On-device AI for Apple platforms.
No per-token bills. No data leaving the device. Shipped in production, not slideware.
AltoCode is a senior-led practice that moves AI features on-device across iPhone, iPad, and Mac — and ships its own apps on the same Apple stack.
On-Device AI
Move an AI feature on-device, or build a new one that runs entirely on the phone.
- No per-token bills — cost per query stays $0
- Responses stay fast on any connection — no network round-trip, even offline
- Data never leaves the device
- Shipped in production, not slideware
Apps we've shipped
We ship our own apps — each one proves a side of the practice.
WhattaRAG · our on-device AI proof
On-device RAG on the phone: embeddings, vector search, and LLM generation entirely on-device. 100% native Swift, ~4 MB, no servers, no accounts.
MindStorm · proof we ship complete native apps
A polished iPhone app designed, built, and shipped to the App Store — evidence of the craft behind the general practice.
AltoCode
A senior-led Apple-platforms engineering practice, driven by Fernando Putallaz. Senior work directly — no agency margin, no juniors behind a senior's name.
On-device AI is the specialty — but not the only door. Need a senior iOS engineer who ships production-quality native Swift (architecture, features, stability)? That work is welcome too.
