Aqua Carpatica is the only mineral water in the world that has no nitrates in the composition. To emphasize this quality that very few are aware Aqua Scanner allows users to scan the label of the mineral water bottle and compare the results with Aqua Carpatica. The results are including other useful values as Sodium, Calcium, Magnesium, PH and HCO3. The technical challenge was to implement a scanning solution that works very well on different type of bottle labels. The CMS allows updates with new mineral waters with no need of updating the app.
