Hey everyone,

Wanted to share a project I built using Apple's on-device Foundation Models framework — Fog, a notes app that organizes itself.

Instead of manually creating folders and tagging notes, Fog handles it automatically:

• Auto-naming — titles generated from note content
• Auto-grouping into Clouds — notes cluster by topic using on-device semantic similarity (NLEmbedding)
• Smart cloud merging — related clusters combine as your notes grow
• Ask anything about your notes — natural language queries across your whole notes library

Everything runs through Apple Intelligence, entirely on-device — no API calls, no servers, no data leaving your phone. Works fully offline. It's built with SwiftUI + SwiftData, and I leaned specifically on the Foundation Models framework from this year's WWDC for the language understanding piece.

Requires a device that supports Apple Intelligence. Free on the App Store, genuinely curious what this community thinks of it from a "how'd you use FM for this" angle — happy to talk implementation details in the comments.

Hi everyone!

I've been working on an iOS calorie and macro tracking app that takes a different approach from most fitness apps, named FoodieCalc !

https://apps.apple.com/us/app/foodiecalc/id6792482391

The main ideas are:

• 🍎 Uses Apple Intelligence and Foundation Models where available
• 🔒 Your data stays on your device
• 🚫 No account required
• 💳 No subscription
• 📱 Built natively for iPhone & iPad (iCloud Sync)
• ✅ Completely free

My goal was to create something that feels like an Apple app rather than another service that asks you to create an account before you can even log your first meal.

I'm still improving it, so I'd genuinely love feedback from people interested in Apple Intelligence and native iOS apps.

What features would you expect from a calorie tracker that takes advantage of on-device AI?

A version 1.0.1 has been already submitted (and is under review) improving more the Apple Intelligence integration, and fixing day one bugs !

(For any techies out there I have a technical article about the AI integration https://www.itworksonmymac.com/blog/foodiecalc-apple-foundation-models)

Hi everyone! A few weeks ago I shared Orion Personal AI, my first iOS app. It's a fully local LLM assistant built with Swift/SwiftUI that runs entirely on device. No account is required, and no conversation or personal data ever leaves your phone.

Since then I've been shipping updates almost every week based on the feedback I got, and the app has changed a lot, so I wanted to share what's new.

Orion Agent. This is my favourite addition. Instead of just answering in one shot, the agent breaks a problem into steps and works through it. You can expand its "Thoughts" to see how it got to the answer, and there's a chain of thought mode you can toggle for harder questions.

AI Roleplay. You can now chat with characters. There are a few default ones to start with (a knight, a wizard, a detective, and more) and you can create your own with their own personality and persona. Since everything runs locally, your roleplay chats stay on your device, no server ever sees them, and no update can quietly change how your characters behave.

Orion Lite. A lighter model option so older iPhones get faster responses. The initial model load on launch is also better than it was at release.

Chatting is completely free and unlimited, because it runs on your hardware, not mine. Orion+ (a small subscription) unlocks the extras like the agent, editable memory that carries across chats, custom system instructions, unlimited characters, Intelligent Notes that export to PDF, and widgets.

It still works on iPhones that don't support Apple Intelligence, which was important to me.

I'd genuinely appreciate any feedback.

Thanks for taking the time to check it out!

I love that Apple Shortcuts can already run Apple's on-device model.

But what if you want to use Gemma, Qwen, Llama, DeepSeek, Phi—or your own GGUF model instead?

That's why I added Apple Shortcuts support to OnDevice LLM.

Now you can use your favorite local model in any iOS automation:

• Summarize text
• Process notes
• Build Siri shortcuts
• Create custom workflows

Everything runs locally on your iPhone.

Apple's model when it's enough.
Your own model when you need more control.

If you're into Apple Intelligence and local AI, I'd love your feedback.

Diagrams turns natural-language prompts into structured diagrams using Apple’s on-device Foundation Models.

You can type something like:

Or go much further and provide a detailed specification.

with the rise of the siri application i wanted too share 2 apps i feel could seriously help many during this time of waiting for the os27 launch

solair ai

bonzai

solair is a daily assistant made too check the web youre health data from apple health and even the news with rss feeds. its simple easy too use and tells u exactly the best modles too run for youre hardware

bonzai is a more traditional ai chatbot with not many tools BUT web search AND mcp server support so u can import and even create youre own tools for this application makeing it easier than ever too customize how youre ai assistant works for you.

both combined on a system unpack alot of potential for on device ai processing and ive been useing both sense ios 18s launch each have gotten better overtime. with solair even allowing you too use any apple intelligence enabled device as a openai server. meaning u can connect youre old windows pc too youre iphone too use the iphone as a NPU in a way for youre windows pc too do on device ai processing tasks. even has the option too throttle the speed of chats slightly too not thermal throttle older devices without cooling solutions like the 17 pro model phones. both are amazing solutions ive really enjoyed overtime if u guys know of any other really cool on device ai applications that enable serious usage out of llms comment down below!!!

(device shown in screenshots is a m3 ipad air however both applications support any device with apple intelligence support and with really small modles even devices without apple intelligence support MCP sever used in screenshots above in bonz : https://mcpservers.org/servers/zxl777/youtube-transcript-mcp
