New updated iOS app - "Magnetscape" version 8.0

"Magnetscape" has been updated to version 8.0 now!

The latest version is compatible with iOS 26.1, optimized internal processing and improved stability.

"Magnetscape" is a new real-time measurement app that observes invisible magnetic fields using the iPhone's built-in magnetic sensor.

There are various magnetic fields around us. For instance, the magnetic field fluctuates even when large motors, compressors or metal are nearby. The Earth's magnetic field exists even in empty places, and we are constantly affected by it.

"Magnetscape" enables real-time monitoring of surrounding magnetic fields and can be utilized for various applications in real life. It can be used for investigating static magnetic fields, searching weak electromagnetic fields within alternating magnetic fields, locating metals and more.

This app features three measurement modes for magnetic field observation, allowing you to use it according to your needs.

- Scope


The magnetic field strength (unit: uT) is displayed numerically, along with a graphical representation (level circles) showing the magnitude and direction of the magnetic field.

- Time


Displays the time transition of raw data from the magnetic sensor and the sensor-corrected data.

- FFT


Perform frequency analysis using FFT on the fluctuating magnetic field. Additionally, by displaying peak levels in hold mode, you can observe the maximum values of each frequency component.

New updated iOS app - "Vibroscope" version 10.0

"Vibroscope" has been updated to version 10.0 now!

The latest version supports iOS 26.1, optimized internal processing, and improved stability.

Vibroscope is a vibration measurement and analysis app that utilizes the iPhone's accelerometer.

This app visualizes and monitors low-frequency vibrations inaudible to the human ear.

It graphically displays the horizontal direction as a two-axis vector and the vertical direction as a time-axis waveform, allowing you to intuitively check vibration levels (acceleration: m/s²).

# Application Examples
- Analysis and evaluation of ride comfort and driving operation for automobiles, trains, etc.
- Analysis and evaluation of vibrations caused by vehicle traffic, factory noise, etc. (acceleration on floors/walls, frequency components)
- Vibration measurement for phenomena like audio equipment feedback (howling)
- Measurement of vibration acceleration from earthquakes, etc.
- Balance sense testing via body sway detection

# Main Mode: Vibration Analysis Graph (Instantaneous Acceleration) Linear Display



The app automatically detects horizontal and vertical orientations regardless of the iPhone's position, enabling use on surfaces like tables or desks, as well as handheld operation. You can also switch the axis direction of the graph display during measurement.





# Main Mode: Vibration Analysis Graph (Instantaneous Acceleration) Logarithmic Scale Display



# Main Mode: Vibration Analysis Graph (Average Acceleration)



Additionally, it features an FFT analyzer for analyzing the frequency components of low-frequency vibrations. This can also be used to investigate the characteristics of vibration sources.

New updated iOS app - "Reverb Time Analyzer" version 3.0

"Reverb Time Analyzer" has beem updated to version 3.0 now!

The latest version supports iOS 26.1, optimized internal processing, and improved stability.

"Reverb Time Analyzer" is an acoustic analysis tool for iPhone that allows you to measure the reverberation time of a room.

Would you like to control the sound reverberation in your listening room? Knowing the reverberation time is one of the guidelines for creating a comfortable sound space. For example, it can be obtained as objective data on the current status of various acoustic disturbances, such as high room reverberation and poor intelligibility, too much flutter echo and howling.

This app can analyze the reverberation time using the interrupted noise method, in which a random test noise signal is generated from the iPhone's speaker and then turned off. Up to 6 consecutive measurements, reverberation time analysis, and spectrogram analysis can be performed.



After measurement completion, reverberation time analysis is performed, displaying the reverberation time (RT30, RT60) results alongside the reverberation decay curve. Note that this app uses RT30, the time required for a 30dB attenuation, for measurement and converts it to RT60 by doubling the RT30 value.

The following analysis results (Avg) are based on averaging the results from six measurements. Individual measurement results can also be displayed.　　　　



Spectrogram analysis of measurement signals is also possible, displaying spectrograms in 1/3 or 1/48 octave bands. When reverberation time is relatively long, the reverberation distribution across each frequency band can be observed.

New updated iOS app - "Sound Level & Spectrogram" ver 3.0 - Free of charge!

"Sound Level & Spectrogram" has been updated to version 3.0 today!

Measure noise and music accurately with your iPhone. Visualize your sound environment with this genuine dB meter app. This app is completely free of charge!

"Sound Level & Spectrogram" is a sound level meter app for iPhone to easily measure the sound level of noise and music in your living environment.

Latest version includes internal processing improvements and compatibility with iOS 26.

Simply tap the start button to measure sound levels in decibels (dB) and view the real-time variation of the sound level.



You can also use the spectrogram feature to visually check the frequency characteristics of the sound source.



Exposure to noise can impact health, potentially causing tinnitus, sleep disorders, stress, cognitive decline and heart disease. These risks have also been highlighted by the World Health Organization (WHO).

Understanding noise levels is the first step towards improving your quality of life. Use this app to protect your health and create a comfortable living environment.

The WHO has published guidelines on the health risks of noise, which are presented here as reference information for noise management.

# Noise levels and allowable exposure times
100 dB : just a few minutes/day (weekly limit 20 minutes)
95 dB : 10 minutes/day (weekly limit 1 hour 15 minutes)
90 dB : 30 minutes/day (weekly limit 4 hours)
85 dB : 1 hour 45 minutes/day (weekly limit 12.5 hours)
80 dB : 5 1/2 hours/day (weekly limit 40 hours)

In general, quality of life begins to be affected at noise levels above 60 dB, and the risk of health problems increases at levels above 80 dB. Prolonged exposure to high levels of noise can cause temporary hearing loss.

New updated iOS app - "Sound Level & Spectrogram" ver 2.1 - Free of charge!

"Sound Level & Spectrogram" has been updated to version 2.1 now!

"Sound Level & Spectrogram" is a sound level meter app for iPhone that can easily measure the sound level of noise and music in your living space.

Check if the noise level is appropriate with this app and protect your health and comfortable life.

In the latest version, we have improved the internal processing and updated the icon design.

This app can measure the sound level (noise level) in real time by simply pressing the start button. You can switch between frequency weighting characteristics (A / C /Z) and time weighting characteristics (FAST / SLOW), which are essential for general sound level meters, for proper sound level measurement. Sound levels are displayed in decibels (dB).



A time course graph of sound levels and frequency analysis with spectrograms provide a visual confirmation of the characteristics of the sound source.



The World Health Organization (WHO) has noted a direct correlation between noise and health risks. It can cause a variety of health risks, including tinnitus, sleep disturbances, stress, cognitive impairment, and heart disease.

The WHO has published guidelines on the health risks of noise, which are presented here as reference information for noise management.
