iSpi is the app that identifies major landmarks in the top tourist destination cities in the world. Find a viewpoint with an unobstructed view of the city you are in. It works best in open areas so avoid using in enclosed spaces. Open iSpi and select the city. The app will then access the camera on the device. At the centre of the screen is a viewfinder rectangle. Pan the device horizontally and when it recognises landmarks in the viewfinder area an information label will appear identifying the landmark. iSpi currently works in the following cities:Amsterdam, NetherlandsBangkok, ThailandBarcelona, SpainBeijing, ChinaBerlin, GermanyBuenos Aires, ArgentinaCape Town, South AfricaChiang Mai, ThailandChicago, United States of AmericaDubai, United Arab EmiratesFlorence, ItalyHong Kong, ChinaIstanbul, TurkeyKuala Lumpur, MalaysiaLondon, United KingdomLos Angeles, United States of AmericaMarrakech, MoroccoMilan, ItalyNew York, United States of AmericaParis, FrancePrague, Czech RepublicQueenstown, New ZealandRio de Janeiro, BrazilRiyadh, Saudi ArabiaRome, ItalySaint Petersburg, RussiaSan Francisco, United States of AmericaSeoul, South KoreaShanghai, ChinaSiem Reap, CambodiaSingapore, Republic of SingaporeSydney, AustraliaTaipei, TaiwanTokyo, JapanVenice, ItalyVienna, Austria
