Looking for *simple* app to replace Gowalla 4

[ned23]

Looking for recommendations for a simple geo-location/social network app to replace Gowalla, since Gowalla 4 seems unusable now. The ideal app would preferably have the following abilities:

1. 1. Ability to easily record the location of spots visited
2. 2. Ability to correct spots that you create for accuracy
3. 3. Ability to post your location on a social networks on demand
4. 4. Ability to easily recall all places that you've ever visited, particularly when you return to an area
5. 5. Ability to accomplish items #1-4 with fewest keystrokes and complex graphics as possible

Ads or any other stuff is fine as long as it doesn't hinder usage. If it does other stuff, that's fine too. I don't need the app to coodinate to other users; I can use G+ , FB or twitter to find out where friends are. But if it does that's fine too. Thanks.
