Visualize Fitbit steps with Notch▲34
Hi folks, wanted to get feedback on a project before making it 'public'. It's called Notch and the idea is to create a more fun UX for personal health tracking (using data from Fitbit, Fuelband, Withings, etc). The demo project is a first experiment with this. The 'private' signup page is at http://notch.me/start.html. Users go in, add their Fitbit, and it creates a personalized infographic based on their Fitbit steps, like this: http://notch.me/p/7Isumkw5k2P1WhyeUVwFmj Feedback is appreciated! Feel free to email me at [email protected]. Thanks! Eli
