate estimates with predicted time-to-empty and time-to-full. Monitor thermal state from Normal to Critical, and view screen brightness and refresh rate in real time. MEMORY See your app's RAM usage alongside total system RAM, with a full memory breakdown — wired, active, inactive, compressed, and free — shown as a color-coded bar. Storage is covered too: total, used, and free space at a glance. NETWORK TOOLS A complete toolkit for network analysis: • Live WiFi details — SSID, BSSID, signal strength • Cellular carrier and radio technology (4G/5G) • Internal and external IP, subnet mask, and gateway • Download and upload speed tests • Ping latency measurement • DNS lookup and Whois query • Custom ping to any host • Visual traceroute • Port scanner with 22 common service labels • LAN device browser • Wake-on-LAN sender All results are saved to a scrollable network history log. SENSORS Live motion data — gravity, user acceleration, rotation rate, magnetometer readings, barometric pressure, and relative altitude. Track pitch, roll, and compass heading in real time. Monitor microphone input level and scan for nearby Bluetooth devices with signal strength ratings. TOOLS Generate audio tones at any frequency for speaker or hearing tests. Track GPS coordinates with altitude, speed, course, and accuracy. WIDGETS Add a home screen widget to surface your key stats without ever opening the app. ALERTS Set custom thresholds for battery level and storage. Enable thermal state alerts. DeviStats notifies you when your device needs attention. EXPORT Share a full device stats snapshot as plain text — useful for support tickets, diagnostics, or device reports. All metrics refresh every second. Battery, CPU, and RAM history is preserved for up to 2 hours and persists across sessions. Supports dark, light, and system theme.

A real-time audio analyzer for iPhone and iPad. Five panes cover spectrum, waterfall, oscilloscope, peak list, and note/chord detection — pick any combination and arrange them in a custom layout. PANES Spectrum — live magnitude spectrum in three drawing styles (Trace, Line, Bars), peak-hold trace, peak markers, and a drag-anywhere cursor showing frequency, level, and nearest note. Waterfall — scrolling spectrogram with six color maps and adjustable scroll speed. Time Domain — oscilloscope with rising-edge trigger, automatic vertical gain, and min/max envelope drawing. Notes & Chords — detected fundamentals with cents-accurate tuning meters and chord name readout. Peak List — top N interpolated spectral peaks with frequency, level, nearest note, and cents offset. Panes stack vertically and split into two columns on wide, short windows (iPad landscape, phone landscape). Five built-in layout presets are included: Spectrum + Waterfall, Scope + Spectrum, Musician, Analyser, and Everything. ANALYSIS CONTROLS FFT size from 256 to 32768 points. Window functions: rectangular, Bartlett, Hann, Hamming, Blackman, Blackman-Harris, flat top, Kaiser. Exponential averaging and adjustable refresh rate. Live readout of frequency resolution (Hz/bin) and window length (ms). Amplitude scale: linear or dBFS, with adjustable level range. Frequency scale: linear or logarithmic, with adjustable frequency range. Spectrum style: Trace (every FFT bin plotted individually, no resampling) or Line/Bars (per-pixel peak or average detector). NOTE AND CHORD DETECTION Harmonic-comb analysis with iterative spectral subtraction identifies fundamental frequencies and matches them against 19 chord templates across all 12 roots, including slash-chord naming. A spectral-flatness gate skips pitch detection on broadband, non-tonal input (percussion, breath, room noise), with an adjustable sensitivity threshold. The spectrum, waterfall, and peak list always display the raw, unmodified spectrum — harmonic reduction is applied only to the note and chord readout. AUDIO INPUT Works with any input source exposed by the system: built-in microphone (including individual top/bottom/front/back elements where supported), wired headsets, USB audio interfaces, and Bluetooth headsets. Sample rate can follow the hardware or be fixed at 8, 16, 22.05, 32, 44.1, 48, or 96 kHz. Automatically handles route changes (headphones unplugged, Bluetooth reconnects) and interruptions (phone calls). SIGNAL GENERATOR Built-in generator produces sine, sawtooth, square, triangle, white noise, pink noise, a logarithmic sweep, or a major triad — useful for testing scale settings and window behavior without external audio. Nothing is routed to the speaker. DISPLAY CONTROLS Freeze the live display at any point, and start or stop capture manually. A status bar shows RMS/peak level with a clipping indicator, the current audio route, sample rate, FFT size, Hz/bin resolution, and window length. PRIVACY Audio is analyzed in real time on-device only. It is never recorded or transmitted. REQUIREMENTS iPhone and iPad, iOS 17.0 or later. Microphone access required for live audio capture. English only.
