The aim of this application is to enable visitors to the Istana to identify and visit key places of interest and plants within the Istana Garden and to learn something interesting. At each of these locations, visitors can scan displayed QR codes to obtain more information about the places or plants of interest. This application would be useful for all visitors to the Istana Garden during the Istana Open House, especially those who would like an interactive self-guided tour around the Istana grounds.

Those who visit all the sites in the Places of Interest Trail will get 12 green butterflies in their app while those who check out all the plants in the Plants Trail will get 10 purple leaves on their app. Those who completed one or both trails will receive an Istana souvenir (while stocks last) from the redemption counter.

*DISCLAIMER: This is not a typical QR scanner application; it is only meant to scan the QR codes stationed at the Istana, Singapore.
