My two issues are that there are a lot of ads shown and that the artists of the art are not shown. An ad is shown basically after every click and the artists that made the art shown are not provided, so, I’m unable to find more art similar to what I see. Otherwise, the app is good, works well, and, if my issues I mentioned were fixed, would be perfect. ### 4/5 — Pretty good overall *2026-04-27, version 1.0* It makes you watch ads every page but other than that it lets you download it to photos to make wallpapers so it’s good ### 4/5 — Hi *2024-05-24, version 1.0* Its good but to many adds not enough pictures and not a lot of characters in the pictures ### 4/5 — Not bad, but two problems *2023-03-19, version 1.0* 1) Before leaving this review, it popped up with “Rate this app” far too often, which is a little ridiculous. 2) ADS! There’s an ad almost every time you change a page, and while it is an option to remove them, but this is just too much. Otherwise, this is a very good and cool app! ### 5/5 — The best game *2023-03-09, version 1.0* The best wallpapers are on here ### 4/5 — Well they got good wallpapers but *2023-01-08, version 1.0* The adds man, I just can’t handle the adds, there are to many, I know you guys have to make money to but maybe not so much, please ### 5/5 — Ty *2023-01-02, version 1.0* Thank you this game is so good I had boring wallpapers I got this and I have two new wallpapers that have my favorites aus like ink error after and swap 5⭐️ I recommend this game ### 5/5 — snas *2022-12-24, version 1.0* sans underman ### 5/5 — Todo *2022-12-23, version 1.0* Nice ### 5/5 — I LOVE my new wallpaper *2022-09-26, version 1.0* This app is awsome for any big undertale fan it is totally free awsome backgrounds i have one of the many Chara. But I would love for them to add some Temmie wallpapers ### 4/5 — Great art but… *2022-08-18, version 1.0* Really great art and well done to all the creators but there are so many ads. I can understand a free app monetising itself through ads but I can’t move around without an ad. I spent more time clicking the x button that looking at art. Maybe just tone it back a little ## Most critical reviews (10 lowest-rated) ### 1/5 — I hate kids *2024-12-19* Creeper?
