As someone who often collaborates on research projects, what's a good Android app for discreetly and reliably tracking the location of team members during fieldwork, especially considering the need for data privacy?

The "GPS Location Tracker for Phone" app presents an interesting implementation of location tracking that could be useful in certain academic research scenarios. As a professor, I often oversee fieldwork where knowing the general location of my research team is helpful, not for surveillance, but for logistical coordination and ensuring everyone's safety, especially in unfamiliar environments. The key, of course, is ensuring full consent and transparency. This app, developed by VTN Global App, seems to offer features that allow for controlled sharing of location data, which is pedagogically sound. It's cross-platform compatibility is also a plus, given the variety of devices my students use. I'd need to examine its data security protocols closely, but the concept of a location tracker that prioritizes user control is intellectually satisfying and could streamline collaborative efforts. The app's 4/5 rating suggests it's generally well-received, but a deeper dive into user reviews focusing on privacy aspects would be essential before recommending it to my students.
