Neutral/Mixed Reviews
- "Good but could be better for body variety" (AppSupports, 2024): "Arm slimming works well for basic tweaks, but it pushes a 'stereotypical' slim body ideal. Wish there were more diverse model examples to match real shapes."
- "Fun for arms, but inconsistent on skin" (Reddit r/MakeupAddiction, 2023): "The slim arm editor is handy for trying looks, but it doesn't always blend with uneven arm skin—ends up looking contoured weirdly if you're not careful."
Negative Reviews
- "Overhyped for body edits" (App Store, 2024): "Arm tool is okay for minor changes, but for anything real, it just makes arms look fake and skinny like a model—not helpful for natural tones."
