You land at Suvarnabhumi Airport at 11:40 PM. Immigration took 45 minutes. Your phone has 12% battery. The taxi queue is chaotic, and someone is shouting “meter taxi!” at you while another guy waves a laminated price card. You open your phone. What app do you open first?
Most travel blogs give you a list of 20 apps. That’s useless. You need maybe five. This guide cuts the noise and tells you which travel apps in Thailand genuinely work in 2026, which ones are redundant, and where the hidden costs live.
Transport Apps: Grab vs. Bolt vs. InDriver — Which One Actually Gets You a Ride
Here’s the reality: Grab is the default in Thailand, but it’s no longer the cheapest. In 2026, Bolt consistently undercuts Grab by 15-30% on the same routes. InDriver lets you name your price, but drivers often reject lowball offers during rush hour.
| Feature | Grab | Bolt | InDriver |
|---|---|---|---|
| Base fare (Bangkok) | ฿45-55 | ฿35-45 | Negotiable |
| Availability | Excellent, 24/7 | Good, thinner at 3-5 AM | Spotty outside cities |
| Food delivery | Yes (GrabFood) | No | No |
| English UI | Yes | Yes | Yes |
| Card payment | Yes | Yes | Cash only mostly |
| Best for | Airport pickups, reliability | Budget rides in Bangkok, Chiang Mai | Short trips when you have time to haggle |
My verdict: Install Grab before you fly. It works at the airport, has the most drivers, and supports foreign credit cards. Install Bolt as your daily ride app once you’re settled. Keep InDriver as a backup for when surge pricing hits both.
One failure mode tourists hit constantly: Grab’s airport pickup zone. You can’t just pin anywhere at Suvarnabhumi. Follow the in-app instructions to the designated Grab pickup point on Level 1, Gate 4. If you pin the departure level, drivers cancel on you. That’s a ฿100 cancellation fee you won’t get back.
What About Taxis and Tuk-Tuks?
For metered taxis, the Bolt app now shows an estimated fare range even when you hail a street taxi. Use that number to negotiate. A taxi from Siam to Khao San Road should cost ฿80-120 on the meter. If a driver quotes ฿300 flat, walk away. Tuk-tuks have no app. They’re a novelty, not transportation. Expect to pay ฿100-200 for a 10-minute ride that costs ฿60 in a Bolt.
The One App You’ll Use More Than Any Other (And It’s Not a Travel App)
Line.
Thailand runs on Line. Restaurants take reservations through it. Tour operators send confirmations through it. Your hotel front desk will ask for your Line ID. If you only install one messaging app for Thailand, install Line.
Here’s why this matters practically: when you book a day trip through Klook or a local operator, they don’t email you. They send a Line message with your pickup time, driver photo, and van license plate. No Line = you’re checking email at 6 AM hoping the confirmation arrived.
Line also has a built-in translation feature that works better than Google Translate for Thai, because it handles informal Thai and local slang. And Line Pay is accepted at most convenience stores if you link a card.
Booking Tours and Transport: Klook vs. 12Go Asia — Know the Difference
These two apps solve completely different problems. Mixing them up costs you money.
Klook is for experiences: day tours, temple tickets, cooking classes, elephant sanctuaries, airport transfers. Prices are typically 10-20% below walk-up rates. The app shows real-time availability and instant confirmation. For a Chiang Mai cooking class, Klook lists dozens of options with reviews, and you can filter by vegetarian-friendly — which matters for this site’s readers.
12Go Asia is for point-to-point transport: trains, buses, ferries, minivans. Bangkok to Chiang Mai overnight train? 12Go. Koh Samui ferry plus bus combo? 12Go. The app aggregates operators and shows seat availability on a visual map. You pay a small booking fee (usually ฿30-80 per ticket), but you skip the chaos of buying at the station.
Failure mode: booking a train on Klook. Klook doesn’t do Thai State Railway tickets well. You’ll get a voucher that requires exchange at the station, and the seat you wanted may be gone. Use 12Go for trains. Use Klook for tours. Don’t cross the streams.
When to Skip Both Apps
For short-distance buses and songthaews (the red pickup trucks in Chiang Mai), no app helps. You flag them down, tell the driver your destination, and pay ฿30-50 in cash. Apps add a booking fee and a waiting time that makes no sense for a 15-minute ride.
Navigation and Food: Google Maps Is Fine, But You Need These Two Extras
Google Maps works in Thailand, but it has a blind spot: it routes you down sois (side streets) that are actually dead ends or private driveways. In Bangkok’s older neighborhoods, a 400-meter walking route can become a 20-minute detour because Maps doesn’t know a gate is locked.
The fix: cross-check with Maps.me or Organic Maps (the open-source successor to Maps.me). Both work offline and mark pedestrian paths that Google ignores. Download the Thailand map pack before you arrive.
For food, Foodpanda beats GrabFood for restaurant selection in Bangkok and Chiang Mai, especially for vegetarian and vegan spots. The app has a dedicated “vegetarian” filter that actually works, unlike GrabFood’s hit-or-miss tagging. Delivery fees run ฿10-40 depending on distance. If you’re in a hotel with no kitchen, Foodpanda becomes your default dinner solution.
One more: AirVisual. Chiang Mai’s burning season (February-April) pushes PM2.5 levels past 150 AQI regularly. AirVisual gives you real-time air quality data and a 7-day forecast. When the AQI is above 150, you should be indoors with an air purifier, not hiking Doi Suthep. This app genuinely changes your daily plans.
Money and Connectivity: What Nobody Tells You About Thai Banking Apps
You cannot use Thai banking apps as a tourist. PromptPay, the QR code payment system you’ll see everywhere, requires a Thai bank account. Tourists work around this with cash or international cards. Street food stalls, markets, and songthaews are cash-only. Carry ฿500-1,000 in small bills at all times.
For currency, use Wise or Revolut to convert before you arrive. Airport exchange counters at Suvarnabhumi give rates 5-8% worse than mid-market. A SuperRich exchange booth in the city (the orange ones) gives rates within 1% of mid-market. The app SuperRich Thailand shows live rates at all their branches so you can find the best one near you.
For SIM cards, skip the airport kiosks. An AIS or TrueMove eSIM from Airalo or Nomad costs $8-12 for 15GB of 5G data. The same plan at the airport costs ฿699 (about $20). Install the eSIM before you fly, activate on landing, and you have data before you leave the gate.
The App You Should Delete Before You Arrive
Delete your home country’s ride-share app. Uber doesn’t operate in Thailand. Lyft doesn’t either. Keeping them installed just adds clutter and confusion when you’re jet-lagged and trying to get out of the airport at midnight.
And honestly, delete most travel planning apps. You don’t need TripIt, TripCase, and three itinerary managers. One Google Doc or a notes app with your booking references does the same job without burning battery syncing in the background.
The Five-App Setup That Actually Works
Here’s the compressed verdict. Install these five before you fly:
- Grab — airport transport, reliability, card payment
- Bolt — daily rides, cheaper than Grab
- Line — communication with hotels, tour operators, everyone
- 12Go Asia — trains, buses, ferries between cities
- Klook — day tours, activities, airport transfers
Add Foodpanda if you’re staying more than a week. Add AirVisual if you’re visiting between February and April. Add an eSIM app (Airalo or Nomad) before you board.
Everything else is noise. Every extra app is a background process draining your battery while you’re trying to navigate a city where street signs are in Thai and the heat is 35°C.
The single most important takeaway: install Grab, Bolt, and Line before you land, because the airport is the worst place to be fumbling with app downloads on airport Wi-Fi.
