What's New in Caelo
1.1.0
November 2, 2026
Caelo now supports Widgets! - Add Caelo to your home screen or lock screen. Caelo Pro shows the Tonight verdict (small) and This Week (medium). Caelo now has support for the Milky Way as a special object type. With a Sky Profile, Tonight will show you whether the Milky Way's core is up in the dark, or what may be in the way when it isn't. A new Milky Way detail view lets you slide through the night to see when the Milky Way core and band are visible from your backyard. Explore view starts on what's visible tonight. Switch to All objects to show the rest. Filters have moved to a new standard UI. Any filters you apply will show up as chips, and you tap a chip to remove it. Caelo's catalog of objects will now show you which objects will look small (or large!) based on your telescope without needing to go into the object's detail view. Caelo allows you to configure the faintest target you're interested in (per Location) and Tonight and Explore will hide anything fainter. No more being tempted by faint targets. Settings also introduces "Hide small targets" which will no longer show any small targets (based on your telescope) from Tonight or Explore. It needs a scope that reports its pixel size. The 7-Day Outlook now indicates more clearly which nights forecasts are firm versus indications only. The first three nights are a forecast, and the next four are more indicative than a forecast. Sky plots can now automatically rotate to the way you're facing. Settings has a new Send Diagnostics option. If something isn't working right for you, Caelo puts together a file to send to me (it will show you all of it) and opens an email (or the share sheet) you can send yourself. Nothing is sent automatically. Settings also has a Tip Jar with three optional tips you can generously contribute. A tip does not change what Caelo does, but does make me feel warm and fuzzy inside! (thanks in advance)
