Did you know? Smiling produces endorphins which are the chemicals responsible for making us feel happy and reducing stress levels. Fake smiling has been shown to work as well as real smiling in producing endorphins as the brain cannot differentiate between the two. Studies have shown you can get many other benefits from smiling too such as boosted immune system, lower blood pressure, helps you stay positive to reduce anxiety and can even prolong your life. What is Smappy? Smappy is a first of its kind app that’s inspired by a practice called Laughing Yoga (Hasyayoga), which is an exercise involving prolonged voluntary laughter to help promote real and contagious laughter. Smappy aims to try and improve your mood by providing games and challenges controlled by your smile in an augmented reality setting using 3D characters. Features include: - Play games using facial recognition and AR that are designed to get you smiling. - Each smile performed when playing games is tracked so you can see how long you have smiled for. - Track your mood before and after playing a game to see how it changes your mood and also analyse your overall mood throughout the day/week/month or all time. - Compete against yourself to beat your personal records for each game. - Control the 3D character using facial tracking (Please note: Full facial tracking is currently only available on devices with a TrueDepth camera or A12 Bionic chip (with iOS 14)) - Try and complete daily challenges for a target smile time - Collect medals by completing challenges and achievements - No login required! - All data is stored on iCloud. So if you download the app on another device logged into the same iCloud it will sync overall data - Secure your data by requiring FaceID/TouchID when opening the app - Receive notification prompts to remind you to smile throughout the day and set how often you'd like to receive them - Dark Mode compatible + Stay tuned for more games and features Smappy Pro: Improve your experience by upgrading to Smappy Pro, which provides unlimited access to all features and removes adverts.

Verdict
The clearest difference is in-app purchases: Neckle at none against Smappy's 3. Smappy's advantage is update cadence (every 10 days vs every 2 months) and iOS requirement (13.0 vs 17.0). On price, ads and device support there is nothing between them.
