## What is TapSure?

Know before you sip. TapSure helps travelers understand whether public tap water at a destination is generally suitable, needs local confirmation, or calls for a more conservative option.

Search 229 cities and service areas across 92 countries and territories. Every result is written from reviewed evidence and clearly shows its confidence, coverage, freshness and limitations.

Free features:
- Search every included destination
- See the essential drink-or-avoid recommendation
- Open three detailed water reports
- Save three cities for a trip
- Review the source, date and evidence limits

Premium Traveler adds:
- Detailed official-evidence summaries
- Water-hardness reports where evidence supports them, with exact values, ranges, supply zones or clearly labeled likely-hardness estimates
- Service-area and neighborhood context
- Building plumbing and storage-tank limitations
- Baby-formula preparation context
- Coffee, tea and filter guidance
- Unlimited saved cities

TapSure is travel guidance, not a medical diagnosis and not a guarantee for an individual tap. Conditions can vary between utilities, buildings and temporary local events. Check current utility or local-health notices before drinking.
