### 1/5 — Keeps crashing

*2015-10-17*

I really had high hopes for this app because of the shear amount of duplicate contacts that I know I have.  However the app continuously crashes.  I have reinstalled the app twice and it still crashes.  Do yourself a favor a save your money.

### 1/5 — Import error

*2025-01-23*

This app would not import my csv or xlsx files

**Developer response:** Hello, please be aware that the application can only restore contacts from CSV or XLSX files created by itself. The application does not support CSV or XLSX files with a different format. Sincerely.

### 1/5 — Review on Contac Cleaner.

*2016-12-24*

I have this app on my iPhone and it works fine to clean the disk and memory.    On my iPad I have this app installed and I when I want to clean the disk and memory a flag comes up under it and says update info or updated info, and it will not let me clean either one.  This is the reason I bought it, so I can clean the disk and memory with no problems.   What can I do to correct this problem ?

### 4/5 — Contact Cleaner. Nice!

*2016-06-02*

Good......Put more interface emphasis on cleaning up junk files. Very Important!

### 3/5 — Works as stated.

*2017-07-30*

Wish Phan would update the app. 
It bothers me when the app seller/developer will duplicate the apps they have in the store instead of updating the current ones. The apps essentially do the same thing, and even look almost identical! 
Out of all the apps from this developer, only three have been updated this year, and one in the past year. 
To be fair, I've noticed other app creators do this too. ??
