Cheatsheets are in beta

Initially, Cheatsheets were an email-only benefit, this was mostly so I could test the reaction without building stuff.

Well, it was fantastic, and so we've now taken them, and built them natively into the site (for BFM+ members only).

Plus, you'll notice a load of quality of life improvements and bug fixes.

Built for Mars x Mobbin

Today I’m really proud to announce an exclusive partnership with the greatest UI / UX library on earth: Mobbin.

I’ve been a fan of Mobbin for years, I use Mobbin, and I recommend Mobbin to anyone who will listen.

Well, as of today, all existing and new BFM+ subscribers will get 6 months of Mobbin Pro for absolutely free—no credit card required.

You can go and redeem this right now from your BFM+ Account.

Why Mobbin?

With Built for Mars, I’m constantly trying to contextualise the ‘why’. Why do some designs work, when almost identical ones don’t. What’s the subtle nuance?

But designers also need the ‘what’, and the reason I use Mobbin personally, is because it’s such an incredible resource for references.

How to redeem: 🙌

Here’s a rundown of how you can use their massive library for inspiration.

Launching exercises (in beta)

I'm always experimenting (and speaking to BFM+ members) about how to make the analysis both more actionable, and interactive.

That's why today we've launched exercises: a way to embed questions, practices and challenges inside of casxe studies, UX Bites, the UX glossary and more.

A few key points:

  • You'll be able to track you streaks throughout the entire site, across multiple sessions.
  • You can always see your best ever streak in your account.
  • Questions can be single-answer, or multiple choice.

Consider this as a beta (for now), because I'm still experimenting and learning which questions and types of quiz are the most interesting.
