## Review summary

Users praise the app’s polished UI and the ability to view memory, CPU, and storage at a glance, along with beginner-friendly explanations. However, the majority of reviews converge on three issues: persistent monetization through subscriptions and login requirements with privacy concerns; surprising billing problems and alleged hidden charges; and reliability gaps including incorrect data, blank device info, and update bugs that hinder use. Overall, many feel the app is not worth the price, as it offers limited process-level detail and analytics despite strong visuals.

- Provides memory, CPU, and storage usage at a glance.
- Works well for some users and fulfills its basic promises.
- Helpful for newbies to understand iPhone health outcomes.
- Includes unique 3-D graphics that some users appreciate.

### Cons

- Subscription model and login requirement (privacy concerns).
- Recurring charges and hidden billing not visible in subscriptions.
- Inaccurate memory/RAM readings and device information sometimes blank.
- Bugs after updates: hangs, cannot restore/unlock.
- Limited usefulness: does not show running processes; limited analytics.
