What it does
Jump in free with 60 A/B design challenges, zero credit card required. Two designs. One is better. Can you spot why? SpotTheUI trains your design eye through rapid-fire comparisons across 12 core principles like visual hierarchy, spacing, typography, and color. Four difficulty tiers take you from beginner fundamentals to expert-level details that most designers miss. With 480 challenges total, this isn't a course you watch, it's a gym for your design intuition. Start training your eye today.
Master design principles through 480+ interactive A/B challenges. Train your eye to spot what great designers see. Start free with 60 challenges, unlock all for $9.99.
Most design skills are taught through theory. SpotTheUI teaches through practice. Fast A/B challenges that train your eye to see what great designers see. Each challenge takes about 30 seconds. Before you know it, you'll have trained your eye on dozens of real design decisions. Every challenge presents two UI mockups. Both look professional, but one follows the design principle better. Trust your instinct. Tap the design you think is stronger. Easy at first, then deceptively tricky. Get a clear, concise explanation of what makes the better design work. This is where real learning happens. No videos to watch. No articles to read. SpotTheUI is pure practice, the part most learning tools skip.…from spottheui.com

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
