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

SP2ALERT is an alert app for amateur radio operators that delivers real-time push notifications for new POTA (Parks on the Air) and SOTA (Summits on the Air) spots. ■ POTA / SOTA Spot Alerts Automatically detects new spots and sends push notifications — even when the app is in the background. ■ Three Alert Modes (foreground only) • CW Vibration — vibrates in Morse code pattern (adjustable WPM and amplitude) • CW Tone — plays Morse code through the speaker (300–1500 Hz pitch) • Voice — reads spot information aloud (phonetic alphabet supported) ■ Flexible Filtering • Filter by band and mode (all bands from 160m to 13cm supported) • Filter by POTA program (JP, K, VK, etc.) or SOTA association • Include/exclude specific callsigns, park references, or summit references • Save and switch between multiple named presets ■ Hunt / Chase Management • Import POTA Hunt and SOTA Chase history via CSV • Alert only for unworked parks and summits • Multi-location activations (same operator at multiple parks) are always alerted even if one park is already hunted ■ Notification Controls • Configurable polling interval • Alert time window (e.g. 7:00–22:59 only) • Re-alert interval • Alert expiry timer • Additional alert on frequency/mode change ■ English / Japanese Localization The UI automatically switches between English and Japanese based on your device language setting. 【iOS Limitations】 Background operation is limited to notification banners and sounds. CW tone, voice, and vibration alerts only work while the app is in the foreground. Background polling timing is controlled by iOS and may be delayed beyond the configured interval.

Verdict
The clearest difference is price: SP2ALERT at Free against HamLog's $0.99. SP2ALERT also leads on update cadence (every 2 days vs monthly). HamLog's advantage is iOS requirement (12.0 vs 16.0). On ads, in-app purchases and device support there is nothing between them.
