Read full descriptionHide full description
Practice your smile before an interview, presentation, photo, or important conversation. Smile Trainer turns your front camera into a private mirror and gives you one focused minute to practice a natural expression. There is no score to chase and no automated judgment. Look ahead, relax, and smile at your own pace. THE ROUTINE 1. Open the mirror from the home screen. 2. Practice for one minute while the timer runs. 3. Do up to three sessions a day. Your allowance returns at midnight, local time. 4. Come back the next day to extend your streak. A history screen lists the date and time of every session you completed. WHAT THE CAMERA DOES - The front camera is shown on screen as a live mirror and nowhere else - Camera images are not analyzed, recorded, uploaded, or stored - Your daily count, streak, and history (dates and times only) stay on your device - No login is needed to use any of it ADS Smile Trainer is free. The only ad is one small banner along the bottom edge of the home screen. The mirror and the result screen never carry one, so nothing competes with your face while you practice. In regions where the law requires it, such as the EEA and the UK, a consent form lets you choose before any ad loads. You can reopen it later from Settings under Ad privacy options. On iPhone and iPad, the system tracking prompt appears only if that choice allows it, and the app works fully whichever way you answer. LANGUAGES English, Korean, Japanese, Simplified Chinese, and Traditional Chinese, matching your device's language. IPHONE AND IPAD On iPad, the app runs full screen in portrait with a larger mirror and text, and the routine is the same as on iPhone. NOT A MEDICAL TOOL Smile Trainer is a practice mirror for everyday confidence. It does not measure, diagnose, or treat anything. Questions or feedback: contact+smile-trainer@peppertree.so
