Ferryhopper, Beat, maps — 12 must-haves for Greece.
Essential apps for Greece travel – TL;DR
The core of any Greece trip is the ferry. Of Greece's 6,000+ islands, roughly 200 are inhabited, and the ferry network connecting them is the lifeline of travel here. From Athens's Piraeus port, a ferry gets you to Aegean highlights like Santorini (8 hours) or Mykonos (5.5 hours).

1. Ferries — Ferryhopper is absolutely essential
Ferryhopper
A platform dedicated to Greek and Mediterranean ferry bookings, founded in Athens in 2017. The only integrated platform for comparing and booking across 59 ferry companies and 250+ routes serving the Aegean, Ionian, Crete, and the Dodecanese islands, all in one app. An essential app for Greek island-hopping trips.
- Full route coverage: every route departing Athens (Piraeus, Rafina, Heraklion) plus inter-island routes
- Connection search: search a multi-island loop like Athens→Santorini→Mykonos→Naxos→Paros→Athens all in one go
- Seat class selection: choose by class — Economy Deck, Economy Cabin, Business Cabin, VIP, and more
- Vehicle transport: also book an option to load a rental car or motorcycle onto the ferry
- Mobile ticket: board with a QR code, check in from your phone with no printing needed
- Real-time sailing status: real-time alerts for ferry cancellations or delays due to weather or strikes
- Cancellation policy: cancellable tickets can be refunded 24–48 hours before departure
⚠️ Note: during Greece's summer peak season (July–August), Athens↔Santorini/Mykonos ferries sell out weeks in advance. Book as soon as your dates are set. During summer's strong Aegean northerly winds (the Meltemi), ferry departures can be canceled suddenly, so on days with an important flight connection, consider a domestic flight instead of a ferry.

Omio
Besides ferries, an integrated transport booking platform that also lets you compare trains from Athens to Thessaloniki, domestic Athens-Santorini flights, and more.
- Ferry vs. flight comparison: compare Athens→Santorini ferry (8 hours, €35–80) against a flight (45 minutes, €50–150) on price and time
- When the weather turns bad: quickly find a domestic flight alternative on days when Aegean waves run high instead of taking the ferry

2. Taxi
Uber
Uber operates in Athens, connecting you with officially licensed VTC drivers. Uber is convenient for getting from Athens Airport (Eleftherios Venizelos) into the city.
- Athens airport pickup: airport→downtown Athens (about 35km) costs roughly €35–50 on Uber
- Acropolis→Piraeus port: Uber is more convenient than the metro when you have a lot of luggage before boarding a ferry
- Late-night travel: Athens's late-night public transit is limited, making Uber essential for an early-morning ferry departure
📱 Download: App Store | Google Play
Bolt
A ride-hailing app competing with Uber in Athens and Thessaloniki, sometimes cheaper than Uber during peak times. Compare both apps at once and choose whichever is cheaper.
- Downtown Athens: both Uber and Bolt are active, making price comparison during surge periods effective
- Taxis on the islands: Uber and Bolt don't operate on islands like Santorini or Mykonos → use a local taxi or rent an ATV instead
📱 Download: App Store | Google Play
3. Maps & navigation
Google Maps
Provides maps across Greece, including Athens, Santorini, Mykonos, and Crete. Covers Athens's metro/tram/bus routes, island roads and hiking trails, and reviews for local restaurants and attractions.
- Offline saving essential: Aegean island connectivity infrastructure is unreliable → saving maps for your destination island offline is essential
- Santorini cliff paths: guidance for the Fira→Oia walking route along the caldera cliffside
- The Mykonos maze: GPS guidance through Mykonos Town's maze-like alleys
- Crete rental car: guidance for cross-Crete roads and Samaria Gorge parking locations
📱 Download: App Store | Google Play
4. Athens public transit
OASA Telematics
The official app of the Athens Urban Transport Organization (OASA), providing real-time information for the Athens Metro, buses, trams, and electric rail. Useful for checking your route when taking the metro (Metro Line 3, blue) from Athens Airport into the city.
- Airport metro: a direct Metro Line 3 connection between Athens Airport↔Syntagma Square, 40 minutes, €10
- Day pass: an unlimited-ride Athens transit day pass (€4.5) — economical since most attractions cluster near metro stations
- City trams: information on tram routes toward the Athens coast and Palaio Faliro
- Real-time arrivals: real-time estimated bus arrival times at stops
📱 Download: App Store | Google Play
Citymapper
An app usable alongside OASA for calculating Athens public transit routes. Especially intuitive for calculating optimal routes combining metro, bus, tram, and walking.
📱 Download: App Store | Google Play
5. Accommodation
Booking.com
Book hotels, luxury suites, and apartments across Greece. Santorini caldera-view suites can run $300–1,500/night during peak season (June–September) and require booking months ahead.
- Santorini caldera views: caldera-view accommodations in Fira, Imerovigli, and Oia — book 3–6 months ahead during peak season
- Near Mykonos beach clubs: accommodations near Paradise Beach and Super Paradise Beach, in a party atmosphere
- Crete resorts: beach resorts in Heraklion, Rethymno, and Chania
📱 Download: App Store | Google Play
Airbnb
Renting an entire traditional whitewashed Greek island house (Cycladic architecture) is a popular experience. Santorini's cave houses, traditional houses near Mykonos's windmills, and Naxos farm stays are all popular picks.
- Santorini cave house: a house carved into a volcanic cliff — cool and unique thanks to natural insulation
- Naxos/Paros: experience authentic Greek island life affordably on lesser-known islands
- Long-stay discounts: weekly discounts on bookings of 7+ nights — good for travelers staying a while on one island
📱 Download: App Store | Google Play
6. Translation
Google Translate
Greek uses the Greek alphabet (α, β, γ, δ...), completely different from the Latin alphabet, so even reading a sign or menu can be difficult. Use camera translation to instantly translate Greek text.
- Greek offline pack: essential for preparing for unreliable connectivity on Aegean islands
- Camera translation: instantly translate Greek menus, signs, and museum descriptions
- Learning the alphabet: knowing "Ευχαριστώ" (efharisto, thank you) and "Καλημέρα" (kalimera, good morning/hello) is very well received by locals
📱 Download: App Store | Google Play
7. Dining & reservations
TheFork
Offers restaurant reservations and discounts in Athens and Thessaloniki. TheFork is partly supported on mainland Greece, but on islands like Santorini and Mykonos, contacting the restaurant directly or visiting in person is often necessary.
- Athens fine dining: book Acropolis-view restaurants and restaurants near Monastiraki Square
- Discounts: filter for restaurants with the YUMS discount applied
- Meze restaurants: book restaurants specializing in traditional Greek small plates (meze)
📱 Download: App Store | Google Play
8. Payments
Wise
A fintech app that minimizes exchange-rate loss when paying in euros (EUR). Greece has used the euro since joining the eurozone in 2002. Card payment is common in Athens and major cities, but small restaurants, markets, and fishing village cafés on smaller islands sometimes only accept cash.
- Euro account: top up your Wise euro balance and pay by card
- Prepare cash: always carry cash (€50–100) when visiting smaller Aegean islands
- ATM access: Santorini and Mykonos have ATMs, but smaller islands may not — withdraw cash before departing Piraeus
📱 Download: App Store | Google Play
Revolut
A multi-currency management app including the euro, also useful in a continuous itinerary if you're moving on from Greece to Turkey, Italy, or Croatia.
📱 Download: App Store | Google Play
9. Tours & activities
GetYourGuide
An app for booking tours and admission tickets across Greece. Book an Athens Acropolis guided tour, a Santorini sunset cruise, a Mykonos beach tour, a Meteora monastery day trip, a Delphi archaeological site tour, or a Crete Samaria Gorge trek.
- Book the Acropolis in advance: on-site ticket lines are long — advance booking is recommended, especially during summer peak season
- Santorini sunset cruise: the sunset viewed from Oia is world-famous → popular cruises sell out weeks ahead
- Meteora day trip: visit the Meteora monasteries from Thessaloniki or Kalambaka — advance booking recommended
📱 Download: App Store | Google Play
Klook
An app for booking Greece tours in your own language. Conveniently book Acropolis and Athens city tours, Santorini island tours, and more through a fully localized interface.
📱 Download: App Store | Google Play
10. Weather
AccuWeather
Greece has a Mediterranean climate — clear and dry in summer (June–September) — but the strong Aegean northerly wind (the Meltemi) can lead to ferry cancellations. Use AccuWeather to check Aegean wind and wave conditions the day before and the day of your ferry departure.
- Meltemi winds: strong Aegean winds in July–August — small ferries are canceled once waves exceed 3m
- UV index: Greek summer UV is very strong — always check the UV index before beach activities
- Heat waves: Athens summer heat waves reach 38–42°C — visit the Acropolis between 8–10am if possible
