What's new • Made for iPhone Duo — the Toolbox fills the whole display, folded or unfolded, and changes its layout when you fold or unfold the phone. Tool cards and calculator columns stay clear of the fold. • Layouts that fit your screen — tool grids, calculators and lists use the space they have, on every iPhone, on iPad and in iPad split view. Fixes • Clearances show inches — clearance figures were labelled "thou". They now show in inches. • DIY Mini Bot is easier to read on iPad — answers use a comfortable reading width. • Category chips stay clear of the toolbar on iPhone Duo. • An open service stays open when you fold, unfold or resize the app.
