It can’t be open. Please fix the bug as we use this app to calculate the DLS score. Thank you! ### 3/5 — App is not working on my iPhone e 15 pro *2024-01-07* App no more opens up, it closes/crashes as soon as I open it ### 3/5 — App not compatible with iOS17 *2023-10-13, version 2.1* The DLS calculator app is not working with the latest iOS 17. It simply fails to launch. Could u plz check ? ### 1/5 — Not intuitive *2019-04-22, version 2.1* isn’t intuitive and I couldn’t get it to work. ### 4/5 — Wonderful app. *2018-09-04, version 2.1* Thank you so much for creating this app. There is a very small problem I found with Par score. When you select overs lost as 0.0, the calculate button produces par score which is exactly equal to Target score. It should be one less than the target score (that is, target score - 1). Rest is all fine. It is a really good app. ### 5/5 — Excellent app used by SCA (Scarborough Cricket association) *2018-06-24, version 2.1* Excellent app! Used by Scarborough Cricket association version g220 which Can be changed by going into "about" and entering 220 as the version ### 1/5 — Awful usability *2018-04-11, version 2.1* Buggy, and Practically impossible to use. Not worth the effort. ### 1/5 — doesnt work *2017-10-29, version 2.1* Useless or completely unintuitive. The settings button does not exist ### 1/5 — Calculation wrong *2015-03-24, version 2.0* Did not calculate the correct revised score based on today's ICC WC game NZ v SA ### 2/5 — Works only for interruptions in the first innings *2015-01-18* I checked this against the examples in the appendix to the book by Duckworth and Lewis, and got correct results only for the cases in which the only interruption was in the first innings. This is better than one of the competing apps that was literally never right, but that's not saying a lot. ## Frequently asked questions about Duckworth ### What is the Duckworth-Lewis Calculator used for?
