The free phone app, a screen translator, a one-button disc: five pass-or-fail questions, then a taxi ride that settled it.
In the video a young man says "Watch this, I speak English: where is the beach?" into a disc on his chest, and the disc asks it in Spanish, out loud. The answer comes back to him in English.
The question we get most since that video is fair: how is that different from the app already on my phone? So we took the three options people mention most on the same errands for a month.
No scores, because we would be grading our own homework. Six plain rows instead, five questions and one trade-off, each one you can check with your own eyes.
Look at the rows again. The app and the screen gadget lose on the same line: somebody has to look down.
The phone app was built for one person reading one screen. A conversation is two people, two directions, and the second person is a stranger who never agreed to read your phone.
The screen translator fixes the phone problem and keeps the reading problem. Two people hunched over a second screen is still not a conversation; it is a shared homework sheet.
Our tie-breaker. You are in a cab, the driver's eyes are on the road, and you need the hotel by the old harbor, not the one by the airport.
In the back of that cab you really have three choices.
Only the third choice lets the driver keep driving. The app failed the test outright; the screen gadget got the hotel name across and then had to be passed over the seat for the answer.
Write the test as a list and it reads like this. A real fix has to:
The ECDF translator is a round disc, matte graphite, hockey-puck size, with one microphone button in the center and a small blue light. It hangs on a lanyard on your chest or sits in your palm.
Set it up once in the free ECDF app on your phone, over Bluetooth, choose your two languages, and the phone goes back in your bag. From then on it is one button, and it works wherever your phone works.
Press and ask for the beach; it asks in Spanish. The man answers in Spanish, presses, and you hear his answer in English, with nothing typed, nothing read, and 165 languages printed on the box.
This was the one row we could not put in a table, so here it is in words. The sentence leaves the disc, the answer goes back into the disc, and the two of you keep looking at each other.
The taxi driver noticed. The woman at the pharmacy counter noticed, and after a week we stopped noticing, because it had started to feel like talking.

Thirteen years selling cars, and all the Spanish-speaking customers I’ve missed because I didn’t have this. Real-time translation, and all I need is Spanish. I’m going to be unstoppable.

‘Hello my friend, how are you? Can you help me, please?’ It says it in Spanish, then my Spanish comes back in English. Spanish to English and English to Spanish.

‘My name is Melissa.’ It said it back in Spanish. Then I spoke in Spanish and it came back in English, out loud, with the translator just hanging on my chest.

Look for: something that talks in both directions, lives on your body rather than in your hand, runs on one button, and is bought once.
Walk past: anything you must hand to a stranger, anything that makes both of you look down, and anything that bills you monthly for a trip you take twice a year.
Yes, the winner is ours. The taxi test is not; run it with the app on your next ride and watch where the driver's eyes go.
In the box: the translator, a lanyard, a charging cable and a quick-start card.
See today's offerTry it for your whole trip. Not amazed? Send it back within 30 days for a full refund.
We can publish a table all day. The test that matters is yours. Take the disc on the whole trip. Wear it into the first cab, press it at the pharmacy, hand it across a market stall. Ask the driver for the hotel by the old harbor and see whether his eyes leave the road. If, after the whole trip, you are not amazed, send it back within 30 days and we refund every cent. We would rather you test it in a cab than take our word for it.
It pairs with your phone, so keep the phone in your pocket or bag. Set-up is once, in the free ECDF app over Bluetooth; after that you press the disc and the phone stays put. Nobody in the cab ever sees it.
Through the free app it uses your phone's connection, which means it works wherever your phone works. Check that your phone works at your destination before you go; if it does, the disc does too. There is nothing extra to buy from us.
Yes. He presses the same button, talks in his language, and the disc says his answer to you in English. He does not need the app, your phone, or a lesson: one press, then talk.
Speak at a normal pace, one sentence at a time, and ask them to do the same. If something comes back odd, press and say it a shorter way. Each exchange is saved in the app so you can read it back later.
No. You buy the disc once, the app is free, and there are no credits that expire between trips. Nothing renews, nothing bills you monthly.
Charge it with the cable in the box and it is good for days of normal use. Charge it the night before a travel day, the same time you charge your phone.
Contact ECDF support within 30 days of receiving it, follow the return steps, and you get a full refund once it is back with us. Use it on the whole trip first; the guarantee exists for exactly that.
165, printed on the box. You pick the two you need in the app before you go, and you can change the pair for the next stop on the trip.
The winner is not the fanciest gadget on the table. It is the only one that let a taxi driver keep driving while he answered us. Your phone stays where your wallet is, your eyes stay on the person, and the answer comes back to you in English. Take it on the next trip and run the test in the first cab.
