I am doing a forestry research. I need to record the geographical coordinates and altitude values of my experimental plot. Getting a GPS receiver is difficult for me and purchasing a GPS receiver is very expensive. I am thinking of using my smart phone (ios) instead of a GPS receiver. I do not know a very good, technically reliable ios application to get the works done. Please suggest me one ?
Also I need to know whether using a smart phone GPS application is a valid scientific method/scientifically acceptable in scientific researches ?
See this paper for an idea of smartphone GPS accuracy....

Dear Dr. Pete, I have tested forestry before, and found that due to the IOS system can't install open-source positioning applications, it can't achieve high spatial positioning; On the contrary, Android phones can install many open-source positioning software, which can achieve better positioning requirements.
Of course, non professional measurement tools must have a better measurement environment and satellite reception to achieve more satisfactory results.
