FAQ

Q: Which mobile network standards does Tower Collector support?

A: The app works with all major cellular technologies, including GSM, UMTS (3G), LTE (4G), CDMA, TD‑SCDMA, and the newest 5G NR bands. It automatically detects whatever network your device is connected to and logs the corresponding tower information.

Q: How does Tower Collector help open‑source databases?

A: When you choose to share your measurements, the app sends anonymized tower data to projects like OpenCellID.org and BeaconDB. These initiatives compile the contributions into publicly available maps that anyone can use for network‑based positioning or research without needing an active GPS fix.

Q: Is my personal information collected or stored by the app?

A: No. Tower Collector is designed with privacy in mind and does not gather any personally identifiable information such as your name, email, phone number, or device identifiers. All data that leaves your device is stripped of any details that could trace it back to you.
