If you leave a complaint in a review please leave your callsign so I can get in touch with you to fix your problem, or email me directly. I cannot reply to reviews. Please NOTE: This application is not meant to replace a more formal method of logging such as a computer based logging application or the classic paper method. It is more for quick logging while portable or mobile. Personally, I transfer all contacts to paper after coming back from field QRP fun. Regarding IMPORTING: As of December 8, 2010, HamLog support importing ADIF files. Please visit http://n3wg.com/hamlog for an example of how to import. I will happily respond to feedback, entertain feature requests, and answer questions directly, please contact me at the email address listed on n3wg.com or QRZ. Field Day Logging Info: Sections logged include: Date/time,Mode, Band, Callsign, Class, Section, Operator, Comment Exporting: Exporting logs from the Field Day tool is via e-mail in the form of a CSV file that any spreadsheet program can open. Dup Detection: The app does the standard dup detection you would see in a PC/Mac based app. There is no inter-device dup detection. Dup detection between devices is an exercise left to the exported spreadsheet application of choice. iPad Specifics: Sections worked are shown vs sections not worked for each zone. NOTE: While I try my best to ensure this Field Day logger is fault tolerant, I can make no guarantees or warranties. Please test and become familiar with it before using it live during Field Day. 73, N3WG http://pignology.net

xCluster is a visual display of dx cluster activity built for the iPad. DX spots are received via telnet or web services and displayed in a tabular form and plotted on a map of the world. You can filter the spots by call sign or band. Spots are created using the latitude and longitude of the dx station and spotter. The program has an internal call parsing component to determine the country for each call but can use QRZ.com for more accurate location data. Lookup priority is QRZ.com with the the call parser as a backup. DX spots can be displayed on a map or in a tabular form. Alerts for specific stations, bands or countries may be set and will be highlighted in the list and on the map. A number of major telnet clusters are built in along with DXSummit and PSK Reporter. PSK Reporter will display other stations that can hear your signal. You must be running WSJT-X or FLDIGI and have it configured correctly to work. You may contact the author with questions, suggestions or issues at support@w6op.com Features: Display dx spots on a map and in a list Predefined cluster servers and websites Filter by band and call sign Set alerts for display in the list and on the map Alerts can be set by country, band and call sign Save alerts in iCloud Built in call parser if QRZ.com is unavailable Freeform cluster command input Zoom and pan the map display

Verdict
The clearest difference is price: xCluster at Free against HamLog's $0.99. xCluster also leads on review sentiment (100% vs 76%) and rating (4.0 vs 3.7). HamLog's advantage is ratings volume (59 vs 5) and chart position (#198 vs unranked). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
