### 4/5 — The ads are way too long

*2026-08-10*

The app works just fine, but the ad you get at launch time takes way too long to be dismissible. It is bad enough that I recommend using another app unless you specifically need some feature in this one.

Update: Bumping the number of stars because the developer made a change to dramatically reduce the intrusiveness of the startup ad. Thanks!

**Developer response:** Hello, we sincerely apologize for the inconvenience.
Although ads are included to keep the app free, we are continuously working to make sure they don't disrupt your experience. Thank you for your valuable feedback, and we will keep striving to offer a better user experience while exploring ways to sustain the app seamlessly. Thank you.
