About this app

"I'm so busy with work and studying that I can't find a block of time to prepare for the TOEFL. Is there a way to study easily in my spare time...?"
"My listening and speaking scores are stagnating, and I don't know what to do..."

For busy business people and students facing these kinds of problems, **"To-Flue"** was developed to help you easily acquire the English skills I learned while studying abroad, after achieving a TOEFL score of over 100 while working.

【Three Reasons to Choose To-Flue】
① Visually See Your Pronunciation
It's hard to judge your own voice. To-Flue allows you to request pronunciation corrections, and you receive waveform analysis results, so you can visually see how your pronunciation is sounding.

② Efficient Use of Spare Time
Easily practice pronunciation while walking during your commute or during short breaks. We've carefully selected practice menus that can be completed in a short time, so they blend seamlessly into your busy daily life.

③ Affordable TOEFL Preparation
Pronunciation correction feedback starts from 100 yen per session. We offer TOEFL preparation, which is often expensive, at a very affordable price.

[Main Features]
Pronunciation Recording/Playing: Easily record and listen to your own pronunciation.

Visual Waveform: Compare your pronunciation with the example audio using waveforms to visually understand your intonation.

Review Request: Request correction of your pronunciation. You will receive feedback with a waveform display.

[Recommended for:]
Busy business professionals aiming for MBA studies or overseas assignments

Those who feel stuck in the speaking or listening sections

Those who want to try an affordable TOEFL preparation method before trying expensive ones
