It does not take a lot of memory on the iphone, decent graphics but slightly different user interface that is currently hard on senior eyes. I was able to run the night sky backward just over 2000 years ago, very nice. I was not able to figure out how to change my viewing location if I wanted to see the night at a different location. This version had no ads which is also nice. It has earth and 7 planets, 88 constellations and a handful of NGC’s along with night vision. If the GUI was easier to see I’d increase my rating. ### 3/5 — ความลื่นไหล *2024-09-07, version 1.08b* การใช้งานยังไม่ค่อยลื่นครับ การหมุนเปลี่ยนวันใช้งานค่อนข้างยากครับ มันไวเกินไป ### 4/5 — ความกว้างของมุมมองในแอป *2024-01-25, version 1.03b* อยากให้มุมมองในแอปกว้างกว่านี้ครับ ### 5/5 — Easy to use for everyone who loves stargazing *2024-01-13* This app is easy and fun to use for those who are interested in stargazing as a hobby. It can be a great companion for everyone to check various celestial objects on the app before going out to look at the actual night sky. User can modify the date & time to see the whole sky as the time goes by. Enjoy stargazing! ## Frequently asked questions about NAPA ### What is NAPA?
