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.

Verdict
The clearest difference is review sentiment: Survey Help at 50% against Cellr's 0%. Survey Help also leads on monetization model (free vs free with in-app purchases). Cellr's advantage is update cadence (every 3 weeks vs every 14 months) and rating (3.4 vs 3.0). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Survey Help sells 1 one-off in-app purchase and Cellr sells 5 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Cellr holds the better App Store score, 3.4 against 3.0. That said, the two scores are not equally well evidenced: Cellr has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Survey Help's written reviews are positive against 0% of Cellr's, so the app with the better star average is not the one people write more warmly about.
Survey Help ships an update every 14 months, Cellr every 3 weeks. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
