## Review summary

i48 offers a realistic HP48 experience with easy setup and skins, making it a nostalgic replacement when a real device isn’t available. However, multiple reviews cite stability and maintenance problems: freezes, input lag, unresponsive keys, data loss after reinstall, and regressions after updates. The core appeal remains strong, but reliability and ongoing iOS compatibility require attention.

### Pros

- Realistic HP48 look and feel with great skins.
- Easy setup and a feature-rich emulator.
- Haptic feedback and responsive input.
- A solid HP48 replacement when the real device isn't available.

### Cons

- Frequent freezes/crashes and general unresponsiveness, especially after switching apps.
- Not maintained and often incompatible with the latest iOS/devices; updates can regress functionality.
- Input issues: several keys sometimes don’t register, input lag, and flaky bottom keys.
- Memory/variable loss after reinstall; memory recovery prompts can be unresponsive.
- Updates that introduce lag or otherwise degrade performance.
