Vision8 Devlog #1 – Start Screen and Testing Interaction

This weekend, I built the first working interaction in Vision8: a start screen and a basic vision test flow.

The test is simple — you press “Start Test” and see an arrow on the screen.

What I built today

• A Start Screen with a single button to launch the test.
• A Test Screen that:
  • Shows an arrow in one of four directions.
  • Asks the user whether they saw the arrow.
  • Changes the arrow size depending on the response:
    • Seen? → smaller (harder)
    • Not seen? → bigger (easier)

This structure mimics how eye doctors test vision, but without needing an actual doctor present.

So I decided to name this software Vision8 a long time ago.
Since this is going to be presented on the App Store, I needed a logo.
I tried to blend the ideas of vision, eight (8) (which sounds like aid), and medical accessibility.
I scattered these three ideas, and decided to stick with this one:
