PL NetTools vs Resonote

PL NetTools is the network toolkit for iPhone, iPad and Mac: a full domain diagnosis, a connection test and the classic tools, built on native networking, with no account. DOMAIN DIAGNOSIS • Enter a domain or a URL: the app checks site, email and domain together • Site: DNS, ports, certificate and chain, HTTP, security headers, www, IPv6, CDN • Email: MX, SPF, DKIM, DMARC, MTA-STS and TLS-RPT • Domain: expiry and registration (RDAP and WHOIS), DNSSEC, name servers, CAA • Problems sorted by severity, each with an explanation and a fix, decided by precise rules, not by a model CONNECTION TEST • Parallel pings to the router and to the Internet, with a response-time chart • Tells you whether the problem is in the local network or in the line, and spots a transfer in progress on the device ASK (iOS and macOS 27 with Apple Intelligence) • Describe the problem in words, for example "emails from client.com go to spam" • The app picks and runs the checks and writes a plain-language report • A ready-to-send ticket, in English or Italian, for whoever has to act: hosting, email, registrar or DNS, internet provider • Uses the on-device model or Private Cloud Compute; your public IP is never sent TOOLS • IP: your public IP or a domain's, with location, network and ASN • Native ICMP Ping and Traceroute, with chart and hop names • DNS: the main records in parallel, with readable HTTPS/SVCB and CAA • Whois with RDAP and the expiry date up front • TCP Port: check whether a port answers • HTTP/TLS: server response and the full certificate, with chain and CAA REPORTS AND SHORTCUTS • Diagnosis, Connection test and tools can be shared as Text, Markdown or PDF, ready to attach • Shortcuts actions: diagnosis, connection, domain expiry, certificate and more, in automations too PL NETTOOLS PRO Free: IP, Ping, DNS, Whois, Traceroute, the Diagnosis outcome with the problem titles and the Connection test chart. With Pro (yearly subscription, one-week free trial): explanation and fix for every problem, all the diagnosis data, full Connection test measurements, TCP Port, HTTP/TLS, Ask, reports and the Pro Shortcuts actions. PRIVACY No account, no ads, no tracking. The app does not collect personal data: requests go from your device straight to the public services you query.

Resonote is a sound analyser for musicians and acousticians. See the spectrum of anything the microphone hears, tune your instrument, measure sound levels and how long a room rings. Tap any peak to hear it. SPECTRUM AND SPECTROGRAM • Live spectrum from 20 Hz up, with the main peaks marked • Low-frequency detail, Off, Normal or Fine: bins down to 1.5 Hz apart in the bass, and 3 to 12 Hz up to about 1.2 kHz, on the chart and the spectrogram • Narrowband, or 1/1, 1/3, 1/6 and 1/12 octave bands (IEC 61260) • Tap a peak for its frequency, note, cents and harmonics • Hear any peak as a pure tone, made louder where the ear is less sensitive • Pinch to zoom: the zoomed chart resolves down to 0.7 Hz • Spectrogram with a log, linear or piano keyboard axis, in six colour scales • A, C and Z weighting, Fast, Slow and Peak hold, FFT size 512 to 8192 • Keep a reference spectrum on screen to compare before and after • Turn the phone sideways for taller charts and a five-second waterfall under the spectrum TUNER • Notes: tune a whole chord or section, up to four notes at once, each on its own lane, the lowest on the left • 41 instruments and voices, and a general mode: orchestral woodwinds, brass and strings, saxophones, acoustic guitar, piano, timpani, marimba, vibraphone, xylophone, glockenspiel, bells, and six singing voices from soprano to bass • Each instrument has its own overtone pattern, so a piano string's stretched partials or a bell's partials read as one note instead of several • Show partials 2 to 4 beside the note, each tuned on its own lane, with five seconds of history • A sung note reads at its centre, steady through vibrato • Tap the reading to hear the note in tune • Note names with sharps or flats, German (B and H) or do re mi, set automatically by your phone's language • Transposes for B-flat, E-flat and F instruments • Concert pitch 440 or 442 Hz, or your own; green within ±3, ±5 or ±10 cents SOUND LEVEL METER • dB SPL with A, C or Z weighting, Fast or Slow, Leq, Lmax and L90 • NR and NC ratings of background noise, and prominent tones in third octaves (ISO 1996-2) • Calibrate with your measurement microphone's calibration file, its sensitivity in mV/Pa, or a sound calibrator • Uncalibrated, it shows an estimate and tells you how far off it may be REVERBERATION TIME • EDT, T20 and T30 per octave (ISO 3382) • Measured from a hand clap or a balloon pop, with a step-by-step guide: where to stand, when to clap • Average up to ten measurements and see the spread in each band RECORDING • Record the raw microphone signal as a lossless WAV file, at the device's own sample rate • Your recordings are in the Files app, under On My iPhone BUILT TO MEASURE On iPhone, Resonote switches off the voice processing iOS normally applies to the microphone, so the levels you see are what the microphone really picks up. It works with the built-in microphone and with wired or USB measurement microphones. With AirPods connected, it still measures with the iPhone's own microphone. No account, no ads, no tracking. All analysis happens on your phone.
