Yes, a few iPhone apps can answer travel questions with no internet connection, and they do it in one of two ways. Either the AI model runs on your phone, so you can ask new questions in airplane mode, or an AI writes guide content while you are online and you save it for later, so only what you saved works offline. Roam Offline, which we make, is the first kind: an on-device AI local guide plus a phrasebook and country basics. If what you really need offline is a map or a deep destination guide, two free tools do that better than any AI app: Google Maps offline areas and the Wikivoyage travel guide in Kiwix. Most travelers are best served by one of each.
Who wrote this: the maker of Roam Offline (Vilde Vevatne, an independent developer). Roam Offline is our app, so read our view of it with that in mind. Nobody paid to be included here, and there are no affiliate links. Facts about other apps come from their own App Store listings, websites and help pages, checked November 8, 2026; prices are US App Store prices and can change.
Two kinds of "offline AI"
- An on-device model. The AI itself is stored on your phone. You can ask anything at any time, with no signal. The trade-off: models small enough to run on a phone give shorter answers than big cloud chatbots, can be wrong, and know nothing live (today's strike, this week's opening hours, train times).
- AI content you download. Tours, landmark write-ups or itineraries are generated while you are online and saved to your phone. They read reliably offline, but you can't ask a new question once you're out of signal.
App listings often just say "works offline", so check which kind you're getting: the quickest test is to switch on airplane mode at home and ask the app something you haven't asked before.
The options, side by side
| App | What works with no signal | Price (US) |
|---|---|---|
| Roam Offline (ours) | On-device AI guide for practical questions (tipping, transport, customs), a phrasebook, and emergency numbers, plugs, currency and tipping for 48 countries. | Free with 3 AI questions; Roam Pro $2.99/month or $14.99/year |
| Aitour: Travel AI Guide | AI-made voice tours and landmark descriptions. Its listing says you can "save your favorite routes and landmark details so you can explore confidently without roaming data." It doesn't say whether new tours or the landmark scanner work offline. | Free download; in-app monthly plans listed at $4.99 and $29.99 |
| Kiwix + Wikivoyage (not AI) | Download a whole reference library once and read it offline. The Kiwix library includes Wikivoyage, the free wiki travel guide. | Free; the listing says Kiwix is a non-profit with no ads |
| Google Maps offline areas (not AI) | A downloaded map area you can search and drive with. Google says that offline, transit, cycling and walking directions aren't available, and some regions can't be downloaded. | Free |
On a phone, swipe the table sideways to see every column.
What Roam Offline's guide can and can't do
You pick a country and ask in plain words: "How much do I tip in a restaurant here?", "Is the tap water safe?", "How do I get from the airport to the centre?" The answer is written on your phone, without your question leaving the device.
- Which model answers. On iPhones with Apple Intelligence (iPhone 15 Pro and newer models, per Apple's device list), Roam uses Apple's on-device model. On other iPhones it offers a one-time download of its own on-device model (about 590 MB; do it on Wi-Fi before you travel). The app needs iOS 17 or later.
- What it's good for. General, slow-changing know-how: customs, tipping norms, how transport usually works, what to say in a pharmacy.
- What it can't know. Anything live. Since version 1.0.6 the guide says when a question needs a live source (schedules, events) instead of guessing, per the App Store release notes. Treat answers as general guidance, not professional, medical or legal advice, and confirm anything important locally.
- Price. 3 questions are free; unlimited questions are part of Roam Pro ($2.99/month or $14.99/year, no free trial).
Set it up before you fly
- Install your AI guide app at home and finish any model download on Wi-Fi.
- Turn on airplane mode and ask it one new question, to prove it really answers offline.
- Download offline map areas for every city on your route.
- Download Wikivoyage (or just the region you need) in Kiwix if you want a full written guide.
- Download your translator's languages too; see Roam Offline vs Google Translate vs iTranslate.
