Ratings and Reviews
...in landscape orientation and when “adding a place” through finding on map. App crashes if “layer select” on bottom right of map is used. Seems there is issue with the interface between your app and the iOS map app.
...in portrait orientation attempting to adjust map settings/layers it closes the map...not the whole app like in landscape. Hope this helps you fix issue.
With the latest version you can tilt the map using the standard two-finger-swipe-up gesture.
Also, when returning to the app, it defaults to the location that was selected the last time you used the app. To go to the current location you have to explicitly tell the app to do so by tapping on the GPS symbol.
This is a fantastic app — as it always has been — it works very well with the latest (as of December 2017) iPhone OS. I especially like the customizable alarms which you can set for any number of celestial events.
Keep up the good work guys!
would be 5, if they ever responded
It's actually closer to five stars — my only issue is that they never respond to my questions.
Also: unless they’re using different calculations than most astronomers, their LQM and FQM times [in “alarms”] are often off, by at least half a day.
