Just send BreathInU to review!
New version is including more Siri and Widget integration, so users can access their favorite exercises easily.
The app is also compatible with the Duo, maybe some day I will see it live on a device

If you are creating an app, don’t forget to localize it! I see so many great apps losing opportunities because of this.

Daily App Store tip:
App Review takes time, and it’s not always easy to plan around.
Don’t leave your submission until the last minute if you have a deadline.

Daily App Store tip:
Ask happy users for reviews.
Reviews help potential users understand your app and can improve your App Store presence.
Just make sure you ask at the right moment.

More Siri AI integration is coming soon on Ventilate and BreathInU!
To make it even better, the same actions will be available through widgets!

All I can say about the new DR4 algorithm: I don’t want to look at how my website are changing 🥺
Please don’t make me look.

Daily App Store tip:
Before submitting your app, let someone else use it.
TestFlight is perfect for this.
You know your app too well. A new user will find things you never noticed.

Daily App Store tip:
Using third-party SDKs?
Explain what each one does in your Review Notes and why your app uses it.
It takes a few minutes and can prevent unnecessary questions during review.

Challenge before the end of the year: revive the website breathinu.app !
It has been live for a while but almost no traffic. Let’s change that 💪

Super sad to see another conference go. FrenchKit, now known as Swift Connection, stops after 10 editions.
Conferences are more than tech: they make connections. I truly hope we’ll keep many of the other events 🙏🏻
Daily App Store tip:
Your Review Notes are not a formality.
Think of them as a mini user manual for the reviewer.
Tell them what to test, where to go and anything they need to know.

Las olas de calor urbanas dejan la noche más caliente que el campo. El asfalto suelta el día después del atardecer, y la ventilación nocturna empieza más tarde.

Daily App Store tip:
Don’t bury your Privacy Policy and Terms of Use.
I always keep both links easy to find at the end of the App Store description.
Tiny detail, easy to forget.

Autumn rain changes when to open your windows. Close before the shower, keep the blinds open for daylight, and air your home in the dry spells.
Ventilate reads clouds and rain.

My biggest lesson after 10 years of shipping apps:
The technical work is only part of releasing an app.
You also need to understand review, distribution, marketing and your users.
And I’m still learning every day, so follow me to discover what I do!

Daily App Store tip:
App approval is not the finish line.
Once your update is live, watch what happens.
Crashes.
Reviews.
Usage.
Retention.
Feedback.
That’s where the next iteration starts.

If you have an Apple developer account or an app in the App Store, read this now and share it.
Apple rejects your app. The notice is vague, so you fix what you reasonably think is wrong and resubmit.
Apple approves it.
Months later, with nothing in review, Apple terminates your account under 3.2(f) for “a pattern of manipulative or misleading behavior.” Every app gone. No explanation of what you did.
Your crime? Trusting the approval.
Apple’s own reviewer looked at your fix, with your rejection history in front of them, and said yes. Then Apple turned that yes into evidence against you.
So who’s misleading whom?
I ran App Review for seven years and wrote the guidelines. 3.2(f) used to mean real fraud. Now it’s being used against developers who did exactly what Apple approved.
I’ve made this Substack post free for everyone. Every developer needs to see it before this happens to them.
Share it before someone you know gets that email.

Daily App Store tip:
Don’t wait until your app is approved to start marketing it.
Build your audience while you build the app.
By launch day, you want people who are already curious about it.

Daily App Store tip:
Product Page Optimization and Custom Product Pages are not the same thing.
PPO helps you test versions of your default product page.
CPPs let you create tailored pages for specific audiences or campaigns.

I don’t think people realize how selfless and wonderful the StackOverflow’s founders were.
Unlike reddit, x etc they insisted ALL of their content will be 100% open, nothing will ever be locked up in walled garden.
They made it a point by even offering structured data downloads!
They didn’t cared people cloning the website. They didn’t worry about putting the whole monetization thing at risk.
It was a true hacker spirit in it’s purest form.
Most folks won’t be able to grasp how hard this is. You are on top of the world. Millions of people depend on you daily. You have the rarest opportunity to rack in billions. And you still stay true to your principles.
This exactly in turn later enabled AI revolution. I still remember downloading entire SO archives and preparing it for pre-training while Reddit and others went onto lawfare and firewalling the content. Note that this was the content their users - not reddit employees - had created for free and voluntarily to help others and the world. But they locked it all up for profiting from it personally.
SO did none of that. I think they knew they will be sacrificed at the altar. Yet it will exactly serve the intent of their founding principles to help others and the world, now through AI, even at bigger scale.
All of today’s models are built upon efforts of such true pure hackers who spent their days and years to create training data for AIs. I was a proud SO contributer for many years and there are couple of times while testing models I did felt that models might have used my answers 😇.
Hats off to @codinghorror and @spolsky and so many builders and hackers at SO for moving the world forward, one revolution at a time 🫡.
