When you have kept many objects in different places and locations, it can be very challenging to remember when you need them in the future. This problem becomes worse when the objects are seldom used or moved about over the course of time or when your memory fails you due to ageing. This app aims to help you to recall easily. Note the location where the item is kept. Take pictures of the object and its current location so you don't have to second guess any more and be frustrated by hours of searching.
