Got an iPhone app project and would like to get feedback on users noticing bottom bar actions i.e., share, add something, or delete? I've noticed some difference of opinions with my peers where some may feel putting actions in a bottom toolbar on a tablet may be diminished if the user isn't guided visually (too much negative space) with some eye tracking to the toolbar area.
My assumption is most apps on a tablet invite more exploring than with users on the phone viewing in short bursts. Noticing a bottom toolbar should be minimal.
Thoughts?
