The Story Behind SoifGo

SoifGo started as a personal project. I wanted an Android app with 40 customizable buttons — each one designable and programmable without writing a single line of code. But over time, the limitations became clear. No matter how many options I added, the app could never be flexible enough. I hit a wall.

Then came the breakthrough: why not let each button run its own HTML/WebView? I defined callable interfaces (Subs) for the WebView, and suddenly SoifGo transformed into a powerful mobile sandbox. Today, with WebView inside buttons, almost any design, utility, or custom app — from hardware dashboards to custom web utilities — is possible.
