New Studio site sneak peek 👀 (dropping soon) From custom 3D scenes by @krysjezek to spatial pinning using Motion & Orientation Access in Safari (yes, this whole thing is a website), Custom Glass shaders, progressive blurs, device screen overlays using video data and so much more… Can’t wait for all of you to try live 🚀

Just… hire a designer 🤔 Anyhow, struggling with the same? Luckily I run a design studio and we specialize in making delightful and beautiful apps. Time to switch from slop to intentional.
Is there a simple design tool/skill/mcp that’s specifically trained on great iOS UI design patterns? I’m still really struggling with UI in my latest vibe coded app. I’m probably throwing too much at the wall with both @mobbin and @referodesign connected to Claude Code. I think part of the problem is garbage in garbage out. Those tools mostly just surface patterns from popular apps. But just because an app is successful doesn’t mean the UI is great.

Apple is removing AI slop. Get your app actually done by human designers, hit me up at [email protected] ✌️
Couldn’t ignore what’s been happening in the iOS developer world lately: rejections, long review delays and developer accounts being shut down. What’s going on, and what can we do about it? I wrote down my thoughts and some practical steps to take.

Glad to see @runmoapp being ahead of 92% of apps already. I truly believe the late nights and weekends polishing the smallest details pay off. Today’s edge is design (visual, interactive, brand, product), AI sped up things, but flooded market with tasteless “make millions” false promise slop. You have no idea what I’m working on now, next months of releases will be packed. @Strava @runna coming for you! 👀
We all need to read this - I love the laid out facts and where we are today

Locked in last week. @runmoapp is ready for Duo. Straight from the App Store Connect, including header images in 3 localizations. 😮‍💨 Waiting for review 🚀

This video can save you 10s of hours a week 👀 TLDR; creating localized mockups in multiple variants and display sizes for A/B testing on App Store ads, automated (but not AI generated ✌️) I’ve struggled with keeping @runmoapp screenshots up to date. We’re releasing updates weekly, like big ones that change key screens regularly / add substantial features. We use amazing mockups by @lstoregraphics and I had to open the pre-release build, take screenshots on my device, place them in the mockups using a @figma plugin, then place them into the template, scale to different sizes and duplicate per locale. Don’t even get me started on “what if we swapped this screen for that one” or “how about a new test set” = design * by number of sizes (can’t wait for Duo 🙃) * locale. Tens of hours. Weekly. And that’s not even counting we have to keep web assets up to date as well + web release notes screenshots (yes, we have those too). Today, all that is automated. When Development merges to release, @ClaudeDevs (Claude Code) runs a custom xcbuild simulator with a pre-set profile (regular runner, Prague for metric system, NYC for imperial, my profile pic etc.), takes screenshots (and videos!), calls a local tool that uses the mockups, updates App Store Screenshots (all locale and variants), updates website mockups and release notes. All while letting me preview the screenshots as they Appear in the App Store and reuse mockups and my designs so I can create new test sets for @AppStore search ads 🚀 @figma + @claudeai > Local Internal mini-tools are the future. Already have dozens of others (ehm ehm @zoink if you read this and find it cool maybe we can like chat about AI in Figma) saving me so much time I can focus on pure design only ❤️

Short on time today. Here’s a peek 👀 interaction for agentic computer use. Any site > wireframe Peek to see the actual content, nut just highlights.

Behind the scenes of @runmoapp’s Coach. I wanted a simple pictogram that feels familiar, kinda like the Apple’s Face ID glyph, portraying a sideview of a coach face with a cap. There’s plenty of little details, like onload spin animation, blinking from time to time and reading 👀

This is how I create effects for @runmoapp by the way 👀 I let @claudeai create a little tool with sliders where I can play with my intention. Always using Metal shaders for interesting effects and getting the most out of the GPU. I know the UI is gimmicky and all, but this is how I make things feel just right, fast. This is the early version of today’s coach in app ✌️

One of the early explorations in @runmoapp for Coach using custom Metal shader Aurora Borealis effect. Later replaced by what’s in the app today. But I still like the effect 👀

Experimenting with splitting combined runs interaction in @runmoapp You can actually flip by scrubbing as well. And the “arrow.up.and.line.horizontal.and.arrow.down” icon felt so satisfying 👀 What do you think?

Track Replay in @runmoapp. You can now scrub through your run or play it automatically while watching distance labels and switching between Pace, Elevation and HR along the way. ✌️
