Oooh so the rumors were true.

Thanks for being part of the iPhone Upgrade Program.
We're reaching out to let you know that the iPhone Upgrade Program is coming to an end. Thank you for being a loyal member. When you're ready for your next iPhone, we'll make it easy to get it in a way that works for you.

I was tricked by @benfreiband.bsky.social and @swifteves.bsky.social into not trying a Waymo at WWDC. That's not going to happen at @swiftsonicconf.bsky.social in November!

Mine was this crazy breakfast. Not only was it the first time that Bluesky power user @mattheaney23.bsky.social would speak to me, but it was also hilarious seeing him and @charliemchapman.com discover what a "breakfast pizza" was.

Charlie and Matt each point to their plate, which contains a giant "breakfast pizza". It's a flatbread with 4 sunny side up eggs.

It should be studied how much they ruined the Google Nest Hub.

Photo of a blog post that says this: This is the one that really blew my mind. Previously I could say “How long to [destination]” and it would bring up a Google Maps interface showing the route and give me an estimate based on the current traffic. I made use of this a lot. When I did the same thing with Gemini there was no map shown. It was just a wall of text. I also got the impression that it was making an estimate based on historical data and not the current traffic situation. Asking for clarification confirmed that:

"That’s a great question about how things have changed. As a conversational Al, Gemini for Home doesn’t directly access or display real-time traffic maps like Google Assistant might have done on certain devices. However, I can still give you up-to-date traffic information if you need it. Would"

I did some testing and asked it how long it would take me to get to a destination. It confidently told me 36-37 minutes. I looked at both Apple Maps and Google Maps on my iPhone and they both reported around 25 minutes.

I've had one bad thing after another happen to me in the last year but I finally have an indication that things are turning around. I just found a $1 certificate towards admission to the Catwoman movie.

A certificate from Hollywood Movie Money for $1.00 towards entry to the Catwoman movie in July 2004 with an expiration date of August 2004.

I'm really pleased with today's update to What's My Set. I always want to make things that are silly AND useful. Today I'm adding rest timer themes. A little silliness before your next set.

@cabel.panic.com Cabel you probably already know this, but Playdate spotting. One of the guys that maintains Big Ben uses a Playdate to help him. Nat Geo show called Best of the World with Antonin Porowski.

15 years ago I was lucky enough to see Sade live. It was the most I had ever paid for a concert so I could get great seats. Still one of my all time favorite concerts and someone that I never though I would get to see perform. She hasn't toured since!

Forget me being excited about Coin Drop being back. Silly me thinking that paying to remove ads meant that I had unlocked the full game. Here I can't keep playing unless I buy more lives or wait a certain amount of time. 🤮

Coin Drop screenshot that says "Purchase lives. Hey, why don't you but 5 additional lives now!" There are two buttons: Nope and $2.99.

Chris Wu 🪐@chriswu· Jul 11

I was feeling super nostalgic for old iOS games that I can't play any more. Decided on a whim to search for some and my first attempt got a hit. Coin Drop got relaunched. 🤯 Love seeing the ancient iPhone in the tutorial.

Thank you so much @hiro.report for this nice mention of What's My Set in this week's Hiro Report! www.hiro.report/05jul2026-bi...

🏋🏼‍♂️ What’s My Set for iOS - I’ve got a deep appreciation for health apps and indie-developed apps, so when Chris Wu reached out to let me know about his new set tracker app for the iPhone and Apple Watch, I was more than happy to take him up on his kind offer of a trial. It’s a simple, but thoughtful, app designed to help you keep track of how much you’re lifting, how many reps and sets you’re doing, and how much time is left in your rest before it’s time to start the next set. It also supports Tabata and EMOM-style workouts for the functional fitness crowd.

Chris Wu 🪐@chriswu· Jul 4

During WWDC I got some great design feedback that What's My Set wasn't using the available space well in landscape mode. Addressing that now!

Side by side shots of What's My Set running in landscape mode during an active workout. In the top version the set and exercise count sections have a lot of wasted whitespace. In the bottom version things are much more compact because the workout time and a pause button have been move to the right of them.

Sanity-saving use of AI: Have it resize the screenshots for reviewers that App Store Connect requires you to attach so that they meet whatever criteria are needed. No more rejected image uploads for confusing reasons.

Good news: I was charting yesterday on the Mac App Store. Bad news: I didn't remember that Mac compatibility was enabled and never tested it. The app crashed at launch on Mac. 😬 @ikenndac.bsky.social and @mergesort.me got me sorted and I'm in expedited review right now.

Nothing I do to promote my new app will ever top a poster of it hanging in an office window in Osaka thanks to @chrislindsay.bsky.social .

Well, after months of work What's My Set is finally out today. It's the workout app I always wanted and I honestly love using it. I hope some other people do as well! apps.apple.com/us/app/whats...

I assumed the animated album artwork in Apple Music would only be for new releases. 😳

As a certified dark mode hater I have been able to get away with having Xcode in light mode but the code window in a dark theme (which I strangely like). I can import the theme with Xcode 27 but it makes the WHOLE interface dark even though the config window correctly uses light mode. FB23456652

The Xcode 26 interface. All sections except the code window are in light mode while the code itself is in dark colors with a black background.

The map is enormous (Red Dead Redemption 2 size), varied, and packed with interesting content to keep finding. The developers keep patching it at an obscenely quick rate to get rid of things that are annoying and making things more streamlined.

I am still completely captivated by Crimson Desert. Even with all the time I’ve sunk into it, there’s still so much of the map that is unexplored. I thought the exploring would be fun, but the boss fights would be miserable. They actually are quite fair and the game gives you ways to handle them.

This is why there are limits to how much you can proofread your work. For who knows how long my timer descriptions have been displaying my String Catalog keys and I DID NOT NOTICE. 🤦🏻‍♂️ Thank you @ryanlintott.bsky.social !

The timer selection screen from What's My Set. The descriptions for rest, Tabata, and EMOM timers read as TIMER_DESCR_REST (as an example).

As someone who spent the first few years of their iOS dev experience working on a museum app it still feels odd to be developing apps that I genuinely use in my day to day life.

The Apple Health app reporting that I burned 195 calories during a traditional strength training workout that was 46 minutes long. It was logged via my app, What's My Set.

Chris Wu 🪐@chriswu· Jun 20

If I'm just attaching an image to show App Review what my paywall looks like why are the dimensions still strictly enforced? This bites me every time. App Store screenshots viewed by millions of people - I get it. A screenshot for a reviewer - I do not get it.

An error message that reads: "The dimensions of one or more screenshots are wrong."

Chris Wu 🪐@chriswu· Jun 20

I use the double tap gesture multiple times a week every week on my Apple Watch. I have been working out with my new app (What's My Set) on my Apple Watch for months testing it. It never ONCE occurred to me that I should add double tap support. 🤦🏻‍♂️🤦🏻‍♂️🤦🏻‍♂️ The good news it was ridiculously easy to do so.

Chris Wu 🪐@chriswu· Jun 19

My first press coverage for What's My Set thanks to @darylbaxter.com and Springboard. 🥹 Thank you so much Daryl.

I do a bunch of strength workouts every week, and sometimes it can be a challenge to keep track of the reps and sets I do. Granted, I can do it on Apple Watch via the Fitness app, but it gives you the impression of wanting to compete with yourself, when I only want to keep track of what I'm doing. This is where What's My Set comes in, developed by Chris Wu, one of the organisers of CommunityKit.

Available on iPhone, iPad, and Apple Watch for free on June 29, with a Pro subscription for $0.99 / £0.99 a month or $9.99 / £7.99 a year, What's My Set does what it's called - keeps track of the sets you're doing. At home, I've been using the app on my iPad with the four strength workouts I do, keeping track of the sets so I stick to the consistency every time. I really like the user interface, keeping it simple with easy-to-see buttons to press when you're deep in the reps. To note: just before this went live, Wu got in touch to say he used Claude Code to help him develop this. He wrote a post in February about his use of it. Sometimes the best apps keep it simple whilst solving an issue - What's My Set is a fantastic example of that.

We've already established that I'm an introvert but I was putting in WORK in Cupertino. I had only told a tiny number of people online at this point so these pre-order numbers were almost all me asking people to help out in person. I was absolutely shameless and outperformed indie fair day. 🤯

A graph showing pre-orders from June 7 to June 14. The biggest spike is on June 7, which had 32 pre-orders. The day after it falls a little bit and then June 10 is the next biggest day.

Chris Wu 🪐@chriswu· Jun 17

My advice to introverts who have an interest in the @communitykit.social Indie Fair? Recruit an extrovert! Bluesky power user @mattheaney23.bsky.social came in clutch and took over after an hour when my voice started going out again. And @joe.inkle.co can verify that I am indeed an introvert.

I recently updated to Tahoe and I've gone from almost never hearing the fans on my M1 Pro to hearing them all the time. It seems to be AMPArtworkAgent taking up a big chunk of the CPU and quitting Apple Music stops it.
