A private AI field guide that works with no signal.
Ask a question, get a cited answer — from an AI model that runs entirely on your iPhone. No cloud, no account, no data collected.
Offline
Fieldwise works without a network connection. Knowledge packs and the on-device AI model live on your phone — you only need the internet once, to install them.
Source-grounded
Every answer cites the entries it relied on. Tap a source chip to read the original. If the pack doesn't cover your question, the app says so instead of guessing.
Private
No analytics, no advertising IDs, no third-party SDKs. The App Store privacy label says "Data Not Collected." We mean it.
Featured packs
See all 12 →Long-Term Food Storage
Practical reference on storing dry staples, preserving food, and managing pantry inventory for years rather than months.
Wilderness First Aid
Field reference for first-aid scenarios in remote settings. General reference only — not a substitute for professional medical advice.
Stars & Constellations
Field reference for naked-eye astronomy — finding north, identifying bright stars and constellations, recognizing planets, and tracking the Moon and meteor showers.
Knots Reference
Field reference for common knots, hitches, and lashings — what they're for, how they're tied, and where they fail.
