Find answers to common questions about CheerLens
CheerLens is a professional iOS app designed to help you improve your smile confidence and interview skills. It uses AI-powered facial expression analysis to provide real-time feedback on your smile performance during practice sessions.
All features are available in both the free plan and unlimited access plan:
The only difference between plans is the daily time limit (3 minutes for free plan, unlimited for paid plan).
The free plan provides 3 minutes of total usage time per day (combined for both Smile Training and Smile Monitor features). All features are available, with only the daily time limit restriction. The daily usage limit resets every 24 hours based on calendar days. You can upgrade to unlimited access at any time through a one-time purchase.
Unlimited access is a one-time purchase of $29.99 that removes the daily time limit permanently. Once purchased, you'll have unlimited access to all features for as long as you use the app. The purchase is tied to your Apple ID and can be restored on other devices using the same Apple ID.
To restore your purchase, go to Settings in the app and tap "Restore Purchases" in the Purchase Status section. This will restore your unlimited access purchase if you've previously purchased it with the same Apple ID. The purchase is automatically restored when you reinstall the app on the same Apple ID.
No, CheerLens works completely offline. All features, including smile detection and analysis, work without an internet connection. The only time an internet connection is used is for in-app purchases (processed by Apple's App Store) and optional feedback submission.
Smile Detection Sensitivity is a setting that allows you to adjust how sensitive the app is to detecting smiles. You can fine-tune this setting in the app's settings to match your personal smile style. A higher sensitivity will detect more subtle smiles, while a lower sensitivity requires a more pronounced smile to be detected.
In Smile Training mode, you'll practice answering interview questions while the app analyzes your smile in real-time. The app provides various question sets to practice with, and you can see your smile performance as you answer. After each session, you'll get detailed analytics showing your smile ratio and performance trends.
Smile Monitor mode allows you to practice your smile expressions without answering questions. This mode focuses purely on facial expressions, making it perfect for dedicated smile practice sessions. The app continuously monitors your smile and provides real-time feedback.
No, CheerLens does not collect, store, or transmit any personal data. All processing is done locally on your device. Practice session history and results are stored only on your device and never leave your device. For more details, please see our Privacy Policy.
CheerLens requires iOS 14.0 or later and a device with a front-facing camera. The app is optimized for iPhone and iPad.
