To complete my current series of Moleskine posts, I’ll mention the Moleskine app for iPad, iPhone/iPod touch. This official app lets you choose the style of paper you want for your notebook: ruled, plain, or grid. You can type and edit entries, insert images (including some provided by Moleskine), or sketch your own images with the sketching tool. A range of categories lets you catalog your entries for easier lookup later. You can even geo-tag your entries or share them with friends. The Moleskine app is free in the iTunes app store.
