Have you noticed? Since recently, you need an IBI account to use the IBI app. With this account you can work from multiple devices. Your different address lists are now synced with your account, so you are always up to date! Your IBI settings are also synced across your devices, so you never have to worry about incorrect settings. Since you can work with multiple devices, you can input the addresses on your tablet or Windows computer and then take your phone to do the delivery work. With an IBI account, the delivery process is even simpler and faster.
