App not working

The app is not working with latest ios. It can’t be open. Please fix the bug as we use this app to calculate the DLS score. Thank you!

App is not working on my iPhone e 15 pro

App no more opens up, it closes/crashes as soon as I open it

App not compatible with iOS17

The DLS calculator app is not working with the latest iOS 17. It simply fails to launch.
Could u plz check ?

Not intuitive

isn’t intuitive and I couldn’t get it to work.

Wonderful app.

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.

Excellent app used by SCA (Scarborough Cricket association)

Excellent app! Used by Scarborough Cricket association version g220 which Can be changed by going into "about" and entering 220 as the version

Awful usability

Buggy, and Practically impossible to use. Not worth the effort.

doesnt work

Useless or completely unintuitive. The settings button does not exist

Calculation wrong

Did not calculate the correct revised score based on today's ICC WC game NZ v SA

Works only for interruptions in the first innings

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.

A nice attempt

App is nicely laid out and is quite straight forward to use, however unfortunately due to the screen size dimensions, when using it on an iPhone 4, you can't do any calculations when there is more than one interruption.

Awesome

I needed this app today cuz we had an rain affected match today. Didn't know that there was any app. We calculated it and perfectly with our paper calculations! Thanks!

Use the D/L Pro algorithms

Unfortunately I can't use your D/L calc on my iPod touch as it is an old 2nd gen model which only supports up to iOS 4.2.1. However I can run a ZX Spectrum emulator on it and have written a program for that 30-year old home-computer which computes the D/L Pro scores, and can compute a full scrollable over-by-over par-score table as well as a selectable ball-by-ball par score table to be displayed alongside it. Being the Pro version, the G50 Value required by the Standard version is not used, meaning it works for any competition

The D/L Pro software is freely available from certain official cricket websites despite some others saying it isn't, and the algorithms it uses have been reverse-engineered and the source-code of the reverse-engineered version made available by someone else making it very easy for anyone to write a version of the D/L Pro software for pretty much any platform.

Still, your version of a D/L calc is as good as any other currently available for iOS, and has the advantage of being free so it is woth 3*. It's a pity that its calculations are likely to be a few runs off due to using an almost obsolete algorithm.

Great
