Kelda
Connect your meds, labs, symptoms and wearable data to how you actually feel.
About
Kelda is a modern, AI-powered health companion designed to help people understand the deeper connections between their medications, lab results, symptoms, and daily well-being. Presented through Kelda, the platform addresses a common frustration in healthcare: patients often go through multiple tests and consultations, only to be told that everything is “within range,” while still feeling unwell. Kelda positions itself as the missing layer between raw medical data and real-life experience, offering insights that traditional healthcare systems may overlook.
At its core, Kelda works by cross-referencing multiple sources of personal health data. Users can input their medications, upload lab results, track symptoms, and even connect wearable devices such as fitness trackers. The system then analyzes this information to detect patterns, interactions, and potential nutrient depletions that could explain how a person feels. For example, it may identify that a commonly prescribed medication is lowering magnesium levels, which in turn could be linked to fatigue, poor sleep, or muscle cramps. It also goes beyond standard lab interpretations by highlighting what is “optimal,” not just what falls within a general reference range.
One of Kelda’s most compelling features is its ability to uncover hidden patterns over time. Instead of viewing health data as isolated snapshots, the platform continuously monitors changes and correlations. This means it can detect shifts in sleep, energy, or mood that coincide with medication changes or evolving health conditions. By doing so, Kelda provides users with a clearer, more connected understanding of their health journey—something that is often difficult to achieve through occasional doctor visits alone.
The platform supports a wide range of conditions and health concerns, from common issues like iron deficiency and hormonal imbalances to more complex patterns involving autoimmune disorders, gut health, and metabolic dysfunctions. It also identifies advanced biochemical interactions, such as enzyme inhibition or nutrient imbalances, offering a level of analysis that feels both comprehensive and personalized. Despite this depth, Kelda maintains a user-friendly approach, presenting insights in a way that is easy to understand and actionable.
Another important aspect of Kelda is its role as a support tool rather than a replacement for medical professionals. The platform emphasizes that its insights are educational and meant to empower users to have more informed conversations with their doctors. By walking into appointments with clear data-driven observations and targeted questions, users can make better use of their limited time with healthcare providers.
Real-world testimonials further reinforce Kelda’s value, showcasing how individuals have discovered overlooked connections that led to meaningful improvements in their health. From long-standing unexplained symptoms to subtle nutrient deficiencies, the platform has helped users uncover answers that traditional approaches missed.
In essence, Kelda transforms scattered health information into a coherent narrative. It bridges the gap between clinical data and personal experience, helping users understand not just what is happening in their bodies, but why. By combining continuous tracking, intelligent analysis, and practical insights, Kelda empowers individuals to take a more active and informed role in their health, making it a powerful tool in the evolving landscape of personalized healthcare.

I used to text every single paying customer for 6 months asking for feedback i just add "Hey I'm Dennis the founder of Yadafone i would be thrilled to know what you think about the app and how your experience was so far."
Text Every Paying Customer Personally for Six Months to Catch Problems
Dennis sent personal messages to every paying customer over his first six months, using the responses to understand which user segments were being served best and to surface complaints before they turned into public bad reviews. He acknowledges the approach is time-consuming and draining, but credits it with shaping the product's direction and keeping churn low.
my biggest regret is not the $40 a year is that I didn't do a sale on launch... all that attention I did get most of the people who wrote about it listed the price and a lot of people... saw $40 and were like no way but if they had seen $40 but 50% off I think we would have done better.
Run a Launch Sale: Attention Without a Price Incentive Converts at a Fraction of the Rate
The press exposure was real: TechCrunch, 9to5Mac, MacRumors, Boy Genius Report. But everyone listed the $40/year price, and readers who might have subscribed with a discount impulse-purchased nothing instead. For any attention-grab launch, combining the moment with a time-limited offer (25-50% off) is the missing multiplier — it creates urgency where curiosity alone produces bookmarks.
There's a play for whatever you're stuck on.
