Use consistent animation.

Incorporate refined, unobtrusive branding.
Don’t let branding get in the way of great app design.
Defer to content over branding.

Use words only when they’re essential or part of a logo.
Keep icon corners square.
Test your icon against different wallpapers.
96. Icons
Custom Icons
“To create a filled-in version of an icon
that has interior details (such as the
Radio icon) invert the details so they
retain their prominence in the selected
version. The Keypad icon also has
interior details, but the selected version
would be confusing and hard to
recognize if its background was filled in
and the circles became white outlines.”
Excerpt From: Apple Inc. “iOS Human
Interface Guidelines.” iBooks.

Custom Icons
“Sometimes, a design needs a
slight alteration to look good
when it’s selected. For example,
because the Timer and
Podcasts icons include open
areas, the selected versions
condense the strokes a bit to fit
into a circular enclosure.”
Excerpt From: Apple Inc. “iOS
Human Interface Guidelines.”
iBooks.
98. Icons
Custom Icons
“If an icon becomes less
recognizable when it’s filled in, a
good alternative is to use a
heavier stroke to draw the
selected version. For example, the
selected versions of the Voicemail
and Reading List icons are drawn
with a 2-point stroke, instead of
the 1-point stroke that was used
to draw the unselected versions.”

Human Interface Guidelines.”
