0 Stars if I could!!Though I’m in my 40s, I’m very tech savvy. I’m the one who fixes my family’s phones, etc, & I run a side business on my phone, including the contact info of 100s of clients.In an effort to clear some storage space on my phone, I researched various cleaning apps to find the best one for my needs. This included looking at a number of reviews from 3rd party sources. I decided to try this app. I encountered the following problems:1- No instructions were given about how to use the app & how it would affect your phone.2- I asked it to merge repeated contacts. Weeks later, I am still finding contacts it erased entirely!!!3- I asked it to delete duplicate photos, NOT similar photos. It decided 3 pictures I took at a friend’s wedding were too similar & deleted them all! Luckily I know how to retrieve them. Otherwise I wouldn’t have any of those pictures.4- It erased my personal contact information despite there being only one entry in my contacts. I had to completely reset Siri because she didn’t know my home address or who my relatives were. 5- The app erased my map settings. I use my GPS almost every day for work. Not because I don’t know where I am going, but to get from place to place efficiently. It’s hard for me to ask for directions to my home and other places I’ve marked when they no longer exist for the program to access.In summary, I wouldn’t trust this app to help you in any way. All it did was cause me trouble. Of course, I deleted it, but I wonder how long I’m going to be fixing the things it screwed up. Hopefully this review will act as a warning for the next consumer & save them time & worry.
