Top 7 Apps for Cook Islands Travel You Need in 2026

Best Apps for Cook Islands Travel at a Glance

Travelling around the islands is easier when your phone works both online and offline. The right apps for Cook Islands travel can help you navigate, track buses, and check the weather. Here are some useful mobile apps to download before your trip.

1. Transportme Passenger

Rarotonga has just one main ring road, and this app lets you track the island's buses in real time. Buses run Clockwise and Anti-Clockwise, but GPS signals often drop along the south coast near Titikaveka. After logging in, search and select "Cook's Island Bus Passenger Transport LTD" to see live routes. When you see your bus coming along Ara Tapu, step out and wave. Buses can stop anywhere along the road, so don't wait for a physical shelter!

• Live GPS Tracking: See current bus locations on an island map.
• Stop Markers: Shows popular roadside pick-up spots starting at Cooks' Corner.
• Schedule Countdown: Shows estimated arrival times for upcoming stops.

2. Maps.me

When mobile service is slow on outer beaches, offline maps help you stay on track. Maps.me lets you download complete island maps, so you can find local ring roads, beach turnoffs, and dirt lanes across Rarotonga and Aitutaki. Keep in mind that auto-routing fails across Aitutaki's lagoon and outer islets (motu) where there are no roads. In these areas, you will need to drop manual pins instead.

• Vector Offlining: Saves complete island map packages directly to your phone.
• Point Searching: Locates gas stations, markets, and beach access without internet.
• Custom Bookmarks: Lets you pin favorite hidden spots along the O'otu Peninsula.

3. Windy.app

Lagoon tides and ocean winds can change quickly. Windy.app provides clear wind and wave updates to help you plan paddleboarding, snorkeling, or boat charters safely. Use it to double-check wind direction before heading out to Muri Beach, so you don't get swept up in strong offshore gusts.

• Wind Vectors: Displays easy-to-read wind direction and speed arrows.
• Swell Tracking: Shows wave heights, timing, and water surface temperatures.
• Multiple Models: Compares different weather forecasts side by side.

4. XE Currency

The Cook Islands uses the New Zealand Dollar (NZD) along with unique local coins (like the famous triangular $3 coin). Local coins trade 1:1 with NZD, but you can not spend or exchange them outside the islands. XE lets you check exchange rates offline, which is useful because vendors at Punanga Nui Market only accept cash.

• Offline Rates: Stores current exchange rates directly on your device.
• Multi-Currency View: Compares several world currencies on one screen.
• Instant Calculator: Converts totals in real time as you type in local prices.

5. VisitRaro

Finding opening hours for local restaurants and island tour guides can be difficult. VisitRaro works offline as a digital phone book with local business numbers (+682), restaurant menus, and event schedules. If you are using a data-only travel eSIM, save listed numbers to message vendors on WhatsApp or ask hotel staff to call them from a local landline.

• Vendor Directory: Organizes local restaurants, tours, and vehicle rentals by district.
• Offline Contacts: Saves phone numbers and addresses directly to your phone.
• Weekly Guides: Shows opening times for night markets and cultural shows.

6. AllTrails

Inland jungle trails wind past steep volcanic peaks where cell service can completely vanish. AllTrails provides downloadable topographic maps for cross-island hikes like Te Rua Manga (The Needle). Before entering the jungle, open the app and lock your GPS signal at the open trailhead. Thick forest canopies and steep valley walls can prevent GPS signals from connecting once you are under dense trees.

• Topographic Maps: Displays path contours and elevation changes for mountain passes.
• Offline GPS Navigation: Tracks your exact location using downloaded trail maps.
• Community Updates: Provides fresh alerts on trail mud, river crossings, and fallen trees.

7. SkyView

With almost zero light pollution, the Cook Islands offer incredible night skies for stargazing. SkyView uses your phone's sensors to map Southern Hemisphere constellations, planets, and satellites without needing data. Just point your camera at the sky!! One warning: move away from Black Rock's volcanic basalt rocks, as their magnetic minerals can affect your phone's compass and twist the star overlay.

• Offline Sky Maps: Shows star clusters and planets using your phone's internal compass.
• Augmented Overlays: Draws constellation outlines directly over live views of the night sky.
• Track Planets: Locates moon phases, planet positions, and satellite paths.
