I love a good flowcharty brainstorming session, with mindmaps and any other old rubbish chucked up on a white board to distract from the need to actually do some proper work. There are thousands of well-regarded business managers unable to express themselves without reaching for a marker pen, y’know.

If you’re one of them, ZeptoPad is an essential purchase on the iPhone App Store. It lets you scribble on the touchscreen or type on the pop-up keyboard, to bring your ideas to life. And when finished, you can email the image file to your colleagues.

(Yes, if you’re juvenile, you can just draw rude graffiti and email it to friends too).

There’s also a neat feature that lets you transfer your ZeptoPad drawings directly to other iPhones by ’shaking & sharing’ - I think this involves the motion sensors. For all my mickey-taking at the start of this piece, ZeptoPad could be really useful if you ever need to get visual ideas down without then losing the scrap of paper you wrote them on. It costs £5.99.
