Know exactly when to look up.
Quick ISS is a beautifully minimal Android home-screen widget that counts down to the next time the International Space Station will be visible from where you stand — bright, overhead, and worth stepping outside for.
No app to open. No alerts to configure. Just a live countdown on your home screen that ticks toward the moment, tells you where the station will rise and how high it will climb, then quietly rolls over to the next pass.
- Visible passes only — filters out the dozens of daily passes you can't see; shows only the ones where the ISS catches sunlight in a dark sky
- Live countdown — ticks in real time on your home screen, battery-friendly
- Sky path at a glance — rise direction, set direction, and peak height
(e.g.
NW → SE · max 61°) - Works anywhere on Earth — any latitude, any longitude, automatically
- On-device orbital computation — predictions are computed right on your phone from live public orbit data
- No ads. No tracking. Your location never leaves your device
- Set-and-forget — updates itself for days ahead, even offline
Coming soon.
