01Problem

Learning to trade usually means putting real money on the line before you know what you are doing. A beginner needs a place to make mistakes that cost nothing.

02Approach

A practice trading app built as a mobile web app. It runs in the browser on a phone and can be added to the home screen with its own icon, so it opens like an app. People try mock trades with practice money, and nothing real is at stake. It is a mobile web app and is not in any app store.

03Result

Live at playdryrun.com as a mobile web app that can be added to the home screen.

Under the hood

Sign-in runs on Better Auth and the data lives in Neon. The home-screen install uses a web app manifest and icons.
