Overview
Cash App, developed by Block (formerly Square), lets you buy Bitcoin in seconds from your phone with no prior crypto experience required. It's the simplest path from zero to Bitcoin ownership in the US market. The app doubles as a peer-to-peer payment tool, debit card, and bank account — Bitcoin is just one feature, which keeps the experience approachable.
Cash App also supports the Lightning Network for near-instant, near-zero-fee Bitcoin transactions once you own it. You can deposit cash at participating retail stores (Walmart, Walgreens, etc.) and use it to buy Bitcoin — making it genuinely useful for unbanked buyers. The fee spread is higher than dedicated exchanges, but for convenience and speed, it's unbeatable.

Verdict
Cash App is the entry point for mass-market Bitcoin adoption. If you want to buy $20 or $200 of Bitcoin right now with zero friction, nothing beats it.
