Complete mineral composition analysis for 69 bottled water brands. Compare pH levels, minerals, and safety grades to make the right choice for your health.
About
Water Quality provides a complete mineral composition analysis for 69 bottled water brands available in Europe and worldwide. Every brand profile includes detailed breakdowns of calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, and fluoride concentrations — giving you a full picture of what you're drinking with every sip.
The app compares mineral levels against recommended daily intake values and highlights where each brand excels or falls short. Whether you're an athlete looking for electrolyte-rich water, someone on a low-sodium diet, or a parent seeking safe water for baby formula preparation, Water Quality helps you make an informed choice.
The full comparison feature lets you evaluate multiple brands side by side. Sort and filter by individual minerals, pH level, or overall quality grade to find the perfect water for your lifestyle and health needs.
Features
From mineral breakdowns to safety grades — every detail about the water you drink.
Comprehensive database covering 69 bottled water brands from across Europe and worldwide, with full mineral profiles from official analyses.
Detailed breakdown of eight key minerals — calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, and fluoride — with daily intake percentages.
Every brand is evaluated for pH level against the optimal 6.5–8.5 drinking water range, with clear safety indicators and health context.
Place two or more water brands side by side and compare complete mineral profiles, pH levels, and quality grades.
Specialized safety assessment for parents preparing baby formula, checking sodium, nitrate, and fluoride levels against pediatric safety thresholds.
Full app interface in German, English, Spanish, French, Italian, Dutch, Portuguese, and Romanian — for users across Europe and beyond.

Data
Water Quality is powered by an internal database compiled from official water brand mineral analyses, laboratory certifications, and European water quality standards. Each brand's mineral profile is sourced directly from manufacturer-published composition data and cross-referenced with independent laboratory results where available.
Safety thresholds and quality benchmarks are derived from guidelines established by the World Health Organization (WHO), the European Union Drinking Water Directive, and national food safety authorities. Baby formula safety criteria follow pediatric nutrition guidelines from ESPGHAN.
Grading
How Water Quality calculates a comprehensive safety grade for each brand.
Excellent — Optimal mineral balance, pH within ideal range (6.5–8.5), very low sodium. Suitable for all consumers including infants.
Good — Strong mineral profile with minor imbalances. pH within acceptable range. A reliable choice for daily hydration.
Moderate — Acceptable composition with some elevated or deficient minerals. pH may be slightly outside optimal range.
Poor — Significant mineral imbalances, elevated sodium or fluoride, or pH outside recommended range. Not ideal for regular use.
Avoid — Fails multiple quality criteria. Extremely high sodium, mineral imbalances, or pH well outside safe range. Not recommended.
The grade is calculated from a weighted formula evaluating mineral balance across all eight tracked minerals, pH range adherence, sodium concentration relative to dietary guidelines, fluoride levels, and overall suitability for sensitive populations including infants.
