The Loci method, or "Memory Palace," is a mnemonic memorization technique that involves associating the information you want to remember with locations in a familiar physical space.
This app displays rooms in a house. You can view each room at any time until you become familiar with them. When you select "Place 1 Picture," a famous painting will be randomly placed in each room. Once you've viewed them, you can go to the "Check Memory" option, where you can indicate which paintings were in each room. When you place them all, you'll be informed of how many you guessed correctly. This can also be done by placing two pictures using the "Place 2 Pictures" option. You can then check your memory of their location.
