WSPRlite is a great little tools for DXpeditioners. Few DXpeditions are on all bands 24/7 so WSPRlite is the perfect way to use your antennas to maintain a presence while you are on other bands, sleeping or sight-seeing. Because it is so small you can take it in your pocket - and still get Worldwide performance. As an added bonus it allows you to spot the times of band openings while you sleep - data that you can use to inform your operating the next day perhaps?

A good example of this sort of use was the recent C6APY mini DXpedition to Berry Islands, IOTA NA - 054. There they used a WSPRlite while they slept.
