### 1/5 — Bad user experience

*2026-01-16*

Jan 15, 2026

I was asked to rate your app with your “too early to ask that of any new downloaded, after one use that didn’t go well, pop up”. 

I gave one star. 

I read your app and thought it would be perfect. 

I ran my first audio compression, and nearly had a heart attack with your pop-up saying I had nine viruses attacking me and that it seemed eminent to be a disaster. 

I closed it. 

I reran it. 

I got a second heart thumping message that u had 125 viruses infecting my phone. 

The second one appeared to be a false looking Apple announcement. Though this compression was 3 out of 10, 10 being no change in compression, it resulted in 2.0% reduction in bytes. From about 5 MB original reduced now by 2. Percent. 

I am deleting this app. 

I won’t deal with more heart attack scare tactics. Yet you came across like a good company. You need to rethink my user experience. 
 
Regards,
XYZ
