### 1/5 — Too Many Ads

*2026-01-14*

Every time you open the app you must sit through endless, extremely annoying gaming ads before the actual app kicks in.  DELETED THE APP!

**Developer response:** Thanks for the feedback—sorry for the frustrating ad experience. I’m currently optimizing the ad behavior, including removing/reducing ads that appear when returning to the app from the background, so the app can start more smoothly. I’ll keep improving this to make the app usable without interruptions.
