Back to 5 stars and loving it! ### 5/5 — Works great *2023-07-29* The app works great on iOS 16.6. For those experiencing crashes, try deleting it and reinstalling - this worked for me. ### 1/5 — Doesn’t work anymore needs update ASAP *2023-02-03, version 1.4.11* Doesn’t work anymore needs update ASAP. Just crashes on launch. Please add a satellite footprint view option on the map screen when a satellite is selected. ### 1/5 — No worky *2022-07-23, version 1.4.11* Crashes when you try to open it. iOS15.5 ### 5/5 — Trying.. *2022-04-15, version 1.4.11* How do I see uplink and downlink freqs? I see Doppler offset.. ### 1/5 — Doesn’t work anymore *2022-03-16, version 1.4.11* It will not load. Don’t know why. It used to work well but now just crashes when I open it. ### 2/5 — Unusable now *2021-10-01, version 1.4.11* Was a great app up until an update about a year ago. Now it crashes every time you open it and it’s completely unusable. ### 5/5 — Works flawlessly *2021-06-28, version 1.4.11* This app is by far the best for satellite prediction that I have ever used. It is accurate and very easy to use. ### 5/5 — Love the app (Highly Recommend) *2020-05-26, version 1.4.11* I’ve tried many Satellite tracking apps, but love this one by far. It does most of what I need it to do. It’s simple and easy to setup. I have recommended it many times to others that are looking for which app is the best. My suggestion for one improvement that would be helpful as a Sat Op is an elevation minimum setting that can be used to filter the calendar of Sat passes. It could be configured in settings or applied from the calendar section. Store a value and apply to calendar results. It would be handy to have as it would allow me to see all the passes i I’m interested in working for that day. Thanks and keep up the excellent work. 73 AI4Y ### 2/5 — Promising *2020-05-12, version 1.4.10* Nice looking UI. The + button on the My Sats tab causes an immediate exit (v 1.4.10). With my device in dark mode and the SatSat dark mode settings switch turned off, there’s a lot of white on white text in the Settings tab. With device dark mode on, SatSat dark mode off, there’s a lot of black on gray. ## Frequently asked questions about SatSat ### What does SatSat do?
