Cellr vs SigLens

Cellr maps every cell tower around you so you can find the closest signal source, point your antenna, and understand your coverage. WHY CELLR? Whether you live in a rural area on the edge of coverage, work from an RV, run a wireless ISP, or just want to know which carrier owns the tower outside your window — Cellr turns the invisible cellular network into a clear, interactive map. FEATURES • Live tower map — pan and zoom to see LTE, 5G, GSM, UMTS, and CDMA towers around your location • Distance and bearing — Cellr calculates how far each tower is from you and which compass direction to face • Built-in compass — align your phone (or directional antenna) at any tower with the live magnetometer compass • Tower details — radio type, carrier, MCC/MNC, LAC, cell ID, sample count, and approximate range • Coverage overlay — terrain-aware viewshed shows the line-of-sight footprint of any tower • Carrier filter — show only towers from a specific carrier (Premium) • Nearest list — sorted list of the closest towers with quick-tap details WHO IT'S FOR • Rural residents looking for the strongest signal • Travelers, vanlifers, and RV users planning routes around coverage • Network engineers and antenna installers aligning directional gear • Curious tinkerers who want to know what's broadcasting nearby PRIVACY Location is used only on-device to compute distance and bearing to nearby towers — Cellr does not sell or share your precise location. Tower data comes from public crowdsourced datasets. NOTE Tower positions are crowdsourced approximations of cell-site locations. Coverage estimates are computed from public terrain data and are intended as planning aids, not guarantees of service.

SigLens is a focused utility for locating cellular towers and understanding carrier coverage across the United States. Whether you are a traveler, a remote worker, or a tech enthusiast, SigLens helps you visualize the cellular infrastructure around you. Using the OpenCelliD database, SigLens provides a clear, map-based view of cell towers from major US carriers. Instead of guessing where your signal is coming from, you can see the physical locations of the towers that power your connection. Key Features: - US Tower Map: A clean, interactive map showing cell tower locations across the United States. - Carrier Filtering: Filter towers by carrier (MCC/MNC) to see the infrastructure relevant to your service. - Tower Details: Tap any tower to see its unique identifier (Cell ID), radio type (LTE, GSM, UMTS), and approximate location. - Offline Search: Search for towers in specific areas even when your connection is limited. - Privacy First: Your location is used only to center the map and find nearby towers. No data is collected or shared. Honest Framing: SigLens is a tower locator and map utility, not a live signal meter or speed test tool. It does not display real-time signal strength (dBm), RSSI, or "bars" from your device's hardware, as iOS restricts access to this data. It does not perform network speed tests or crowdsource signal data. Tower data is provided by OpenCelliD and is subject to their database coverage and accuracy.
