Last year, WWDC25 inspired me to rewrite my strength-training app Reps & Sets in Swift so it could take advantage of Apple’s latest frameworks, like Foundation Models and Image Playground. It was a massive undertaking, even with the help of today’s AI-powered coding tools.
When I introduced the new version of Reps & Sets on Cult of Mac in January, it was fairly basic. The polite term is “minimum viable product.” All the core features were there, along with a slick Liquid Glass interface and iPad support. But there wasn’t much beyond that.
Many of my users are Cult of Mac readers, and you’ve had no shortage of ideas for improving the app. I’m a solo indie developer. So, over the last five months, in my spare time, I’ve been steadily implementing your ideas. Reps & Sets now includes Apple Intelligence workout summaries, Live Activities, custom exercise photography, a fully standalone Apple Watch app and much more. And it’s still completely free.




Apple revealed what it has up its sleeve for Apple Watch during its WWDC22 keynote Monday. watchOS 9 includes some fun new watch faces and various other minor additions. But the Workout app really stole the show with a host of welcome new features.
