Samsung Hearapy vs RideCalm vs Sense Relief: Comparing Motion Sickness Apps in 2026

What Is Samsung Hearapy?

In March 2026, Samsung launched Hearapy as a feature within Samsung Health on Galaxy devices. Hearapy plays a specific 100Hz sound frequency through Galaxy Buds earbuds to help reduce motion sickness symptoms like nausea, dizziness, and cold sweats during travel.

The feature made headlines because it offered a genuinely novel approach to an age-old problem. Instead of pills, patches, or wristbands, Hearapy uses sound therapy to directly interact with the vestibular system -- the part of your inner ear responsible for balance and spatial orientation.

Samsung did not invent this approach from scratch. The technology is grounded in real academic research that predates Hearapy by several years. That research is what makes both Hearapy and RideCalm possible.

The Nagoya University Research Behind Both Apps

The foundation for 100Hz sound therapy comes from a study conducted by researchers at Nagoya University in Japan, published in the journal Environmental Health and Preventive Medicine in March 2025.

The study involved 82 participants across three different motion scenarios: a controlled swing, a driving simulator, and a real vehicle. Researchers found that exposing participants to a 100Hz pure tone for just 60 seconds significantly reduced motion sickness symptoms compared to control groups.

The mechanism works through the otolith organs -- specifically the utricle and saccule in the inner ear. These tiny structures contain calcium carbonate crystals that respond to linear acceleration and gravity. The 100Hz vibration stimulates these organs, helping the brain reconcile conflicting signals from the eyes and vestibular system.

"The 100Hz frequency was selected because it resonates optimally with the otolith organs, providing vestibular stimulation that reduces the sensory conflict responsible for motion sickness." -- Nagoya University research team

The key finding: a brief 60-second exposure could provide symptom reduction lasting up to 2 hours. This is what both Samsung Hearapy and RideCalm are built upon.

How RideCalm Brings the Same Science to iPhone

Samsung Hearapy is exclusive to Galaxy devices and optimized specifically for Galaxy Buds. If you own an iPhone -- or prefer using AirPods, Sony, Bose, or any other headphones -- Hearapy simply is not an option for you.

That is where RideCalm comes in. RideCalm implements the same 100Hz pure tone protocol from the Nagoya University research, but it is designed specifically for iOS and works with any headphones you already own.

The app generates a precise 100Hz sine wave using the device's audio engine. You put on your headphones, tap play, listen for 60 seconds, and then enjoy reduced motion sickness symptoms for up to 2 hours. It is the same science, the same frequency, and the same protocol -- just available to everyone, not only Samsung Galaxy users.

The Third Player: Sense Relief

While Samsung Hearapy and RideCalm both use 100Hz sound therapy rooted in vestibular neuroscience, a third app takes a completely different approach. Sense Relief is an Apple Watch app that uses acupressure vibration on the P6 (Nei-Guan) wrist point to reduce nausea during travel.

The technology behind Sense Relief is based on Traditional Chinese Medicine rather than modern vestibular research. The app vibrates the inner wrist at specific intervals, targeting the same pressure point used by anti-nausea wristbands like Sea-Bands. The idea is that stimulating this point sends signals through the median nerve that can reduce feelings of nausea.

There is an important hardware requirement: Sense Relief runs exclusively on Apple Watch and requires an Apple Watch ($249+) to function. It does not work on iPhone alone. The app uses the Watch's haptic motor to deliver the acupressure vibration, which means it is always on your wrist during a trip -- no headphones needed, but also no option to use it without the Watch.

Based on publicly available App Store data, Sense Relief currently holds a 3.4 out of 5 rating with 38 ratings. According to user reviews, the most common complaints include crashes on startup, being locked out after account login issues, and confusion about whether the app works on iPhone without an Apple Watch. Several reviews also mention that the app's "auto mode" can interfere with Apple Watch exercise tracking data. The app appears to have last been updated over a year ago, which raises questions about ongoing maintenance and compatibility with newer watchOS versions.

It is worth noting that some users do report positive experiences with Sense Relief, particularly for motion sickness and even morning sickness. The app is listed in the Medical category on the App Store, which subjects it to higher scrutiny from Apple's review team compared to Health & Fitness apps.

The key distinction between Sense Relief and the sound therapy apps is the underlying science. Sound therapy was specifically designed and tested for motion sickness through controlled studies. Acupressure for motion sickness has a longer history in traditional medicine, but the clinical evidence supporting it for this specific use case is more limited, as we explore further below.

Feature-by-Feature Comparison

Here is how all three apps stack up across the features that matter most for travelers:

Which Approach Has the Strongest Research?

When comparing these three apps, the underlying evidence matters. 100Hz sound therapy (used by both RideCalm and Samsung Hearapy) is backed by a peer-reviewed study from Nagoya University published in Environmental Health and Preventive Medicine. The study tested 82 participants across three controlled motion scenarios -- a swing, a driving simulator, and a real vehicle -- and found statistically significant reductions in motion sickness symptoms from a 60-second exposure to 100Hz sound.

P6 acupressure vibration (used by Sense Relief) draws from Traditional Chinese Medicine and has been studied more broadly for nausea in general. However, a 2004 Cochrane systematic review -- one of the most rigorous forms of medical evidence analysis -- examined the available trials and concluded there was "no reliable evidence" that P6 acupressure point stimulation prevents motion sickness specifically. The review did note more promising evidence for postoperative nausea and pregnancy-related nausea, but the motion sickness evidence remained inconclusive.

The key distinction: 100Hz sound therapy was specifically designed, tested, and validated for motion sickness through a modern controlled study. Acupressure has a longer history in traditional medicine and may help some individuals, but the scientific evidence for its effectiveness against motion sickness specifically is weaker. Both RideCalm and Samsung Hearapy benefit from this more targeted research foundation.

Why Sound Therapy Is the Future of Motion Sickness Relief

For decades, the go-to options for motion sickness have been medications like Dramamine (which causes drowsiness), scopolamine patches (which require a prescription and have side effects), and acupressure wristbands (which have limited evidence supporting them).

Sound therapy represents a fundamentally different approach. Here is why it stands out:

• No medication side effects. Unlike antihistamines that cause drowsiness, sound therapy has no known adverse effects. You stay alert and clearheaded.
• Rapid onset. Medications often need 30-60 minutes to take effect. Sound therapy works in 60 seconds.
• Non-invasive. No patches, no pills, no injections. Just put on your headphones.
• Addresses the root cause. Rather than masking symptoms, 100Hz stimulation works directly on the vestibular system to reduce the sensory conflict that causes motion sickness.
• Always available. Your headphones are already in your pocket. No need to plan ahead, visit a pharmacy, or carry extra supplies.

Samsung bringing Hearapy to Galaxy devices was a strong signal that major technology companies see merit in this approach. It validated years of academic research and opened the door for broader adoption. RideCalm ensures that this breakthrough is not limited to a single ecosystem -- it brings the same research-backed approach to the hundreds of millions of iPhone users worldwide.

Which Should You Choose?

The answer depends on what devices you own and which approach you prefer. If you use a Samsung Galaxy phone with Galaxy Buds, Hearapy is a convenient built-in option. If you use an iPhone -- or if you want to use your own preferred headphones with any device -- RideCalm is your best option for research-backed sound therapy.

If you already own an Apple Watch and are curious about acupressure-based relief, Sense Relief offers a different approach -- though based on user reviews, you may encounter stability issues and the scientific evidence for this method against motion sickness is more limited.

RideCalm offers features that neither competitor provides: a 2-hour relief countdown timer so you know exactly when to re-play, a detailed trip log for tracking different travel scenarios, a feeling tracker to monitor your response over time, and complete session history with statistics.

RideCalm and Samsung Hearapy are both built on the same Nagoya University research and use the same 100Hz frequency. The difference is accessibility and the experience around it. RideCalm was designed from the ground up as a dedicated motion sickness relief app, not an add-on feature inside a general health platform -- and it works with any headphones you already own.
