Oasis Health App

Science-backed water & filter picks

We drink water every day. It’s a major cornerstone of our health and vitality. But what do we really know about the quality of our tap and bottled water choices?

Oasis rates bottled water, tap water by city, and filters using independent lab tests and a transparent scoring system. It’s already productizing trust: a fast, mobile-first directory with top rankings, map-based tap ratings, and a clean Pro tier that funds testing (no ads). If they keep expanding into more and more products, Oasis graduates from a helpful consumer app to the default health-grade for everyday items.
