Oasis

A mobile app that rates the quality of bottled and tap water, helping health-conscious consumers make informed hydration choices based on contaminant levels, mineral content, and overall safety. Built as a solo founder project, Oasis grew its user base almost entirely through TikTok content that turned water quality awareness into a viral topic with a passionate community. Monetized through a subscription model, the app generates $24,000 per month in revenue — demonstrating that a focused niche product paired with the right distribution channel can produce significant recurring income.
