£90 myzeo.co.uk
Zeo’s headband-mounted sensor reads brainwaves to tell your iPhone what kind of kip you’re having – deep, light or REM (dream) sleep – then maps the data into a graph. It’ll even give you a score so you’ve got a tangible target in your quest for quality shut-eye. Do androids dream of electronically quantified robo-sheep? Oh yes.
