Here’s a really impressive freebie just released by UI8.
MNML is probably the biggest mobile UI kit we have ever seen, made of 176 beautifully designed mobile screens and ranging over 11 different categories.
The best part? It’s completely free to download and 100% made with Adobe XD.
You can see a full preview on their MNML product page. Just click on the download link to access the XD version, which at the moment is still not well advertised (the page still says it’s only for Sketch).
