Misleading free trial and hidden subscription charges
Users are frustrated by the app's requirement to enter credit card details for a 'free' trial, with difficulty canceling subscriptions and unexpected billing.

reviews
- “Not free — Says try for free but requires credit card to test it. My experience is canceling if not liking is difficult at best. These types tend to run you in circles attempting to cancel”
- “This app is not free — I downloaded this “free” app, but on an iPhone IT IS NOT FREE. You get a week free after you put in your card info. Plus it does not do what the ads says it does.”
- “Overpriced — At $9.99 weekly I thought that I had cancelled immediately but continue to get billed, wouldn’t do it again. Wish I could give it zero stars.”
Failure to deliver advertised cleaning functionality
The app does not clean as promised—especially for non-photo/email data—and users report it only handles pictures, failing to address other storage areas.

- “Doesn’t do as advertised — Doesn’t clean ios files as advertised, pretty worthless when it only cleans pictures and contacts”
- “Nano means nothing — All that helps with is your pictures and that’s it does nothing about anything of any other storages doesn’t help with your emails doesn’t help with deep cleaning doesn’t nothing”
- “Not useful — I haven’t been able to take care of any of the areas that are full I don’t understand this new stuff. It was so much easier when I could just push button that said area that needed cleaning.”
Poor user interface and workflow issues
Users report losing progress, unresponsive buttons, inability to close screens, and confusing navigation that disrupts the cleanup process.

- “Garbage — Won’t let me close start screen. This just Keeps getting worse”
- “Cleaner no — I went thru the view of all the duplicates. Was in process of viewing and selecting pictures to delete got half way through and went off screen and lost it. Then went back. Now I would have to go through whole thing all over again.”
- “Unsubscribe does not work — I have gone to the area to unsubscribe. The continue button does not register. Be careful before you subscribe to this app.”
Ineffective duplicate detection and deletion
The app fails to properly identify or remove duplicate photos and contacts, forcing users to perform manual cleanup instead.
