What is the point of having geolocation activated, then? ### 1/5 — I can’t get past the legal disclaimer screen. *2022-10-30, version 3.7.4* I can’t get past the legal disclaimer screen. Nothing happens when I press “agree.” ### 1/5 — Update issues *2022-06-12, version 3.7.3* Since the app was updated I can no longer rotate the screen to make it wider for the world view. Also no place to report this problem as all links on the page don’t work. ### 5/5 — Love it *2022-04-15, version 3.7.0* I've been using this on my iPhone for a while and I saw it now on the App store. Great job and a great tool. ### 2/5 — Too hard to use. *2021-12-09, version 3.7.2* I like the tools. But they are too hard to discern how to use. Most frustrating is how to change cities. ### 3/5 — Worked great for years until last update. *2021-01-21, version 3.7.1* Thus app was flawless and worked great for years until last update. Crashes when selecting Events option. ### 2/5 — No longer working on iPhone *2020-12-14, version 3.7.0* I love this app, but it seems that I can only use it on my iPad these days. On my iPhone there seems insufficient space for all the text, and I can’t scroll through to select days. Such a shame. ### 1/5 — Phoenix *2020-09-10, version 3.7.0* The app does not include the 5th largest city in USA. The problem with latitude and longitude is the land size of Phoenix. ### 5/5 — Brilliant Program But The Last Update Broke It... *2020-06-18, version 3.7.0* I’ve had SunGraph on my iPad’s now for 6 or 7 years, and it’s a brilliant program that does exactly what it sets out to do - show you the sunrise and sunset times every day of the year. Sadly, the update a month ago broke it - the program now no longer updates time. My copy is stuck on June 7th 2020 at 07:41AM and doesn’t update to the current time any more. ## Frequently asked questions about SunGraph ### What does SunGraph do?
