eSense App

eSense app from Mindfield

We recommend our eSense app with extended features for free in the Google Play Store (Android) and in the Apple App Store (iOS)

The eSense App is for the eSense Skin Response, eSense Temperature, eSense Pulse and eSense Respiration and eSense Muscle. It is available in 14 languages.

New in version 8.1.6 (August 2026)

Automatic restart of a measurement: when the timer stops the measurement, it starts again on its own, up to five times in a row. Every run is stored as its own recording.
After an update the app shows what is new and reports newer versions in the store.
eSense Skin Response: SCR counting now follows an amplitude criterion of 0.02 µS with a rise time of 1 to 20 seconds. Recordings from before and after the update are not directly comparable in this figure. We explain the background in the help desk.
Procedures with your own images, videos or audio files work reliably again.

Earlier releases added reliable detection of USB audio adapters on iOS, settings stored per sensor, Philips Hue support over Bluetooth without a bridge, streaming via OSC and LSL, and extended smart bulb features in procedures and open training. The full list per version is in the changelog.

With this app you can…

…do biofeedback training
…measurize and reduce your stress level
…create and use a guide for meditation
…run predefined procedures or build your own
…analyse measurements as CSV or PDF and back up the archive as a ZIP file
…delete data per sensor when several people share the same device
…stream measurements in real time via OSC or LSL to research software (in-app purchase)

eSense app from Mindfield

The eSense comes with the eSense app which you can load for free in the in the Google Play Store (Android), in the Apple App Store (iOS) or the Amazon Appstore. The app contains a variety of functions for an effective biofeedback training in a modern design. Essential function are the display of the measured values app as bargraph and oscilloscope, a feedback by video, music, tones, vibration and by light via a Bluetooth® smart bulb.

Free App

The price of the eSense includes in parts the hardware and also the software (the eSense app) all in once. We spend huge amounts of money for the programming and continuous development of the app. However, the eSense app is available for free in the App Stores. Our customers should not pay twice at different locations and, moreover, it is unusual for most people to pay a larger sum for an app. The eSense offers unbeatable value for your money and is a unique, high-precision biofeedback device with many features.

Which iOS Devices are Supported?

All iOS devices from version 15 or higher, including (in part):
Apple® iPhone® SE (all generations), iPhone® 8/8+, iPhone® X, iPhone® XR, iPhone® XS, iPhone® 11, iPhone® 12, iPhone® 13, iPhone® 14, iPhone® 15, iPhone® 16 and iPhone® 17, each including the Plus, Pro and Pro Max variants
Apple® iPad® 5th generation or newer, including all iPad Mini from 4th generation and iPad Air from 2nd generation or newer
Apple® iPad® Pro from 1st generation or newer
Note: Some newer iOS devices without the classic 3.5mm headphone jack and with the newer Lightning / USB-C connector also work perfectly with the eSense. You either need an original Apple USB-C or original Apple Lightning to 3.5 mm connection adapter (not included in the scope of delivery of the eSense). Alternatively you also can use any other adapter with a DAC chip. We recommend this adapter on Amazon

Which Android Devices are Supported?

All Android Smartphones and Tablets from Android 10.0 (Android Q)
Your Android device requires a 3,5mm jack (headphone jack) for external microphones for the eSense Skin Resonse, Temperature and Respiration. Your Android device requires Bluetooth® for the eSense Pulse.
If you plan on purchasing a device for using the eSense, we suggest a Nokia G10, a Nokia G21, a Motorola Moto E40 or a Xiaomi Redmi 10 as an inexpensive entry-level device.

Procedures

A Procedure consists of several assembled modules. A module can be for example a picture, a video, some music, a bargraph, an arrow or others. You can assemble the modules in any length to a fixed procedure. Some contain biofeedback-functions (that means they reflect the changes in your measured values from the eSense), some don’t.

With this feature you can build the perfect individual relaxation guide, a stress test, a predefined biofeedback training or use it for your own research. There are many possibilities. During a procedure, your skin response, respectively or temperature (depending on the eSense sensor you have) will be recorded. Afterwards you see your results for each module and in total and you can export those to Excel for further analysis.

Breath Pacer

There is a breathing aid in our app. You can follow various animations by working with your breath. The special thing about it is that breathing is the only bodily value that we can consciously control. This means there are many ways to make your biofeedback training varied and effective.

Breathing rate and hold times can be set freely. For resonance breathing, where breathing and heart rhythm are aligned, you can match the pacer to your personal rhythm.

Account und Cloud (optional)

You can register your own account for the eSense app and book plans. With these you can mainly use the cloud and its functions and get also access to the eSense web app at www.esense.live.

With the basic plan, you can save your measurements locally and online in the cloud and thus access your measurements from all devices and from anywhere. You also get access to the eSense web app

The Premium Plan includes all functions of the Basis Plan. In addition to your measurements, you can also save your procedures online in the cloud and thus access your procedures from all devices. (Attention: Technical limitations from Apple unfortunately do not allow the upload (and thus the synchronization) of audio files. The synchronization of picture and video files is possible, however). You can buy the Premium Plan here: https://mindfield-shop.com/en/product/premium-plan-for-esense-app-for-all-esense-sensors-annually/

You can also share your measurements with other users. You also have the option to transfer your data to the eSense Web App in real time.

Smart bulbs (optional)

The app supports Philips Hue and Magic Blue smart bulbs. Philips Hue bulbs connect directly over Bluetooth, so a bridge is no longer required.

The Magic Blue is a smart bulb which can be controlled via Bluetooth®. The color as well as the brightness can be adjusted. This enables you to use the light from the bulb as an indicator of your level of stress or relaxation in combination with the eSense Skin Response or eSense Temperature.

From within the eSense App, you can connect to the Magic Blue and use it in your biofeedback session. Depending on the state of your relaxation, the bulb can show different colors or a different brightness or a combination of both

Data streaming for research (optional)

Measurements can be passed on from the app in real time. Two established protocols are available:

OSC (Open Sound Control) for receivers such as Max/MSP, Pure Data, TouchDesigner or Processing.
LSL (Lab Streaming Layer) for LabRecorder, OpenViBE, MATLAB, BCI2000, pylsl and other LSL-capable tools.

Both protocols are covered by a single in-app purchase, which makes the app suitable for quantitative data collection in studies and teaching.
