The 3 apps that I use the most in the field are Trimble Navigator, Calc Pro and Youtube Capture. Calc Pro serves the purpose of a scientific calculator and Youtube Capture is an easy way to take a series of quick video snippets and then easily edit and upload when I'm back in Wi-Fi range.
There are other GPS apps that I'm sure can serve the same purpose as Trimble Navigator, but it's just the one that I gravitated to. Here are the features/benefits that I find helpful:
Records Your Track/Path - I enjoy seeing this when I'm done and helps in the field when determining the best way back to the starting point.
Mark Waypoints - Avoids the problem of forgetting where a tree is.
Geo-tagged Photos - This really helps to avoid the situation when you can't remember which photos match up with which tree. The photo can be named with the measurements of the tree. If someone prefers to use a real camera, then the iPhone can be used for a snapshot of the same scene that the real camera captured.
Can save trips to trimbleoutdoors.com and can also pre-plan trips and enter waypoints before you leave home.
The Pro version ($4.99) allows you to download maps to your phone so that you'll still have the map if you travel outside of cell phone coverage. Satellite coverage still keeps track of your location, but having the downloaded map is nice so you can still see your location on the map. When travelling outside of cell phone coverage it's good to have the app running while still within cell phone coverage so that there is a smoother transition from cell phone/satellite coverage over to strictly satellite coverage.
I also carry an IOGear 11,000mAh capacity recharger, which can recharge the iPhone multiple times.
FYI, Trimble is sunsetting their Outdoors Navigator app :(
For data collection, a GIS approach will probably produce a better result anyway. Trimble was good at navigation, but probably not the best way to display the collected information in a way that can be customized. I'll do some research and see what works best.
