With our two we started with a phone app and quickly learned the battery died at the worst times, so we switched to a little that model machine. Rechargeable battery plus a clip was the magic combo since we could hang it on a shelf or stroller and wander around the house without hunting outlets. I like the models that have just white and fan sounds and no obvious loop, I tried one that repeated every that model seconds and it drove me nuts once I noticed it. Keep it out of the crib, set it to low to medium, and let it run right through the nap. Easy.
