TowerScope turns independent cellular observations into a map you can understand. Search cities, addresses and countries worldwide, explore 2G, 3G, 4G and 5G records, and inspect the information behind each result. EXPLORE THE NETWORK โข Browse cellular records on a clear map โข Search worldwide for a place or country โข Filter by radio technology, carrier and point type โข Switch between standard, hybrid and satellite maps โข Inspect Cell ID, MCC/MNC, area code and coordinates โข Review samples, dates, estimated range and quality โข Open coordinates directly in Apple Maps โข Optionally test latency, download, upload and ISP/ASN HONEST DATA, CLEAR LABELS A marker is not automatically a physical tower. It may represent a logical cell, sector, observation or estimated site. Labels, sample counts and dates help you judge each result. Coverage, recency and position quality vary by region. A missing result does not mean that no cell exists there. WORLDWIDE SELF-HOSTED DATA TowerScope retrieves records from its own backend. The worldwide dataset is based on OpenCellID observations. Possible frequency bands are catalog entries for a radio generation, not a promise about the exact band used by a cell. Source and license information is available in the app and privacy policy. ONE PURCHASE Unlock access with one lifetime in-app purchase. There is no recurring fee, advertising or TowerScope account. Purchases can be restored through Apple. The optional connection test transfers up to about 16 MB and describes your current internet connection, not a specific tower. TowerScope is an information tool, not a substitute for professional measurement equipment, carrier planning data or emergency services.

Verdict
The clearest difference is price: TowerScope at Free against DuctSizer's $4.99. DuctSizer's advantage is in-app purchases (none vs 1) and iOS requirement (12.0 vs 17.0). On update cadence, ads and device support there is nothing between them.
