You can now run SDXL locally on your iPhone
Generation time in @PhoneDiffusion is <10 seconds

Choose between:
∙ DreamShaperXL

It’s mind-blowing how capable the base iPhone 16 and 17 are nowadays.

You can now run SDXL models locally on your iPhone!

Choose between DreamShaperXL, RealVisXL and VegaRT (experimental)

Any guesses on the generation time? 👀

[Rok Gregorič @rokgregoric]

So you are asking users to signup on web?

How do they trust they’ll get access to the app?

[Adam Lyttle @adamlyttleapps]

Conversions have bumped up to 2%

There is an A/B test I'm running on the paywall:

A)
Headline direct: "Your kid will learn a new skill"

B)
Headline emotive: "Give the gift of learning a new skill to your kids"

B is winning but still too early to call.

Currently only 50% of people see version B. Which contributed to the bump in conversions.

Waiting for full results to come in before making a call. But excited for this test.

[Rok Gregorič @rokgregoric]

Would love to hear more.

[Rok Gregorič @rokgregoric]

Lots of them! Good times!

[Viktor Seraleev @seraleev]

Did you ever ship an app written in Objective-C?

Dinosaur roll call 😁

12 years ago today, Apple introduced Swift

[Rok Bozic @rokbozi]

We just achieved 3sec image generations running Stable Diffusion locally on a base iPhone 17 🤯

SOTA benchmark dropping tomorrow @PhoneDiffusion

Comment for the benchmark & download link ↓

[Rok Gregorič @rokgregoric]

@seraleev Best of luck, inspiring story!

[Rok Gregorič @rokgregoric]

You can bundle them together in one submission!

[Viktor Seraleev @seraleev]

Today I learned that App Store Review has submission limits:

1. Submitted an app update ✅
2. Submitted a Custom Product Page ✅
3. Tried to submit an In-App Event ❌

“Maximum number of submissions allowed in review.”

Apparently even Apple wants me to slow down.

[Rok Gregorič @rokgregoric]

Haha, happened to me and @adamlyttleapps as well.

It’s not us, it’s bad UI!

It should not be possible to do that IMO.

[Engin Kurutepe @ekurutepe]

So, I did the noob mistake, took a new app version online before the new IAPs were approved.

Don't be like Engin, don't release your app updates before the necessary IAPs are approved.

[Rok Gregorič @rokgregoric]

@matteo_spada Haha, good one!

[Rok Gregorič @rokgregoric]

@david_attisaas Please do!

[Rok Gregorič @rokgregoric]

@seraleev If you’re young at heart, wrinkles don’t matter.

[Rok Gregorič @rokgregoric]

@ekurutepe Metallica fan?

[Engin Kurutepe @ekurutepe]

I made a Codex port of @adamlyttleapps's Claude ASO screenshots skill. It's the same except this one uses the built-in OpenAI image generation skill instead of Nano Banana. No need for a separate API key. https://t.co/8zrBTzxTIw

[Rok Gregorič @rokgregoric]

@PhoneDiffusion Wow!!!!

[Rok Gregorič @rokgregoric]

Agreed! Codex XH is doing an amazing job. Developing new features and fixing issues in one shot! 👏@sama

[Siqi Chen @blader]

nothing like switching to claude for a few days to try out a new model and going back to codex xhigh to remind you how much better 5.5 is right now

it's really not close

[Rok Gregorič @rokgregoric]

Shameless plug.

[Ariel from Appfigures @arielmichaeli]

@seraleev Unpopular opinion - take the $100k. Invest 40% in stocks and use the rest to kickstart your next app.

[Rok Gregorič @rokgregoric]

They don’t like Java either 🤣

[Ariel from Appfigures @arielmichaeli]

@rokgregoric 😂
