AudioToolsMax vs timer & stopwatch

AudioToolsMax is the complete professional audio test & measurement app with every tool completely unlocked and ready to use. Educational discounts are available under the Apple Educational Discount program. AudioToolsMax includes all of the additional optional modules, like SoundSource, SPL Graph, SPL Traffic Light, LARSA, Transfer Function, STIPA, Impulse Response, and more. It's the full package. We test every iOS device and calibrate the microphone level and frequency response for the best results. We have the ability to turn off the Apple low frequency filters, and on many devices we can measure up to 120 dB SPL. Add iTestMic, iPrecisionMic, or iAudioInterface2 for a complete professional audio and acoustic test and measurement platform. Actual reviews: “...AudioTools is a “how did I ever live without it” app”. “I think this application is the best I EVER purchased.” “I have used many thousands of dollars of complicated test equipment that doesn’t measure up to this app suite.” ***** Included in the app price ***** * SPL Meter A faithful reproduction of a classic analog SPL meter. Includes A and C weighting, and Fast and Slow ANSI decay modes. All filters meet or exceed ANSI type 1. * RTA A 1/3 and octave band Real Time Analyzer. Includes touch-GUI range control, a cursor, max/min bars, and noise curve overlays. * FFT Detailed acoustic analysis, up to 32876 points. View full detail or smooth to 1/24, 1/6, 1/3 or octave. Includes cursor, scalable graphics, and peak tracking. * Polarity Speaker polarity checker. Route the test signal to a speaker, and read the polarity of the speaker on the screen. * Delay Finder Measures the time it takes for a pulse to return from a speaker. * Generator Generates sine waves, square waves, white and pink noise. * Line Level Tests A line level measurement function and frequency counter. * Audio Scope A dual-channel audio oscilloscope that includes auto-triggering, variable gain and sweep rate, and storage of scope images. * Recorder A mono/stereo audio recorder with WAV and compressed formats and 8k-48k sample rate. Transfer files via WIFI. * File transfer of results via wifi to PC / Mac. * Audio Calculators * Smaart® Tools - Single channel module. The power of Smaart® on a mobile platform. Includes RTA graphs to 1/48th octave and Spectrograph. Split-screen on iPad. * Transfer Function -- Requires 2-channel interface. Two-channel FFT-based measurement. Allows you to analyze sound system performance with music or pink noise as the signal source. * ETC Energy Time Curve. Plot decay of an impulse over time, and compute RT60 time. Internal or External trigger. * Impulse Response Record and analyze an impulse or sine sweep, compute octave and 1/3 octave ETC, T30, C50, C80, CT, Definition. * LARSA Fast and accurate sine-sweep measurement of loudspeakers and rooms. * SPL Pro Digital SPL meter with ANSI Slow, Fast, Peak, and Impulse mode, along with LEQ. Includes A and C weighting, and all 10 octave band filters. * SPL Graph Plot second-by-second SPL level for up to 24 hours, and optionally record the audio. Also, add the optional Octave Band Logging upgrade to elevate this tool to rival any professional logging SPL Meter. * SPL Traffic Light Monitor live sound levels SPL and Leq and see status in a simple green-yellow-red display. * STIPA Speech Intelligibility Meets the current NFPA code standards for testing evac systems and schools. * Speaker Distortion Measure THD+n of any driver. * THD+n (requires iAudioInterface) * Impedance Meter and Plot (requires iAudioInterface) * Phase Meter * Amplitude Sweep

Set multiple timers and stopwatches at the same time. Give each a name and let it run independently. Mark timers and routines as favorites to keep them at the top of your library, and search by name. Duplicate a timer, a whole routine, or an individual stage to create your next setup. Favorites sync through iCloud. Start or resume saved timers and routines by name with Siri and Shortcuts. Add a small Home Screen widget for a favorite: tap Start to open Timer and start or resume that item. Starting an already-running item leaves its progress intact. Build routines for focus, workouts, and breaks. Combine named stages with their own durations, repeat rounds, and choose automatic transitions or start each stage yourself. Try the Pomodoro example or a 40-minute workout followed by a 10-minute break, then make it your own. One routine runs at a time on each device, alongside your ordinary timers. Start a Quick Timer with a preset or minutes slider. Personalize all four presets and choose whether completed Quick Timers are removed automatically. Start timers with Siri and Shortcuts, or use configurable controls on supported systems. On iOS and iPadOS 26 or later, grant alarm permission to use AlarmKit alerts with system countdown and Lock Screen controls. Notification alerts remain available on earlier supported systems or when alarm permission is not granted. Automatic routines use notifications for intermediate stage cues. Keep timers, settings, history, and saved routines on your device and sync them with your other devices through iCloud. A routine's running session stays on the device where you started it.
