My favorite metric for a successful @launchedfm.com episode is the amount of laughter in it, and @jagcesar.bsky.social and @fosiadesign.bsky.social served those up in spades 😅 This was such a fun one!

Our apps have used CloudKit as backend since forever, but we've decided it's time to move on. We already migrated Lysten, our podcast player, and next up is Ambre. Check out our blog post for details on why CloudKit rocks, and why we're leaving it. 👇 blog.ambi.se/leaving-clou...

We've embraced agentic coding by automating the whole path from ticket to TestFlight. In practice: we create a ticket, hand it to an agent, and a few cups of coffee later the fix is live for our beta testers. Here's how we built it 👉 blog.ambi.se/agentic-tick...

How to run two Claude accounts in parallel on the same machine
If you use Claude Code (the CLI) with multiple accounts — say, one for a personal project and another for a work project — you’ve probably run into the annoyance of having to log out and back in every time you switch. Here’s a quick way to run both accounts in parallel on the same machine using direnv.

We try to reply to all App Store reviews for our apps, but the push notifications from the App Store Connect app aren't great. So I vibe coded a solution a couple of days ago, and look here. It works! 😁 I haven't read or written a single line of code.

Before image of two screenshots. One showing a feed of episodes in chronological order and a separate section "continue" for started, but not finished, episodes. The other screenshot shows episodes in the detail view of a podcast show.After image of the same two views in the before image. All episodes have a background color based of the podcast show cover art, bringing a variety of colors. Compared to the light grey background in the before. The cover art for episodes in "Continue" are much bigger and easier to identify. In the podcast detail view, each episode show their specific cover art, instead of the podcast show like before.

Has Apple Entrepreneur Camp been canceled? The former website now returns a 301 and forwards to developer.apple.com `https://developer.apple.com/entrepreneur-camp/` I was a big fan of Apple helping small companies get started. It helped @fosiadesign.bsky.social hit the ground running! 🏃‍♀️💨
