## Review summary

Reviewers praise iDOS 3 as a capable DOS emulator for iPad with mouse/keyboard support and strong game compatibility, plus flexible drive mounting and ad-free value. However, recurring issues include multi-disk installation hurdles (no easy disk swap), incomplete disk-image support (.img/.iso), performance problems on some devices, and control/keyboard mapping challenges. Despite the learning curve, many consider it worth the investment for retro DOS gaming on iPad.

### Pros

- Plays classic DOS games on iPad with mouse and keyboard support.
- Flexible drive management: can mount folders and CD/DVD ISO backups as virtual drives.
- Broad compatibility with beloved titles (e.g., Doom, Wolfenstein 3D, Quake via QDOS).
- No ads and low price, offering good value.
- Generally praised as a capable emulator and a positive way to experience retro DOS gaming on iPad.

### Cons

- Multi-disk installation is cumbersome: no easy way to unmount/swap floppy disks during install; need a UI to manage multiple disks.
- Disk image support gaps: not mounting .img/.iso files; requests for broader disk-image formats.
- Performance issues on some devices (e.g., frame rate very low on certain iPhone models) hindering playability.
- Control/keyboard mapping problems for certain games and difficulty performing keys like Ctrl-Alt-Del.
- Learning curve present: users note it isn’t immediately intuitive and requires setup to get games running.
