Use Your Smartphone Smartly: Apps in Ecological Research

Written by Soumya K.V.

Have you ever wondered what your smartphone can do besides making calls, waking you up, reminding you of things to do, navigating your way, accessing your emails, communicating with your friends, accessing social media, taking pictures, playing music and videos, and so on? We all have smartphones but do we use them smartly?

Nothing fascinates the ecologist and gadget freak in me more than a new smartphone app that can potentially be used in my research. There are  2.8 and 2.2 million apps available on Google Play Store and iOS App Store respectively for free or for an affordable price. Whenever I find time, I plunge into the Google Play Store on my smartphone looking for new apps and I think of how I can use these apps in my research.

If you are a tech-friendly person and ready to use technology in your research, there are many smartphone apps that can be very useful in ecological research. For a field researcher, apps on field safety, data entry, recording observations, field guides, mapping GIS and GPS, unit converters, random number generators, citizen science, analytical and communication tools can be very useful (and can also save a lot of paper). I have used most of these apps in my field research and they have helped me become faster, more efficient, and eco-friendly.

Many researchers, however, tend to think that apps are useless, a waste of time, and often unreliable. They question the apps’ ability to work in field conditions without internet access or electricity to charge one’s phone. Perhaps their lack of interest or skepticism in becoming dependent on technology also holds them back from widely exploring these technologies.

I wish I could share lots of examples of app-based ecological research, but there are relatively few success stories so far. But in this article, I will list various apps and their uses, and hopefully convince you to try out some of them in your research.

For instance, one app that I highly recommend for field data collection is Open Data Kit (ODK) Collect. I was introduced to this app in a workshop at ATREE. This app is freely available and is a good replacement for paper forms. ODK supports documenting geo-locations, images, audio-clips, video-clips, barcodes, numerical and textual answers. The app allows you to customize your form and collect data in multiple languages. And its best feature is that it is designed to work even without cellular network or Wi-Fi. Once the researcher is back within network coverage, the completed forms can be copied out of the device or safely exported for analysis to an independent and controlled server maintained by ATREE.

Here are some other apps that could be of immense help to you in the field.
