AFM Sandbox is a free learning app for Apple’s Foundation Models framework. Everything runs on your iPhone or iPad. There is no account and no server.
Questions, bugs, or App Store review notes can go to henryisobe@gmail.com. Please include your device model and iOS or iPadOS version.
Email supportAFM Sandbox needs a device that supports Apple Intelligence, running iOS 27 or iPadOS 27 or later, with Apple Intelligence turned on and the on-device model downloaded.
Apple Intelligence is off, still downloading, or this device does not support it. Open My Device in the app to see the variant, context size, and which features your device has. Lessons that need a missing capability show a lock.
No. There is no sign-in. Prompts, answers, and saved runs stay on the device. The app does not talk to a developer server.
Lesson runs use the on-device model. Saved runs stay in the app. If you rate an answer, the app builds a feedback attachment on the device; you choose whether to share it. The Private Cloud Compute lesson only checks availability. It does not send a request.
That lesson writes a few sample notes into the app’s own Spotlight index so you can try the API. They are not uploaded anywhere.
The on-device model can refuse a prompt, hit a token limit, or return a weak answer. Try another example on the lesson, or open the Raw and Stats tabs to see what the framework returned. Email a screenshot if it looks like an app bug.
