### 1/5 — Fully Nude Porn Ads

*2026-07-27*

In addition to the review title, I ’ll add that the Apple profile I use is strictly for music production and nothing one could consider to be non-work safe, so the ads are not a bleed-over from my browsing habits. As I really hoped to use your app, I even created a new profile and met the same results. As a result, I'll unfortunately not be using your app until this is remedied, nor will I pay for the full version just to remove the type of ads that shouldn't be shown in this particular circumstance to begin with. Best of luck with your endeavors and thank you for your consideration here.
