Put the iPhone on your stomach. Breathe deeply. Enjoy... FOR ADVANCED BELLY-BREATHERS ONLY BellyBio (Belly Biofeedback) is a triple innovation in deep abdominal breathing, biofeedback and music: 1 – DEEP BREATHING GETS ADDICTIVE BellyBio generates beautiful music & light perfectly synchronized to your deep abdominal breathing movements, making deep breathing more pleasant and rewarding than ever. You're going to love playing with your inner balloon. 2 – BIOFEEDBACK GETS SIMPLE BellyBio turns your iPhone/iPod Touch into a highly-sensitive deep breathing sensor providing a real-time, objective stress-level index based on your breathing pattern. Biofeedback thus becomes more simple and powerful --not to mention affordable-- than ever, so you can now know for sure who's the coolest dude in the neighborhood. 3 – MUSIC GETS BREATHABLE The first "Abdominal Music Player", BellyBio makes music play in sync with your breathing, which in return makes your breathing calm down. Is it you who follow the music or the music that follows you? You don't listen to music anymore, you merge with it. IMPORTANT NOTICE -- Practicing BellyBio will require you to: a) BE ABLE TO NATURALLY BREATHE DEEPLY AND SLOWLY FROM YOUR BELLY, meaning your belly --and not your chest-- must significantly and effortlessly inflate when you inhale and deflate when you exhale. If you can't, you'd probably better not download this app since nothing is more annoying and ineffective than struggling to achieve deep abdominal breathing (and by the way this will perhaps avoid somewhat angry customer ratings... ;-)) b) PROPERLY POSITION THE iPHONE ON YOUR PELVIS, FACE UP, SO AS TO MAKE IT TILT BACK & FORTH when you breathe deeply in & out from your belly (BellyBio measures the increase/decrease of the angle between the iPhone and your body). The bottom of the iPhone should rest still on your pelvis while the top moves up and down with your lower belly as you breathe in & out. WATCH THE IN-APP DEMO to see how it works (www.youtube.com/bellybio). The app is quite heavy (170 Mo) due to the multiformat music base. Wifi is required to download it. ========== FEATURES - Several interactive musical themes you can breathe deeply in and out (i.e. have BellyBio play in sync with your deep abdominal breathing) - One of those themes (“Calmitude pitch”) provides you with a direct audio stress-level feedback through the pitch of the inhaling tone (the lower the stress, the lower the pitch) - Choice of breathing colors displayed in sync with each in- and out-breath - Graph showing real-time breathing and stress curves - Log (date, duration of use, minimum stress, minimum breathrate, Qi production) - 3D-earth animation showing all BellyBio users on the planet - Whether you have an iPhone or an iPod Touch, the main home button must always be close to your lap, not to your chest. - Child-proof (successfully tested on 5-year-old with adult assistance) QUOTES (sort of) - "All thumbs and navels up!!!" (Buddha, India) - "BellyBio rests on the belly just like the leaf floats on the sea." (Lao Tzu, China) - "Bellissimo BellyBio!" (L. Da Vinci, Italy) - "To breathe or not to breathe? To breathe, period. With BellyBio!" (W. Shakespeare, UK) - "I play BellyBio, therefore I stop thinking, therefore I am." (R. Descartes, France) - "So cool!" (I. Newton, UK) - "Makes me wanna compose a dozen sonatas and concertos for BellyBio! Please give me 10 minutes." (W. A. Mozart, Austria) - "Even with only one ear, this thing just blew my mind!" (V. Van Gogh, Netherlands) - "Undoubtedly absolute." (A. Einstein, Germany) - "Why didn't they call it iBelly?" (S. Jobs, USA) WARNING This application is not meant to substitute for medical diagnosis and/or treatment. Should you feel any pain or discomfort, please stop immediately and consult your physician or health professional.

The Mindfield eSense App turns your iPhone and iPad, together with the eSense Biofeedback sensors, into a comprehensive solution for stress measurement, relaxation training and self-awareness - in daily life, in training and coaching settings, and in research. **What is Biofeedback?** Biofeedback makes unconscious body signals such as skin conductance, skin temperature, pulse, breathing or muscle tension visible in real time. With targeted training you learn to influence these signals consciously - a scientifically well-documented approach for stress reduction and overall wellbeing. **Five sensors for precise biofeedback:** 1. **eSense Skin Response**: measures skin conductance (EDA, GSR) as a direct stress indicator. 2. **eSense Temperature**: captures skin temperature for effective hand-warming training. 3. **eSense Pulse**: Bluetooth chest strap for accurate heart rate and heart rate variability (HRV) measurement. 4. **eSense Respiration**: breathing-belt add-on for the eSense Skin Response - captures breathing rate, depth and pattern. 5. **eSense Muscle**: measures muscle activity (EMG) for targeted relaxation and activation training. **Comprehensive app features:** - **Customisable breathing pacer** with breathing rate, hold times and resonance breathing - **Multimedia feedback** through video, music, sounds, vibration and Philips Hue Smart Bulbs - **Adjustable training programs (procedures)** for structured multi-step sessions - **Unlimited archive** with ZIP export, CSV/PDF data analysis and per-sensor data wipe for shared devices - **Real-time thresholds** for reactive video feedback (sharpness, brightness, colour) - **14 languages**, continuous updates, intuitive operation **Concrete use cases:** - Stress management and more recovery in everyday life - HRV training and resonance breathing for autonomic balance - Breathing exercises for mindfulness, sports and mental clarity - Hand-warming training to support circulation - Muscle relaxation for desk-bound tension - Focus and performance training **Cloud functions and eSense Web App:** - **Basic Plan**: cloud storage of measurements and access to the eSense Web App (esense.live) - **Premium Plan**: additional cloud storage of procedures, real-time streaming to the Web App and sharing of measurements - **Web App**: simultaneous display of multiple sensors - ideal for group supervision and professional use **OSC and LSL streaming (In-App Purchase, optional):** For researchers and power users: stream your eSense data in real time directly from the app. - **OSC (Open Sound Control)**: to receivers like Max/MSP, Pure Data, TouchDesigner, Processing - **LSL (Lab Streaming Layer)**: to LabRecorder, OpenViBE, MATLAB, BCI2000, pylsl and other LSL-compatible research tools Both protocols are bundled into a single In-App Purchase. **Who is the app for?** - **Individuals** who want to train stress, breathing and relaxation in a focused way - **Trainers and coaches** for structured training sessions, with a multi-user-friendly archive on shared devices - **Researchers and universities** for quantitative data collection with bridges to MATLAB, LabRecorder and custom LSL pipelines **Flexibility and mobility:** - Use at home, in a training or coaching setting, or on the go with iPhone or iPad - Integration into daily life for regular biofeedback training - Free app with continuous updates and fair value for high-precision biofeedback hardware **More information:** - Product overview and tutorials: mindfield-esense.com - Order sensors and accessories: mindfield-shop.com - FAQ & support: help.mindfield.de With precise sensors, a versatile app and cloud functions, biofeedback integrates seamlessly into daily life, training and research.

Verdict
The clearest difference is rating: Mindfield eSense at 5.0 against BellyBio Interactive Breathing's 4.0. Mindfield eSense also leads on update cadence (every 3 weeks vs every 3 months). BellyBio Interactive Breathing's advantage is review sentiment (68% vs 45%) and ratings volume (41 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. BellyBio Interactive Breathing sells 4 one-off in-app purchases and Mindfield eSense sells 10 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Mindfield eSense holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: BellyBio Interactive Breathing has 41 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 68% of BellyBio Interactive Breathing's written reviews are positive against 45% of Mindfield eSense's, so the app with the better star average is not the one people write more warmly about.
BellyBio Interactive Breathing ships an update every 3 months, Mindfield eSense every 3 weeks. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
