New in Weathergraph: world-class rain predictions from Rainbow.ai, using radar data and ML.
I stress-tested it on a 3-week Balkans road trip, and yes, it’s good. So good I added the nowcast chart right into your Home Screen widgets to put it front and center.

Phew, I might be able to run Apple's latest on-device models. #wwdc
(And that's MacVitals, my better memory manager app macvitals.app)

I really like iOS 26 SP1, I mean 27 beta.
Faster than 26 on day one, and have yet to encounter a bug.

Hi! ¡Hola! Ahoj! Buongiorno! Bonjour! 안녕하세요! 你好! 👋
Weathergraph now speaks 10 languages — every screen, every forecast, every rain alert.
Which one’s yours

Weathergraph for Garmin got a huge summer refresh for OLED screens. Let your summer be colorful!

Just wanted to say that Weathergraph:
- has no ads or tracking code
- rounds coordinates so weather providers don’t get your exact house/block
- aggregates and proxies requests, so providers can’t track anyone’s movement by IP
I like privacy.

BREAKING: You checked the weather this morning.
And you just told a surveillance company where you sleep.
Meet #Webloc, used by ICE, cops & foreign govs to track 500m phones.

David asked me to make the bottom toolbar collapsible on scroll to really let the content shine, and I took that as a challenge to go all in on physically driven interruptible animations like Safari does.
The next update is gonna be 💯

Arthur Brassart is a go-to guy for Apple Watch app recommendations, so I'm super glad to have made it to the center of his daily watchface.

Bet you won’t guess what’s my next watch app - I turned the old Garmin with broken lugs into daily chore organizer for my kids (they switch them on even/odd days to minimize “that’s not fair!” :)).
(There is a magnet with a double sided tape on the back for easy charging)

A link and “official” screenshot - it’s called Daily Chores in Garmin store.

I made an app that turns a Garmin watch into a daily chore organizer for two kids! 🧹⌚
Rotating tasks swap automatically between two kids every day - no more "it's not my turn!" arguments.
Using it on a broken Forerunner 45 stuck to the fridge.

Remember Weathergraph started on Pebble (and still runs there)? This has to be one of the coolest uses I have seen so far.

It is now also a perfect time to enable rain alerts ⚡️☔️
The update just got approved in the App Store, here’s the link:

When I loaded the latest podcast into the watch for an evening run, I didn’t expect to shed a tear and run the 2nd half in silence.
Thank you, @marcoarment and @_DavidSmith, your duet definitely didn’t fly under the radar.
Looking forward to whatever you made space for!

I realized that colorful widgets on glass are possible with a neat trick (coming up in @weathergraph as soon as final iOS 26 releases).
Which ones would you pick?

To be honest, the readability heavily depends on a wallpaper - here are same screens with a lighter and more contrasty one.
That's why I will keep it as a per-widget option.

Super proud that after all these years, @weathergraph still runs on the @ericmigi @Pebble - and is the only watchface present twice in the screenshot collage of the Pebble 2 rebirth blogpost 🤩.
Link below for everyone who loves a lightweight watch with 4 weeks battery life.
