You are also able to see the exact date and time when the scan was made, plus the depth and fish icons. You can also rename any record by pressing the Edit button on the right side of the screen and typing in your desired title or a comment. For Android devices, to delete your records you have to tap on the history item you want to delete and hold for a second, after which a delete icon will appear in top right of the screen. For iOS devices, you have to tap on the History item you want to delete and then swipe left, which will cause the Delete and Rename buttons to appear.
