I use an app called ACNH.Guide which has been very helpful in keeping track. Not sure if it’s on android, but it is on iOS. You can keep track of your catalogue, reactions, DIY, etc.
The DIY section is a little weird though, it doesn’t just count if you have the DIY, but if you made it as well. My app says 919/1828 DIY, but I don’t keep track of what I craft so it’s actually 919/924 if that makes sense.
For a long time I thought there were 914 DIY, since 1828/2=914, however for some reason 10 DIY don’t have an option to say you crafted them.
It’s a very useful app, the way it counts is just confusing. I suggest not cataloging if you’ve made something or not, and just to remember that 924 is the actual number you’re going for.
