cMe is a privacy-focused location sharing app for families, friends, trips, events, and outdoor groups. Share live GPS locations, view location history, and manage groups across iPhone, Android, and the web. Motion-aware location technology minimizes GPS use when you’re not moving, while on-demand data syncing reduces unnecessary network traffic—helping save both battery and mobile data.

Hi Product Hunt! 👋 I built cMe because location sharing is useful in many situations beyond simply finding a phone — staying connected with family, coordinating with friends, travelling together, or keeping track of a group during outdoor activities. One of the challenges with location-sharing apps is that continuous GPS tracking can consume battery and generate unnecessary mobile data. I wanted cMe to approach this differently. cMe uses motion-aware location technology to reduce GPS activity when the device isn't moving and dynamically adapt location updates as movement changes. It also uses on-demand syncing: high-frequency real-time location updates are sent when someone actually needs to view them, rather than continuously transmitting the same type of data when nobody is watching. This helps cMe provide live location sharing while reducing unnecessary battery usage and network traffic. Beyond live GPS sharing, cMe supports location history, privacy controls, privacy zones, and different types of groups for families, friends, trips, events, and outdoor activities. It works across iPhone, Android, and the web. I'm continuing to improve cMe based on real-world use, and I'd especially love feedback on the group experience, location-sharing controls, and our approach to battery- and data-efficient location tracking. Thanks for checking out cMe!

How should location-sharing apps balance real-time tracking, battery life, and privacy?

Building cMe has made me think a lot about a trade-off that almost every location-sharing app faces:

How do you provide useful real-time location updates without unnecessarily draining battery, using too much mobile data, or compromising privacy?

My current approach with cMe is to make location sharing adaptive rather than continuously aggressive.

cMe uses motion-aware location handling so GPS activity can be reduced when a device is not moving, and location behavior can adapt as movement changes. It also uses demand-driven synchronization: high-frequency real-time location updates are prioritized when someone is actually viewing a group, instead of continuously transmitting the same type of data when nobody is watching.
