The language menu, the phone in a stranger's hand, the screen you read instead of the face you should be looking at.
“Take one, my friend.” A street vendor in Greece is holding out something wrapped in paper, and you have no idea what it is, whether it is a gift or a sale, or what he just asked you.
You reach for your phone. And that is exactly where most pocket translators let you down. Here are the seven moments, and what the one-button disc does at each of them.
Every app makes you pick the language first. You scroll past Georgian and German and find Greek, and the vendor has moved on to the next customer while you are still holding a menu of flags. With ECDF you pick your two languages once, at home, in the free app. On the street it is one button.
To let someone answer, the app needs your unlocked phone in their hands. Your photos, your bank, your messages, handed to a taxi driver you met forty seconds ago. The disc hangs on your chest and speaks out loud. Nothing to hand over, nothing to get back.
A screen between two people is a wall with subtitles. You stare down at a line of text while the vendor watches your face for a reaction, shrugs, and you miss it. The disc says the sentence in his language while you keep your eyes on him. That is the whole difference between a transaction and a conversation.

Most tools translate your sentence and stop. His answer, in Greek, at full speed, is your problem. With the disc he presses, he talks, and you hear it in English. Both ways, every time, or it does not count.
An interpreter is billed by the hour. Screen translators run a few hundred dollars and still make the other person read. The disc is bought once, with no subscription and no credits that expire. The price is in the offer box below; you will not find it in a monthly plan.

Look-alike discs promise magic. Here is what ECDF actually does: you pair it once with the free ECDF app on your phone, by Bluetooth, choose your two languages, and the phone goes back in your pocket. It works wherever your phone works. The app also saves every conversation and corrects your grammar when you try the other language.
Call a friend who speaks Spanish. Press the button, say something, and let her answer. If it did not speak clearly both ways, send it back within 30 days for a full refund. Then take it on the whole trip and hold us to the same promise.

My dad has had a really hard time learning English, so going somewhere by himself is difficult. This little translator translates what he says and translates back whatever they answer. He can have his independence back.

‘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.

You press the button on your chest and say, “What is it?” The disc says it in Greek. He laughs, presses, and the disc tells you in English: it is loukoumades, honey doughnuts, and yes, they are for sale, two euros. You buy two. You never took your phone out.
In the box: the translator, a lanyard, a charging cable and a quick-start card.

Every one of the seven failures is the same failure: a tool that makes one of you read a screen. The fix is a disc that speaks, both ways, while you look at the person. Next time someone says “take one, my friend,” you will know what he means.
