If a cloudy day makes you tired, the app would recommend a smell of peppermint or citrus for added pep in your step.
The What's Happening button asks for a user's current weather: bright, cloudy, drizzly, smog or humid. The How Do You Feel button gets personal: Are you cold, tired, energetic, headache or focused? Once answered, customized advice is offered. The app is available in the App Store and Google Play.
