Know when a band opens from where you are. HAMSignal watches live NOAA solar data and tells you when HF conditions improve at your QTH — not just when a storm hits. Set your callsign and grid once, and your phone (or Apple Watch) buzzes when 10m, 15m, or 20m opens. BAND-OPENING ALERTS • A notification when a band opens from your grid square, checked in the background while you're away • Based on live SFI, K-index, and A-index, with a day/night model per band • Especially useful on 10m for Technician licensees, and more valuable as Solar Cycle 25 declines and openings get rarer LIVE CONDITIONS • All HF bands rated open, fair, or closed for day and night at your location • SFI, K-index, A-index, X-ray flux, and solar wind from NOAA SWPC • 27-day NOAA forecast and historical trends • Grey line / terminator map with your local sunrise and sunset • Point-to-point path predictor with MUF/LUF and best band WHAT CAN I WORK RIGHT NOW?

Verdict
The clearest difference is rating: HAMSignal at 5.0 against AntScope's 2.3. HAMSignal also leads on update cadence (every 11 days vs every 3 months). AntScope's advantage is monetization model (free vs paid) and review sentiment (21% vs 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. Neither carries in-app purchases, so what you see is what you pay.
HAMSignal holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: AntScope has 58 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 21% of AntScope's written reviews are positive against 0% of HAMSignal's, so the app with the better star average is not the one people write more warmly about.
AntScope ships an update every 3 months, HAMSignal every 11 days. The most recent releases landed on October 21, 2026 and October 22, 2026 respectively.
