** World’s first AI hydration/water tracker app ** developed by Algomash Human face can give us hints, signs, reminders about health. What if an AI could estimate your hydration level just by looking at your selfie? That's what Bloom is all about. Bloom is not only water reminder but also water level estimator. Photo app estimating hydration of body from face photo. Bloom is a health, fitness selfie app. Gym workout, swimming, sports can make you dehydrated. Maintain hydration - that’s the motto. Even chess players have to hydrate to think, perform well by drinking fruit juices, milkshakes, water. Athletes tend to dehydrate. Muscle cramps are normal to athletes. Hydration tracking is left to human urge. In the age of AI apps, we wanted to build something that can change water tracking forever. Olympic athletes - boxers, swimmers, shooters, runners, tennis players, football players, fitness frenzies - all of them require proper hydration. AI running on device estimates hydration levels. The user takes a selfie. Face skin analysis estimates user’s hydration. Running on the Neural Engine on-device chip, it's lightning fast, providing the user results in a blink. Our algorithm is unique and achieves a high degree of accuracy. We are not going to stop here. We want to improve it and make it even better. We are hoping our users will provide feedback on the results to help us improve our AI to better serve users and our community. Some studies suggests blood glucose has connection with hydration. Dehydration can elevate blood glucose. Bloom now lets you take logs of blood glucose. Users can stay hydrated while take notice of sugar. Users can use an FDA approved blood glucose monitor to test their glucose and log that into Bloom. Logs are also added to Health app. Disclaimer: The Bloom app should not be considered a medical device and is not FDA approved. If you have symptoms of severe dehydration, please seek immediate medical attention. Do not rely on Bloom estimates. We do not guarantee the results. We advise our users not to change their water intake based on Bloom's estimate alone. We care for our users and their good health is our priority.
