During the lockdown me and my partner got into crosswords and codewords, and with my partners first language not being English, and me mostly failing English in school I built this little web app to help us find potential solutions for crosswords.
I built this simple app because 1) I didn't want to install an app, and 2) a lot of the sites on the Web are laden with junk adverts or complex syntax. I just wanted something simple to use and that loaded instantly.
To use the app, you just include all the letters you know and use _ or . for the letters that you don't know (i.e, CA___A). If you know there are two letters that will be the same but you don't know what they are you can use a digit (i.e, B12121).
I will do a technical write up soon, but it's a pretty traditional PWA.
