Accessibility

TrackThat is meant to be usable on a bad screen, in a barn, at night, with tired eyes. Most of what follows is not a feature you turn on. It is how the app was built.

Contrast

Every colour pair in the app is measured rather than eyeballed, against the background it actually sits on.

Text meets or beats the 4.5:1 ratio the accessibility guidelines ask for, and most of it clears that by a wide margin. Where a colour serves two backgrounds, both are measured, so nothing reads well in Day and turns to mush at Night.

Day, Night, and following your device

The theme has three settings and they live in Settings: Day, Night, or Follow system, which does whatever your device is doing and changes when it does.

Night is a real second palette, not a dimmed copy. Every surface, border and alarm colour has its own value there.

Colour is never the only signal

Nothing in the app is told by colour alone. A warning says what is wrong in words, a Card’s colour is decoration over a name you chose, and a Tag’s colour sits beside its name rather than replacing it.

The keyboard

Every control is reachable and operable by keyboard, in the order it appears on screen. A few single keys reach the busiest places, and they are listed in Keyboard Shortcuts.

Esc closes any dialog, always, including the ones that ignore a click outside.

Screen readers

Icons are decoration and are hidden from screen readers, so a button announces its words rather than the name of a glyph. Icon-only controls exist only for display controls that change the view, and each one carries its own spoken label.

Quoted controls in this Handbook are pictures of the app rather than working controls: a screen reader announces what each one is, and the keyboard skips past them.

Nothing disappears before you have read it

TrackThat has no messages that fade away on a timer. What is happening stays on screen while it is true, and an outcome appears where you are working and waits for you.

That is deliberate. A message that vanishes after four seconds is a message that people who read slowly, or who looked away, never got.

Motion and video

Visual effects in Settings has three levels. Reduced stills the app’s animations; Minimal also stops video previews from playing on their own.

Your words stay your words

Names you type are shown exactly as you typed them, everywhere, with no capitals added or removed. If you write in a language, a case, or a shorthand that matters to you, the app does not tidy it.
