Here are a couple of Animal Crossing tools and sites that I have found useful:
- Turnip Prophet: If you are not opposed to mild cheating in the form of data mining, someone reversed engineered the turnip market information. There are several calculators available, but I like the interface and charts on this one the best.
- Animal Crossing Pattern Tool: You can use this to convert images to Animal Crossing QR Codes. You will need to have an active Nintendo Online membership and the phone app to use your patterns in New Horizons.
- Island Tune Creator: Easy way to create island tunes.
- Nookpedia: One of several Animal Crossing wikis. I use Nookpedia because it gives gift suggestions for the villagers.
- Nook Plaza: New Horizons item database. It’s one of the only ones (that I have seen) that shows what the customization options for each item look like.
