With Status App you are able to explore the profile of any summoner on League of Legends, as the live matches and week rotation.
Enough with 'alt+tab' on the loading screen and web queries... ;-)
Enter the name of any summoner of the registered region and find information as: Level, tier, statistics on ranked & normal games, as the summary of the last 10 matches.
Check out in progress matches information with a summary of each player, obtain: Tier, mastery, spells, champ mastery and runes. It is practical to consult your own summoner to see the rest.
