This app combines an oscilloscope, FFT analyzer, and signal generator. It allows real-time observation of audio device frequency characteristics and waveform analysis. Features include multiple oscilloscope modes, detailed FFT spectrum analysis, and various signal generation options.
- Oscilloscope with Normal, Trigger, and Single modes
- FFT analyzer with peak level, frequency, and THD display
- Signal generator for sine waves, white noise, and sweeps
- Real-time FFT synchronization sweep mode
- Screen capture and save functionality
- Adjustable sensitivity and time span

Three tools (oscilloscope, FFT analyzer (spectrum analyzer), signal generator) are included in the e-scope 3-in-1. Please take a look at this video. Basic functions: http://youtu.be/WPm4Dbz0WAo Automatic measurement add-on: http://youtu.be/K6_stq_t2zQ It can observe the frequency characteristics of audio devices using an FFT analyzer and a signal generator. Observation of frequency characteristics in real time is possible by using the FFT synchronization sweep mode. inputs are acquired via the built-in microphone or headset connector. -Oscilloscope The oscilloscope has three modes. * Normal mode: It is suited to observe music waveforms. * Trigger mode: This mode is suitable for repeated waveforms such as sine wave. You can observe waveforms in stationary condition. * Single mode: This mode is suitable for observing one-time waveform such as impact sound. You can change the sensitivity and time span by pinch out and pinch in. -FFT analyzer It is possible to analyze the frequency spectrum of an input signal. The peak level and the frequency are displayed at the top of the screen. The display can also be used as a simple frequency counter when you enter a single signal. In addition, the THD (Total Harmonic Distortion) value is displayed at the bottom left of the screen. By pressing the resolution button, you can select the frequency resolution free three types. When you press the peak hold button, the maximum value of the signal that you are currently viewing is displayed in a red line. -Signal generator The signal generator can be used to generate a signal of four types: Sine wave of 1Hz to 20kHz, White noise, Linear sweep and Log sweep ranging from 20Hz to 20KHz. When you tap the area that displays the frequency or sweep time range, a picker will appear. Please set the appropriate numbers in it. By using the mode [optimized for FFT], it can automatically change to a frequency with highest FFT accuracy. Please use the feature if you want to accurately measure the THD. While the frequency is displayed, it will be ignored when you enter 0000. During the FFT synchronization sweep mode, when you enter 000 as the display start time for the sweep time display, the FFT synchronization sweep mode will be activated. It will change the frequency at high speed in FFT analysis unit time (less than 0.1 seconds) . It is possible to observe the frequency characteristic in real time in this mode. When you press the Copy button at any mode, you can capture screen and save it to a camera roll.

Recommended for: ・Those who want to practice instruments or transcribe by ear ・Those who want to quickly record phrases and ideas on the go ・Those who want to easily create songs in a mobile environment ・Those who want to transfer songs created on an iPhone or iPad to a computer DAW software ・Those who want to input performance infomation while looking at sheet music ・Those who want to record their own performance ・Those who want to easily edit MIDI data and sound data ・Those who want to automatically play electronic instruments (synthesizers, digital pianos, rhythm machines, etc.) or record their performance ・Those who want to use Audio Unit (AUv3) plug-in sound sources and audio effectors, midi effectors ・Those who want to learn MIDI ・Those who want to view and analyze MIDI data output from electronic instruments ・Those who want to try voice percussion ・Those who want to play Standard MIDI Files (SMF) ・Those who have used DAW software in the past but gave up ・Those who want to create a medley of their favorite songs from a music CD ・Those who want to easily record vocals along with karaoke songs from music CDs ・Those who want to play music and sound effects at their own timing using the screen touch or an external MIDI controller ■Key Features [Collaborate Other DAW Software] ・Supports the export function for dawproject files. Quickly turn ideas into songs in a mobile environment, then use DAW project file import functionality (e.g., Bitwig Studio, Cubase ,Cubasis, Studio One) to create and polish your songs. *For important information on handling dawproject files, please refer to the website [https://uk-868home.my.canva.site/]. ・Supports playback, editing, and saving of SMF (Standard MIDI File), which can be linked with a DAW on a PC. ・You can export the performance of audio phrases registered in a song or MIDI phrases output to a SoundFont source to a Wave file. [For Performance] ・Play, edit, and save audio that combines multiple Wave files. (You can also import songs stored in the Music library of your iPhone or iPad.)*Songs downloaded from paid sites are not included. ・It supports audio capture using the 16 pads on the iPhone or iPad's built-in microphone or audio interface, pad touch playback, loop playback, and real-time recording of performances using pad and slider operations. ・By creating a PlayList, you can play multiple songs consecutively. Songs from this app, SMF, and Wave files can be registered in a PlayList. [Use Audio Unit (AUv3) plugin, Sound Font] ・You can create sounds by assigning commercially available AudioUnit V3 compatible instruments (sound sources such as synthesizers) and effects available for iPhone and iPad to the Audio Mixer. In addition, it can also handle sound sources that use replaceable Sound Font (sf2) files, so you can play back input MIDI data even without an external sound source. ・Audio phrases can be played back while controlling the volume, effects, etc. using the Audio Mixer. [MIDI & Audio Editing] ・You can freely paste phrases (MIDI, Audio) anywhere on the 32 multi-tracks to create music. Supports inputting MIDI along with the wave, and recording voices and instrument performances along with MIDI. ・ MIDI phrases support an editor that allows event input and editing using the Grid screen, Event List screen, Rhythm screen, and Chord screen. The MIDI Control screen also supports event input during loop playback, and the import and editing of MIDI events by operating an external MIDI device. [Study and analysis of electronic instrument control and MIDI] ・Supports MIDI Router to control MIDI input and output. ・ It also supports a MIDI monitor function that allows you to visually check the contents of MIDI input messages. ・It supports a viewer/controller that allows you to visually check MIDI playback messages and output MIDI events by swiping. ・Equipped with message recording, editing, and playback functions newly supported by the MIDI 2.0 standard.

Verdict
The clearest difference is price: e at $1.99 against UK's $11.99. e also leads on iOS requirement (12.0 vs 17.6). UK's advantage is rating (5.0 vs 3.0) and in-app purchases (none vs 1). On ads, monetization model and device support there is nothing between them.
