## Review summary

Users praise Fluidity HD for its calming, visually soothing experience and its value as a sensory tool for children and users with disabilities. However, the app is repeatedly described as abandoned and incompatible with modern iOS, with frequent crashes and instability that render it difficult or impossible to use on current devices.

### Pros

- Nostalgic favorite with soothing, lava-lamp–like visuals that light up the room.
- Used as a sensory tool for kids and people with disabilities, aiding calm and engagement.
- Simple, low-effort interaction suitable for short sessions.

### Cons

- No longer updated and incompatible with the latest iOS versions, making it unusable on current devices.
- Frequent crashes and instability, including gesture-related crashes and glitches.
- Overall reliability suffers due to aging code, leading to a perception of abandonment.
