Some personal news: this month marks 10 years since I first started developing Delta!

So much has changed since then, but I couldn’t be more thankful to still be working on it after all this time 💜

So please enjoy this “10-year anniversary” update, and here’s to another decade of Delta 🥳

We’re also:
💰 Donating $500,000 to various Fediverse-related projects
🌏 Launching PAL in several more countries this year
👥 Expanding the team!

Evolving AltStore PAL

Between expanding worldwide and adding Fediverse integration, the next year will be an incredibly exciting time for AltStore!

While this solves our problems, we're far from the only Fediverse project in need of funding and we want to support the growth of the entire ecosystem.

So to give back to the open social web, we’re also donating $500,000 to various Fediverse projects 🎉

For a complete list, check out our blog post!

Additionally, Flipboard CEO @mmccue.bsky.social will also be joining our Board of Directors!

Mike’s experience with Flipboard & @surf.social will be invaluable as we expand to the Fediverse, and I couldn’t be happier to have both him and Chris on board

Riley Testut @riley.social · 1d

So in order to grow the team, I’m thrilled to announce AltStore has received an investment of $6 million USD from Chris Paik at Pace Capital!

Chris was an early investor in Patreon and Twitch, and we’ve been close ever since he sideloaded the manga reader Paperback with AltStore Classic years ago

Riley Testut @riley.social · 1d

To get this all done however, we realized we needed more help.

From the beginning it’s been just @shanegillio.bsky.social and I working on everything thanks to donations to our Patreon, but the truth is we’re starting to reach the limit of what just 2 people can do

Riley Testut @riley.social · 1d

That's not all, we'll also be officially launching AltStore PAL in Brazil, Japan, and Australia later this year, with UK to follow in 2026 🌏

This is the first time alternative app marketplaces will be available outside the EU and we are doing everything we can to get ready — stay tuned!

Riley Testut @riley.social · 1d

Yes it's true, AltStore is joining the Fediverse 🥳

Developers can now federate apps, updates, and news alerts to the open social web via our custom Mastodon server!

We plan to release this natively in AltStore soon — but you can check out a beta version TODAY at explore.alt.store

ICEBlock Official @iceblock.app · 6d

We just received a message from Apple's App Review that #ICEBlock has been removed from the App Store due to "objectionable content". The only thing we can imagine is this is due to pressure from the Trump Admin.

We have responded and we'll fight this! #resist

Riley Testut @riley.social · 12d

if only they could keep their App Store clean and pristine while allowing others to install the apps they wanted some other way!

wish there was a term for that 🤪

Riley Testut @riley.social · 12d

oh I’m sure they know, they just also know most people don’t and use that to their advantage 😂

(to be fair tho that’s smart on their part, so I don’t blame them)

Riley Testut @riley.social · 12d

I don’t disagree, except apps distributed through AltStore (and other 3rd party stores) actually use App Store Connect and have the same age rating system, so parental controls already do work with them!

which makes the whole thing even more ridiculous 🙃

Riley Testut @riley.social · 13d

IMO if Apple’s worst, most egregious example of a harmful and dangerous app that’s now available through sideloading is *checks notes* porn…I think we’re doing OK www.apple.com/newsroom/202...

Excerpt from Apple newsroom post about DMA:

• New exposure to harmful apps: For the
first time, pornography apps are available
on iPhone from other marketplaces —
apps we've never allowed on the App
Store because of the risks they create,
especially for children. That includes Hot
Tub, a pornography app that was
announced by AltStore earlier this year.
The DMA has also brought gambling apps
to iPhone in regions where they are
prohibited by law.

had to test it out in a LIVE setting 😄

Riley Testut @riley.social · Jun 26

A beta is available now for Patrons to test out, and I’m hoping to release it later this year for everyone!

Of course like all my other apps it is entirely open-source, so devs feel free to just compile it yourself 🛠️ github.com/rileytestut/...

Excited to finally announce my upcoming app — Delta Camera! Before making iPhone emulators I made camera apps, so it was fun to combine my 2 passions into a single app :)

My personal favorite feature: full Camera Control support 📸
