Keybox Player AutoScript is an innovative repeat player app for learning a language.
Patent 10-2018-0005018 (Application N0.) With existing language repeater apps, you guess which part you want to replay, and clumsily move back-and-forth the proceeding bar. Keybox Player, on the other hand, splits the audio file and shows the corresponding script automatically. So you can pinpoint where you want to repeat. No guesswork, no error in section playing. Keybox Player let you repeat after audio sections and even scores how good your pronunciation is. Instead of passive listening mode, your language learning becomes more active and enhanced. Supports multiple languages (English, French, German, Chinese).

Keybox Player - AutoScript is free for repeater use. For script generation, points or ad views are required. ※ iTunes Subscription Warning - Payment is based on Appstore account - Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period - Account will be charged for renewal within 24 hours prior to the end of the current period, with the same amount as the first period. - Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase. - Cancel purchase is not permitted after use of service - Although your account is withdrawal status in app, you need cancel your subscription separately in Account Setting - Apple customer center waiting for you about payment problem Monthly Subscription(3,000SP, 5,000SP, 10,000SP) - If you subscribe subscription, you can get subscription points(SP) that can be used like points(P) - You can get subscription points as much as the subscription you choose every month, Subscription points not used in the previous month will be forfeited. - If you subscribe subscription, the subscription automatically renews every month. - You can cancel subscription anytime in appstore. - Refund can be unavailable about the first payment. - Above features can be changed. - Price may vary by location.

AB Loop Repeat for Language Learners [Universal Purchase] Buy once, enjoy across iPhone, iPad, and Mac. Cassette Tape is a media player built for one purpose: loop any section of audio or video with a single tap. Whether you are practicing English, Japanese, Chinese, or any other language, just set your A and B points and repeat that section as many times as you need. - AB Loop Repeat — Core Feature • A/B Point Setting Tap once to mark the start (A) of a section, tap again to mark the end (B). The player instantly loops that exact segment — a single sentence, a tricky phrase, or a short expression. Works with both audio and video files. • Repeat Count Control Set a specific number of loops or repeat infinitely. Once the count is reached, playback continues automatically from where you left off, keeping your session flowing. • Fine-Tune Adjustment Nudge the start and end points in 0.1-second increments using the fine-tune slider. Get the loop exactly right without having to re-record or edit your file. • Multiple Saved Segments Save as many loop sections as you need within a single file. Switch between them instantly to move between practice points during a study session. Keep yesterday's focus point and today's side by side. - Media Playback Plays MP3 and WAV audio files as well as MP4 video files. Adjust playback speed from 0.5x to 2.0x — slow down to catch every word, then gradually bring it up to full speed as your comprehension improves. Background playback keeps the audio running even when you lock your screen, with full controls available on the lock screen. Your last playback position is saved automatically so you can pick up exactly where you left off. - AI Subtitle Generation The built-in AI listens to your audio or video and automatically generates subtitles. Everything runs on your device without an internet connection, so your private study files stay private. Use the subtitles to follow along during listening, compare what you hear with what you read during dictation practice, or guide your listen-and-repeat sessions. - Bookmarks and Study Log Whenever you come across an important phrase, a difficult sentence, or a moment worth revisiting, tap the bookmark button to save that exact position instantly. You can attach a note to every bookmark — for example, "review this pronunciation," "key expression," or "needs more listen-and-repeat practice." All bookmarks are listed in one place and a single tap takes you straight back to that moment. As bookmarks accumulate across files, they naturally become a personalized study log that grows with you. - Additional Study Tools • Recent Files — quick access to your regular study materials • Playlist — group files and play them in sequence • Dark mode / Light mode - App Interface Languages Korean / English / Japanese / Simplified Chinese Loop it. Learn it. Level up.
