### 1/5 — Too many ads

*2025-10-25*

Why would you make such a horrible app that is free, gives only 5 generations and you force users to watch an ad to get more prompts. You’d be better off selling the app for $10 per download. Don’t get me wrong the app is beautiful BUT I hate ads and being FORCED to watch an ad
