Inspiration

Dogs show internal stress and health signals long before humans notice them. Changes in heart rate, body temperature, and movement patterns often reveal early signs of sickness — signals invisible to the human eye. Many owners discover something is wrong only when it’s already serious, and sometimes too late to act. Tailysis was created to detect these early internal signals and reveal what dogs feel before visible symptoms appear.

What it does

Tailysis is a biometric dog collar that tracks key physiological indicators and converts them into simple emotional and health insights. Measures: -heart rate -body temperature -movement patterns Identifies: -stress or anxiety -overstimulation -excitement -calm/rest -discomfort -early overheating -early sickness warning signs that owners normally cannot see App features: -real-time emotional & health indicators -clear, simple insights instead of complex graphs -gives owners a chance to act early and protect their dog’s wellbeing

How we built it

Hardware: -Custom-built using separate components: MAX30100 (heart rate), DS18B20 (temperature), MPU6050 (motion), Arduino Uno R3. -Hand-wired, tested, and assembled into a wearable collar system. Firmware: -Structure drafted with Anigravity AI. -Fully refined in Arduino IDE: optimized sampling, noise filtering, timing, and data formatting. App: -Developed in Natively. -Receives Bluetooth data and translates it into readable emotional states. Website: -Built using Lovable to present the product and gather early sign-ups.

Challenges we ran into

Building Tailysis was anything but smooth. When one sensor worked, another failed. When the hardware behaved, the app broke. If the firmware compiled, Bluetooth stopped responding. Choosing the right app tools took longer than expected, and coding issues followed us everywhere—connection drops, formatting errors, UI bugs, and unstable readings. The website’s admin page also took far more time than planned. Managing hardware, firmware, app, algorithm, and website development at the same time stretched our time and focus. There were moments when nothing aligned… But after countless late-night fixes, rewires, and debugging cycles, everything finally connected and worked as one system. Every setback made Tailysis better—and made the final success worth it.

Accomplishments that we're proud of

Despite the challenges, we achieved far more than we expected. Our full prototype works end-to-end — the sensors read data, the firmware processes it, the app displays it, and everything communicates in real time. We managed to solve our coding issues under pressure and get every part of the system functioning before the deadline. We also launched a clean, professional website to present the project and gather early interest. But our biggest accomplishment wasn’t the hardware or the software — it was the teamwork behind it. We supported each other, divided tasks, stepped in when someone got stuck, and pushed through late nights together. Tailysis exists today because we built it as a team, not as individuals. This combination of technical progress and strong collaboration is what makes us most proud.

What we learned

This project forced us to learn faster than ever. We used many tools for the first time — hardware sensors, app builders, and AI-assisted coding — and had to figure everything out on the go. Some teammates started with little coding experience, so writing firmware, fixing errors, and building the app pushed us to develop real skills quickly. We learned to adapt fast when things broke, stay flexible, and find solutions under pressure. Managing hardware, software, design, and testing at the same time taught us to prioritize, communicate, and stay organized. Above all, we learned to work as one team — supporting each other, stepping in when someone struggled, and solving problems together. Tailysis taught us not just new tech, but how to learn, adapt, and collaborate at high speed.

What's next for Tailysis

Our next step is to finish the full prototype and move from testing hardware modules to integrating the entire system into a real, durable dog collar. Once the final electronics and form factor are complete, we plan to begin sourcing reliable suppliers and manufacturing partners. We will launch Tailysis first in Lithuania, where we’ll gather real user feedback from dog owners, trainers, and veterinarians. After validating the product and refining the design, we aim to expand across the Baltic states. Once Tailysis reaches a polished, stable, market-ready version, our long-term goal is to enter the US market, where demand for pet-tech and wellbeing products is rapidly growing. Tailysis is only at the beginning — and we’re excited for the next stages of building it into a fully developed consumer product. shorten this text and add bullet point so it would be esier to read
