When a student is stuck, they can request a hint with the click of a button. Research with iSnap used a simpler hint interface, based on the The above demo shows off iSnap's newest hint interface, but much of the earlier If the suggestion is followed, the button or input outline disappears, indicating the student has

Marketers can also use software subscription packages to build email lists, run promotions and build lead generation forms into the user interface. The company’s marketing analytics software then gathers shared customer data, usage statistics and demographics information. iSnap lets consumers snap branded photos at an event or venue and instantly share it via email and Facebook, Twitter and Foursquare.

Led by newly appointed Bob Whitson, CEO, with Alexander Lowe, founding CEO assuming the role of CTO, iSnap operates networked photo stations to connect offline and online experiences. The company intends to use the funds to scale its sales and marketing efforts and drive new product development. The round was led by a group of super angel investors from California and Europe. ISnap, a Sacramento, CA-based provider of networked photo stations, raised approximately $1m in Series A financing.
