Features
Everything SkyWave shows you on first launch.
SkyWave’s first screen is the Go screen. Everything else supports it.
One band. One read. Everything else explains why.
A single recommended band, a confidence read, and a trend arrow. Tap it to open a bottom sheet that explains what's happening and what would change the verdict.
- Local Propagation card. The NVIS sandwich draws the foF2 ceiling, the D-layer absorption floor, and the amateur bands on one chart so you can see which bands sit inside the working window.
- Band pills. Every HF band, color-coded by current condition. Tap one for the band's read and the inputs behind it.
- Live metrics row. MUF, foF2, Kp, F10.7, and current geomagnetic state, with tap-through explanations.
- Stale-data banner. If the last fetch is older than an hour, the Go screen tells you so plainly.
Short-skip propagation lives inside a narrow window.
SkyWave's NVIS card draws that window so it's a glance, not a calculation.
- The foF2 ceiling caps the top. Above it, signals are likely to pass through to space.
- The D-layer absorption floor sets the bottom. Below it, signals are likely absorbed.
- Amateur bands sit inside the chart, color-coded by their current relationship to the window.
This is where 40m and 80m short-skip decisions live; the card updates as the ionosphere changes.
Compare paths before you pack the radio.
Add multiple Maidenhead grid squares. Each renders its own propagation summary so you can compare them at a glance.
- Add by call sign (HamDB lookup) or by manual grid entry.
- Reorder by drag, switch active location with a tap.
- Local-only. Stored on your device — no account, no sync, no cloud copy.
Use it for the home QTH, a portable spot, a cabin, a contest field, a friend's station.
Did the call match what you actually heard on the air?
Every band recommendation is recorded with the conditions snapshot that produced it.
- Grouped by day with timestamps in your local time.
- Each entry shows the recommended band, the metrics at that moment, and the location it applied to.
- Useful for building intuition over time.
History is local to your device.
Pass conditions along without paraphrasing the data.
Export a clean 1080×1350 PNG of the current conditions.
- Band recommendation with confidence and trend.
- Top metrics (MUF, Kp, F10.7) plus your grid and call sign (if set).
- App wordmark and a QR code that links back to the app.
- Native share sheet hands the PNG to Messages, Mail, Reddit, Discord, Slack, Photos, and the rest.
If you're offline, the card generates from the last cached snapshot and timestamps itself accordingly.
Glance at conditions without opening the app.
A widget for iOS and Android in three sizes.
- Small. Current recommended band, confidence dots, trend arrow.
- Medium. Top three bands by confidence plus the current Kp.
- Large. Six-band day/night summary plus a recent solar-flux trace.
Tap the widget to deep-link into the Go screen for the band shown.
Short by design. Skip what isn't critical.
A short first-launch flow.
- Welcome.
- Call sign entry (HamDB lookup auto-fills your grid and license class if found).
- Operating style and license class.
- Location: GPS permission or manual grid entry.
- Primer: one screen of "what you'll see and why."
