I have constant ringing in my ears (tinnitus) that nearly drives me crazy when everything is perfectly quiet, making it very hard to go to sleep. But, problem solved by letting this app read me a book (if there is some sound for me to hear, I don’t notice the tinnitus). Before I lay down, I set the sleep timer for 15 minutes, then I relax while I listen to the story and it turns itself off after I am asleep. The best part is, you can use the bookmark feature to save your place periodically, then you can easily find your place by going to your bookmark and using the fast forward and 15 second advance (or 15 second back up) buttons. I use OverDrive EVERY night. Caution: save thrillers and page turners to listen to on long car rides! For bedtime, I listen to funny, stress free stories like Janet Evanovich books- they are funny and entertaining and don’t keep me awake. Last tip, for best results to induce sleep, I listen to the my favorite books over and over. That way, I don’t have to worry about ‘missing something’. You can have up to five books at a time, so I also listen to this app while I am cleaning house, gardening (great time to listen to “how-to” books) or driving (it plays through my cars speakers). Best of all, you can temporarily download the books to your phone so you can listen to it even if you don’t have wi-fi available. Love OverDrive!!!
