PKR has launched an Android app called Spera, which it claims can help voters detect whether there are phantom voters in their polling districts.

PKR elections director Nurul Izzah Anwar said using the app, voters can report any suspicions they have about phantom voters, and the app would then cross-check the information provided using the latest electoral roll.

"The system will send a notification for phantom voters, repeat voters, and voters who have passed away by checking the data in Spera," Nurul Izzah told Malaysiakini when contacted.
