### 5/5 — Amazing wallpapers

*2026-08-06, version 1.0*

I like the under tale’s wallpapers

### 4/5 — Pretty good, only some minor critiques

*2026-06-07, version 1.0*

The app is easy to understand and use, (seemingly) doesn’t give you a virus, and the main functions work as expected. 

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

### 3/5 — Good wallpaper but here’s the thing

*2026-01-19, version 1.0*

I’m a very big Undertale fan and they are very good wallpapers, but there are a lot of ads and I could barely even look at any of the wallpapers. Oh, and I have a suggestion in the Undertale heart. Why don’t you put despite everything it’s still you with the determination heart of course ❤️

### 5/5 — Cool

*2025-07-05, version 1.0*

It is really good

### 3/5 — Good but ads

*2025-06-14, version 1.0*

Too many ads. I can’t click off or on something without an ad popping up. Although it is really good at getting my fav wallpaper

### 5/5 — Cute

*2025-03-29, version 1.0*

Very cute some of them are a bit gainsaid promd

### 5/5 — Sans

*2025-03-15, version 1.0*

Idk but I love this

### 1/5 — I hate kids

*2024-12-19*

Creeper?
Aww, man
So we back in the mine
Got our pickaxe swinging from side to side
Side-side to side
This task, a grueling one
Hope to find some diamonds tonight, night, night
Diamonds tonight
Heads up
You hear a sound, turn around and look up
Total shock fills your body
Oh, no, it's you again
I can never forget those eyes, eyes, eyes
Eyes-eye-eyes
'Cause, baby, tonight
The creeper's tryna steal all our stuff again
'Cause, baby, tonight
You grab your pick, shovel, and bolt again (bolt again)
And run, run until it's done, done
Until the sun comes up in the morning
'Cause, baby, tonight
The creeper's tryna steal all our stuff again (stuff again)
Just when you think you're safe
Overhear some hissing from right behind
Right-right behind
That's a nice life you have
Shame, it's gotta end at this time, time, time
Time-time-time-time
Blows up
Then your health bar drops and you could use a one-up
Get inside, don't be tardy
So, now you're stuck in there
Half a heart is left, but don't die, die, die
Die-die-die
'Cause, baby, tonight
The creeper's tryna steal all our stuff again
'Cause, baby, tonight
You grab your pick, shovel, and bolt again (bolt again)
And run, run until it's done, done
Until the sun comes up in the morning
'Cause, baby, tonight
The creeper's tryna steal all our stuff again
Dig up diamonds and craft those diamonds
And make some armor, get it, baby
Go and forge that like you so MLG pro
The sword's made of diamonds, so come at me, bro, huh

### 3/5 — Wish there wasn’t so many ads

*2024-10-16, version 1.0*

I like this app like really really goodly but there’s one thing that annoys me all those god darn ads!!!!! do you know what I mean don’t you guys?
