The new experience brings Today's Snapshot, routines, Timeline, chat, wellness reports, nutrition, workouts, and mindfulness together in one app.
Onboarding became resumable, while Timeline gained search, filters, uploads, processing states, and health trackers. Privacy-filtered analytics were added to show where journeys needed improvement.
While recovering from his fourth knee surgery, Kalin Stoev began implementing a Personal Trainer inside xHeal's Workout App, initially building around what he needed himself. That personal starting point helped shape a workout experience designed around each person's recovery needs, current readiness, and path back to movement.
We are working with wellness clinics to bring xHeal into their programs. Their real-world expertise helps us improve xHeal, while personalized digital support helps clinics create a more connected experience for their guests.
Body, Mind, and Food appeared in one view, supported by reproducible routines based on pace, selected conditions, and enabled health areas.
xHeal gained meal logging and planning, readiness-aware workouts, guided breathing, mood check-ins, and activity history.
Interest in Doctor Ready and Health Gaps led to structured pilots with US physicians and participating xHeal users. Together, we began evaluating how xHeal could help people organize their health context before appointments and identify missing information for more prepared care conversations.
Apple Health history and live wellness indicators were connected with documents, reports, flare-up insights, and confirmable chat actions.
Profile details, goals, Health access, preferences, and account setup were brought into a single completion flow behind the scenes.
The team began a 12-week internal program while refining guided routine setup, daily tasks, completion feedback, and rewards.
xHeal reached its first 1,000 users outside alpha and beta testing. Their feedback helped the team redesign the experience and build the AI-based interface for v2.
xHeal became an AWS Partner and joined their startup credits program.
The first version goes live for American users.
During beta testing, an xHeal suggestion prompted Trifon to ask about insulin resistance and review additional lab results. His personal account became one of the team's early product stories, raising questions to explore with professional care.
The team explored ways to connect health information and evaluate model-generated explanations during the alpha period. This development milestone is not a clinical validation result for the current product.
xHeal was incorporated in Florida, USA.
Nikolay Nedyalkov joined as Co-Founder and CSO to help establish xHeal's presence in the United States and develop its commercial strategy.
Nikolay joined as Co-Founder and Head of AI, bringing machine-learning expertise to the team. Members of his family with medical backgrounds became advisors. The founding team was now complete.
Kris made the first commit to the xHeal v2 repository. The team set out to build a health companion that learns from the information people add, using a Digital Twin approach and aiming for a fully AI-powered backend.
Trifon shared his vision with Kris and Kalin. Both had gone through their own health struggles and instantly resonated with the idea. The founding team was born. A promise was made: No one should have to go through this alone.
Trifon describes four years of reading medical literature and investigating his symptoms. He says learning about dysbiosis, an imbalance in gut bacteria, was an important part of his recovery. This is his personal experience, not evidence that xHeal can identify a cause or produce the same outcome for others.
In 2019, at age 27, Trifon experienced recurring prostatitis, inflammation of the prostate. He describes feeling exhausted and uncertain after nine rounds of antibiotics and visits to doctors and specialists in Bulgaria and abroad. His search for an explanation led him to spend more time reviewing his health information.
