Normally when charging the Nokia N8, the regular black clock would appear but there’s always a way to swap it for a stylish clock, maybe you can also use it as a bedside clock.
picoBrothers, a developer company of many great apps has also developed this app which also again provides a good user experience as well as great response timings. You do get the options of a 24 and 12 hour clock as well as auto hide clock or not. Then at the bottom the Noght Light Pro is advertised for the user.
This app doesn’t have anything fancy but rather is kept real simple since its only purpose is to show time. NightLight is free but to have more options then NightLight Pro at the Ovi Store is recommended at the price of ZAR 9.
