## Review summary

Reviews for Gravity by Vaonis are mixed. The main drawbacks are privacy concerns over full photo library access and recurring reliability bugs (QR code failures, black screens, tracking problems, and updates that break features). Performance and feature gaps (slowness, low image resolution due to cropping, limited object tracking) further hamper use. Positive notes center on helpful tutorials, ease of use for some Hestia users, and the potential for impressive astrophotography and educational value when the system works. Overall, privacy and reliability are the dominant pain points, with room for improvement in support and updates.

- Capable of impressive astrophotography when it functions (eclipse photos and deep-sky shots)
- Educational value for educators and students

### Cons

- Requires full access to the photo library, raising privacy concerns
- Frequent reliability issues: QR code does nothing, black screen, tracking problems, updates breaking features
- Slow performance and limited capabilities: app slow, limited photo resolution due to cropping, inconsistent object location/tracking
- Support and responsiveness concerns (poor support or unresponsive queries)
