📖 App Story ③
The third app began with a single user — someone who listened to the Bible on MP3 every day. The wish to turn that daily, compressed sound into the original recording opened an unexpected road.
Listen to the Bible as uncompressed original WAV, at whatever speed you like (1×–4×). Three voices — Korean, English, Chinese — and subtitles in seven languages, adding Japanese, Spanish, Vietnamese and Indonesian: it serves both meditation on the Word and language learning at once. Hear it with the ears, follow it with the eyes, write it with the hand — a triple drill. Rich in phonemes and high frequencies, Scripture also happens to be an ideal text for speed-listening training.
Unlike the first two apps, which started mostly with acquaintances at home, Speed Bible drew English-speaking users first, thanks to that very name. Installs ran around ten a day and then passed 200 within two weeks of launch. The familiar text of the Bible turned out to be good material for speed-listening that crosses the language barrier — which is why the subtitle expansion for foreigners learning Korean keeps going.
On the introduction of one businessman who reached his hearing and English-listening goals in a month, a church invited us to teach the speed-listening method to its youth and its fathers. It is no blockbuster in the numbers, but the path that spreads from person to person is the sturdier one — churches and mission groups can use it as a group for Bible read-through programs and for preparing English worship.
One word — “speed-listening” — in the app store brings up all three apps side by side.
