Looking for app that tells of "free app of the day"

view full story

http://androidforums.com – I checked the Play store, and found a couple apps that are supposed to tell you about apps that are free for the day (usually a paid app), but one of them wants access to WAY TOO MUCH personal info from my phone/contacts, etc. The other isn't compatible with my phone because I think the app is for people outside of the USA. Are there any apps that tell the "free app of the day", or "the hottest free apps available (by category - Utilities, games, etc)? Please post names of them here if you know of any. Thank you.
