If not - remove it from the store. ### 3/5 — Update? *2022-09-22, version 1.2* Please update the app. Thank you for your creativity. I would like to rate the app with as many stars as it deserves. ### 5/5 — great app but cant use since iOS 14.7.1 *2021-09-10, version 1.2* Are there plans to update this app? My phone won’t let me open it anymore and says the developer needs to provide an update to work on this iOS version. Thanks! ### 4/5 — Pass finder *2021-07-21, version 1.2* Still waiting for it to update to my iOS system. I love this app. I rate it highly but getting frustrating now. ### 1/5 — Not happy *2021-06-18, version 1.2* When are you developers going to update this app l use it quite often to see when the ISS is due please get it sorted ### 2/5 — Used to be good … *2021-06-10, version 1.2* Was a decent app. Recent update is broken; can’t do the update. 😕 ### 1/5 — Doesn’t work *2021-06-05, version 1.2* Get constant messages saying it needs to be updated—even immediately after updating it. Annoying and useless. ### 1/5 — Pass Finder *2021-05-13, version 1.2* This app has stopped working ….. reports update needed but it will not update Unload and reload fails too ### 1/5 — Stopped working *2021-04-08, version 1.2* This app used to work fine but has now conked out. I guess there is no more support for newer phones? ### 2/5 — Needs work. A lot of work. *2020-06-01, version 1.2* Ok, so I got the alert on my iPhone 6S. So I open the app and it’s suddenly a past event that when I click on for further info gives me nothing. A dead link. I need the inclination, compass heading etc., I get nothing. Unless I’ve had the app open already at the alert time, it’s useless. Any app is better. ## Frequently asked questions about PassFinder ### What does PassFinder do?
