Really Neat Way to Look at the Sky!

This may not be brand new or flashy, but I really love the way this astrolabe visualizes the relationships between the celestial bodies as a function of time. If you actually read the instructions and play with the app you learn a lot about how things are related. Well done!

Perfect clock visual

Love how app shows solar & lunar positions & elevations correctly. The perfect fix to adjust to the idiotic standard-savings timeΔ.
Please add alarms & or ability for postings.
