Key Takeaways
Company: Pulsetto, a non-invasive neck-worn vagus nerve stimulation device, helps users manage stress, improve sleep, and enhance overall well-being.
Challenge: Integrating multiple wearable platforms (Apple Health, Oura, Garmin, Whoop, Fitbit, and more) would require months of development and ongoing maintenance, creating a distraction from Pulsetto’s core innovation.
Solution: Integrated Spike Wearables API to enable automatic health data syncing from wearable and IoT devices through a single unified integration, replacing the need for custom platform-specific development.
Results:
- Tens of thousands of wearable integrations across 12 major providers
- Months of development time saved by using Spike unified Wearables API
- Low maintenance as Spike handles all API updates
- Users can track vitals before and after using Pulsetto
- Users can measure long-term impact on HR, HRV, sleep, and recovery
Learn how Pulsetto enhanced their platform by connecting their users’ wearable devices through the Spike Wearables API.
Pulsetto is a non-invasive neck-worn vagus nerve stimulation device intended to help manage stress and anxiety and improve sleep and overall well-being.
Pulsetto's mission is to empower its users to take control of their stress levels by providing real-time biometric feedback. The Pulsetto app is designed to make stress management accessible, personalized, and data-driven.
By integrating wearable data, Pulsetto enabled its users to track how vagus nerve stimulation sessions impact their overall well-being. The vagus nerve is the master regulator of the parasympathetic nervous system, and connecting Pulsetto with wearables data lets users check their vitals immediately after a session to see changes in heart rate (HR), and track longer-term improvements in heart rate variability (HRV), sleep quality, and recovery. This innovation sets Pulsetto as the leader in the vagus nerve stimulation market.
"Spike enabled us to support the wearables our users already have. We can focus on perfecting our vagus nerve stimulation technology while Spike handles the complexity of health data integration", says Povilas Sabaliauskas, CEO of Pulsetto.
The Challenge
Pulsetto helps users manage stress through vagus nerve stimulation technology. To provide holistic wellness insights on top of their own device data, they needed to combine their proprietary stress metrics with biometric data from the wearables and health platforms that their users already use daily, to enable them to see how each stimulation session affects their vitals and track progress over time.
The problem? Building these integrations themselves would significantly derail the product roadmap.
"Our users already track their health with Apple Watch, Oura Ring, Garmin, and other devices," explains Povilas. "They expect to see how our vagus nerve stimulation affects their sleep, HRV, and recovery. Building individual integrations for each platform would have been a massive engineering undertaking."
The challenge was to access and integrate data from multiple major platforms, including Apple Health, Health Connect, Oura, Garmin, and Whoop. Each platform has its own API, authentication flow, and data structure, hence requiring custom integration and months of development.
Beyond the initial build, ongoing maintenance posed another hurdle. When providers update their APIs, someone has to drop everything to fix broken integrations. For a fast-growing healthtech company leading innovation in vagus nerve stimulation technology, this maintenance burden would be unsustainable.
Why Spike API
Spike Wearables API provided Pulsetto with a unified, plug-and-play solution for integrating wearable and IoT devices with no custom infrastructure required.
“Spike allowed us to launch wide wearable support in a fraction of the time. Their team was incredibly responsive, guiding us through implementation and helping us fine-tune the user experience,” highlighted Povilas. “The fact that Spike maintains every integration and handles provider API changes means our engineers stay focused on building better stress-management features, not fixing external integrations.”
Key implementation features:
- Unified data model: Normalized biometric data across all platforms
- Seamless authentication: Built-in OAuth flows handling user authorization
- Real-time synchronization: Automatic data updates ensure users see their latest metrics instantly
- Maintenance-free operation: Spike handles all provider API updates
Results
Pulsetto achieved tens of thousands of wearable integrations across 12 major providers after implementing the Spike Wearables API, with clear trends emerging:
Platform leaders:
- iOS (47.9%) and Android (17.5%) are showing balanced platform distribution
- The adoption of premium wearables, such as Oura, is demonstrating strong appeal to wellness-focused users, which is the target audience of Pulsetto.
Fitness & activity trackers:
- Major fitness platforms, such as Garmin, Whoop, and Fitbit, exhibit significant user adoption
Medical devices:
- Connected IoT devices are expanding the health data ecosystem
The numbers keep growing, showcasing the impact wearable integration drives.
Business Impact
- Accelerated development: Spike eliminated months of engineering work required to build and maintain multiple integrations.
- Low maintenance: Provider API changes are handled entirely by Spike.
- Premium user appeal: High adoption of Oura (15.3%) and Whoop (5.3%) signals strong resonance with wellness-focused consumers, Pulsetto’s ideal demographic.
- Platform universality: Strong performance across both iOS and Android ecosystems.
- Enhanced user experience: Users can now measure the immediate impact of each vagus nerve stimulation session on their heart rate and track long-term improvements in HRV, sleep quality, and recovery, providing measurable proof of progress and increasing user engagement with the Pulsetto device.
- Focus on core innovation: With integration complexity removed, Pulsetto’s engineering team dedicates its time to enhancing vagus nerve stimulation technology and stress insights.
“Spike doesn’t just provide an API; they provide peace of mind. Their support team was always there, responding quickly and helping us optimize our integration. It felt like having an extension of our own engineering team,” Povilas Sabaliauskas, CEO of Pulsetto.
Looking Forward
As Pulsetto continues to scale, its partnership with Spike positions it as a leader in the data-driven stress management and vagus nerve stimulation technology landscape. By integrating insights from wearables users already have, Pulsetto delivers a holistic wellness experience that sets it apart in the competitive healthtech space.
Spike takes care of integration maintenance, allowing the Pulsetto team to stay laser-focused on advancing vagus nerve stimulation technology and helping users manage stress.
