At AdventureNomad.blogspot.com they have the following Conclusion (Feb, 2013),

For adventure and travel, I'd go with Gaia GPS. The additional maps on Gaia GPS gives users a lot more versatility and accuracy; plus the ease and speed of map downloads over MotionX wins me over. However Gaia takes longer to learn.

AdventureAlan.com says, Gaia GPS provides Satellite imagery and OpenCycleMaps in addition to USGS, and has a richer set of features, but takes longer to learn to use. For a user who wants the most complete set of functionality and the best selection of map sources, this is the best available app for the US and Canada.

Note: Turn the GPS off when not in use.  It drains the battery.
  If Tracking is off and the app is in the foreground when the iPhone is put to sleep,
  quite a few of the apps  tested incurred a battery drain of between 2 and 7% per hour.
  Optimal battery performance is at 68°F.  Avoid overheating or extreme cold.

My Tracks www.google.com/mobile/mytracks/ Description:
My Tracks records your path, speed, distance, and elevation while you walk, run, bike, or do anything else outdoors. While recording, you can view your data live, annotate your path, and hear periodic voice announcements of your progress.
With My Tracks, you can store your tracks with Google Drive, Google Maps, Google Fusion Tables, or Google Spreadsheets, or export your tracks to external storage. With Google Drive, you can also sync your tracks, share tracks with friends, and see the tracks your friends have shared with you. With Google Maps, you can share the map url with friends via Google+, Facebook, Twitter, etc. With export to external storage, you can select GPX, KML, CSV, or TCX format.
My Tracks uses the GPS sensor in your device to record geographic and velocity statistics, but the app also syncs with third-party biometric sensors, including:
- Zephyr HxM Bluetooth heart rate monitor
- Polar WearLink Bluetooth heart rate monitor
- ANT+ heart rate and speed distance monitors (these require an ANT+ compatible phone)

Geocache placer 4.4 is a tool for Geocachers, who wants to place their own Geocache, with a very precise position. By averaging many positions you will get a position with a +/- 2 meters / +/-6 ft.
That's BS. It averages over a minute or so, but when you take readings 90 minutes apart (recommended time for significant change in satellites) the averages will vary by 20-40ft.)

There are map apps that allow you to download maps onto your phone and use them without a cellular connection. Two of my favorites are MotionX-GPS and Topo Maps. MotionX has many of the functions of a dedicated gps unit such as tracking, odometer, elevation gain/loss, etc. Topo Maps allows you to download USGS topo maps to your phone and see exactly where you are on the map. Combine this with a paper USGS map and locating where you are on the map is made simpler.
