On some trips we are working in and out of the 12 mile limit, so would be good if you could select what days of the trip are, or aren’t effective based on midnight positions. ### 5/5 — Almost perfect! *2018-06-08, version 1.5.4* The app is very good in general (especially there is no any other app in the store!) but I would like to suggest to add few options such as; entering new departure date and the app will tell how many minimum days to sail (especially when spent days in the UK more than Full Days In Hand)!! ### 4/5 — Good app *2017-11-14, version 1.5.3* I like this a lot, just hurry along with the output to spreadsheet. New layout is good and a lot less glitchy, good stuff ### 1/5 — Update *2017-10-26, version 1.5.2* Update needed ASAP Cannot view data on App until iOS 11 update completed. Please help !! ### 5/5 — Needs update *2017-10-23, version 1.5.2* There are lots of us guys that use this app but it needs updated. Very good app and alot of people rely on it. Please update ### 5/5 — Great app *2017-10-20, version 1.5.2* Great app keeps all your days counted well but need the iOS 11 update ASAP ### 3/5 — Was excellent *2017-10-18, version 1.5.2* Was excellent but now not compatible with iOS 11 update and worry of 5 stars 👍 ### 5/5 — IOS11 *2017-10-18, version 1.5.2* Been in touch with the owner today 17th oct 2017. He has confirmed ios11 is coming in the next few days and apologises for the delay. He said the app WILL be compatible with iOS 11 and also said new features are also coming. ### 3/5 — Needs update!! *2017-10-13, version 1.5.2* Needs IOS 11 update, please!! ### 1/5 — Rubbish *2017-02-17, version 1.5.2* Always crashes wipe satay when crashed.
