iPhone
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.
