Find anything without much battery penalty
Here is the long and short of it. It is annoying to have to leave the application running on my iPhone to keep track of everything. However, it works brilliantly. I have also been testing the battery penalty on my iPhone 6s Plus. From my testing for 5 days, the best estimate that I can provide is it costs maybe 3-4%. This is keeping it running without going in and looking for things constantly. If you do lose something tiled, I dont care what the battery consumption is as long as I find it!
