LY4A DX Reminder
DX cluster alarm for hams
Free · Designed for iPad. Not verified for macOS.
Tell it which callsign you are waiting for, on which bands and in which mode. From then on ly4a.com watches five DX clusters for you every minute and sends an alert to your phone the moment that callsign shows up — on the lock screen, with the frequency, band, mode, spotter and source.
• Five sources at once — DXScape, DXSummit, DXHeat, PSK Reporter and Reverse Beacon
• Band and mode kept apart — 20m CW and 40m SSB never mix, and CW means real CW only
• 160m to 70cm — all HF bands including 60m, plus 6m, 2m and 70cm
• Five modes — CW, SSB, FT8, FT4 and RTTY
• Checked every minute — by ly4a.com, so the app does not need to stay open and does not drain the battery
• Alert repeat you choose — on every new spot, or at most every 1, 5, 10, 30 or 60 minutes for the same callsign, band and mode
• Spots list — every match, with time, frequency, spotter and source
• iPhone and iPad
• 15 languages — English, Lithuanian, German, French, Russian, Spanish, Polish, Italian, Ukrainian, Czech, Portuguese, Japanese, Latvian, Estonian and Hungarian
Free, no ads, no account. The app keeps only what it needs to work: an anonymous device identifier, your notification token, the callsigns you watch and your alarm settings. Nothing identifies you, and deleting the app removes it all.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Delete spots — remove a single entry, or clear the whole history from the title bar
• The spots list now refreshes by itself while it is open, instead of waiting for the button
• Callsign chips wrap onto a second line, so the fifth callsign is no longer squeezed
• Alerts are now sent as time-sensitive notifications, so they come through while a Focus mode is on
• Fixed the version line in About
